Got any tips in shading stuff in black and white digitally?

Hi Anon!

You're in luck! I'm currently wrapping up a book which is shaded digitally, so I've been thinking a lot about this recently.

How I do this is by no means the only way, so take from these tips as much or little as you want! When I add grays and shadows to a line art drawing, I try to think about these things:

Preparing the image

I like to work with a file that has a white background and a layer with only line art on top of it. Between these two layers I add new layers where I use the pen tool and bucket to fill areas with black, then I lower the opacity for that layer to get a value that I want.

This method works well for me, and for simpler pieces I don't need more than 3 layers with different values - light, medium and dark grays.

I work in Clip Studio. Here's a picture of the layers of a recent drawing. Each layer is actually completely black but you can see the opacity percentages by each layer. Lower percentage -> brighter value. This makes it super duper easy to change the value of a layer, no need to repaint it, just change the opacity!

Value composition

For the best result, do a couple of value sketches with a limited set of values and find something that works well for the image. Getting the values right is what will improve the image the most! Here's a quick tutorial on muddycolors. Muddy Colors is a very nice art blog to check out. Looking at grayscale storyboard drawings or value sketches are great ways to pick up on this too.

I try to group values when working with grays. Take this image for example:

The character in the foreground has mainly dark grays, which separates her from the background, which has mostly light grays. Then the windows are white and the roof black.

Value composition is a huge and complex area and I recommend anyone wanting to learn to be more conscious about their values and to do value sketches. Analysing art you think has good values is great too.

Shadows

Not every piece needs shadows, but they can add a lot to an image! I use three kinds of shadows when I work in grayscale.

Inked shadows - these shadows are added during the inking stage and usually show areas where light would have almost no way of getting there, such as under this tent.

Gradient shadows - these shadows usually represent something getting further and further away from a light source or an area that would bounce light. This tree receives a tiny bit of light from a campfire on the ground and moonlight that bounces on the ground and up, fading as we get higher up in the tree. But mainly I add these gradients in ways that look cool and will help the overall composition.

Hard shadows - these shadows appear when a strong light casts shadows and can be used on a shape or to cover something. Here's a werewolf with shadows on its back, which gives it a better sense of mass and is interesting visually!

You can also cover an area in shadow like this, where the tree casts a shadow down on the archer and the cliff.

Texture

I like to add a layer of noise as a finishing touch. In Clip Studio you can create a noise layer with Filter->Render->Perlin noise... Find a balance of scale and amplitude that works for the image, then change the layer mode to "Vivid Light" and lower the opacity of the layer to around 30%. I like how this looks, it's not super visible usually but helps make the drawing feel less artificial and digital.

I hope that helps! Here are some nice links too:

3 things:

What's a song, band, album, or playlist you want to shout out?

What are your opinions on pets (dog, cat, neither, other)?

Finally, what's a boring fact about you?

Cheers, have a good one.

Oh yes!

Shoutout a band? SEEMING, SEEMING, SEEMING BABY! They're even on tumblr: @seemingmusic

Their music is great and the lyrics are freaking phenomenal poems and I have no idea why they're not among tumblr's favorites like? "The future will be borderless, and red and queer and bold, for I was born to make my kind extinct" (End Studies) "Dreamt of gutting billionaires... But when I woke, blood was gone" (Go Small) you've got the eat the rich be queer do crime philosophy all over it! "Like a tall tree, I am pining to be taken up by the lightning! Strike me! I dare you! I dare you! Heaven, hear me! Like a mantis, I am praying, out of habit, without saying anything, for the bloody sting of a kestrel come to snatch me" (Remember to Breathe) it's got puns it's got self destructive thoughts it's got vague religious implications which I'm not a fan of personally but you guys seem to love it when it's Hozier. And who can ignore "To the gunmen who guard against all of the starving: God will bury you, nature will bury you [...] To the terrified rich man: God will bury you. To the killers of animals: nature will bury you." (The Burial) like don't tell me that doesn't go hard. (Personally I like to think of The Burial as not a threat but a loving promise. It continues "To the worshipper of justice, the reliance on reason, and the fire in your eyes: God will bury you, nature will bury you, time will bury your bones unseen. Total and absolute. Infinite amplitude. Till all the black is ripe and green." and because honoring the dead and burying them is an important act of kindness, I like to think of this as a promise that no matter who you are, no matter who you leave behind to mourn you, you will be buried. You will die and you will return to the Earth and you will be lovingly welcomed, it is inevitable and inescapable, I promise. I know I already rambled about this when I reblogged that worm poem post but I will keep talking about it because I love it and I don't know how many people actually read it.) There's so much more I want to say but I'm on mobile in bed hours past bedtime and this paragraph is probably already way too long and disorganized so like maybe tomorrow but! Regardless of whether you can listen to the music I highly recommend reading some of the lyrics here: https://seemingmusic.tumblr.com/text

Anyway moving on from minor infodump, I'm not entirely sure what you mean by your second question like are you asking my opinion on pets as a concept or my preferences for having pets or? I think humans love to pack bond with things that are not humans and as long as the human is able to meet the needs of an animal to create a mutually beneficial relationship that's a good thing, but ideally you should opt for domesticated animals (animals that have been our companions for so long they are genetically distinct from their wild counterparts) since they are best adapted to living with humans. I was practically raised by cats living with my workaholic single mom and our cats so personally I love cats and probably have a better time connecting with them than I would other common pets like dogs. Currently mom and I are sharing two cats, brothers, but one rarely visits me while the other is obsessed with me but I suspect this is because a) I always have his favorite snack available (potato chips. yeah I don't think he knows he's a cat) and b) I pet him the way he likes best (which is a lot of rubbing and scratching his spine by the tail intermittent with chin scritches, but he wants you to be firm with it as though he were a dog... again this man is not aware he's a cat).

A boring fact about me... Well easy mode is just "I have two feet" or "I ate a sandwich for breakfast today" but let me try to think of something a bit more personal yet still uninteresting... I have watched less than one episode of Supernatural. Yeah that's boring yet specific.

Thank you so much for the ask sorry my reply is a little messy I was already in bed when I got this!

"Mystery on a Moonlit Cruise" Track 7

Location: Party Hall

Nanaki: I wanted to talk about what happened just before we arrived at the door to the party hall—

ーFlashback

Nanaki: …How strange.

Ryui: What? Who’re you calling strange?

Nanaki: Sorry, I wasn’t referring to you, Ryui-san.

I was just thinking about how quiet it’s become on board. What happened to the background music they were playing earlier…? Did they forget to put it on loop? 

Yukikaze: Oh, yes, I remember that.

Nanaki: There’s meant to be service robots in charge of shuffling through songs to play on board. If the music has turned off, that means the humans aren’t the only ones affected here, but robots too.

Kinari: …

Muneuji: (It’s true…I’m struggling to make sense of how an android such as Azekawa-san could have fallen asleep too.)

Nanaki: Again, it might not mean anything but I think it’s worth looking further into.

Muneuji: I see your point. Very well then, why don’t we begin by investigating the service robots in this room?

Yukikaze: Good idea. I’ll help however I can.

Nanaki: What do you think, Yowa-san?

Netaro: I thiiink this paella is out of this world!

Nanaki: I-I see. We’ll let you know if we make any discoveries then.

Netaro: Aye, aye!

Muneuji: Let’s see, I believe they should be stationed—

Yukikaze: There—Hmph!

Muneuji: An impeccably executed crouch start…!

Nanaki: He’s running in a zig-zag pattern to avoid all the sleeping people…!

Yukikaze: Phew.

Muneuji: You've collected the four service robots stationed in the corners of the room and brought them all the way back here. Trained athletes truly are a league beyond us.

Yukikaze: Nanaki, will this do?

Nanaki: Yes, thank you. I just need to connect to this robot with Andy’s offline mode…there we go.

Muneuji: …This looks like the screen that shows up when you’re composing.

Nanaki: Yeah, it’s the same one. I’ll be able to find out the exact moment the robots shut down by checking when the background music cut off—

…Huh?

Yukikaze: What’s the matter?

Nanaki: It says this robot was playing some popular therapeutic music tracks, but there’s just one issue…

Something looks off with the sound waves in the 5 minute period before it entered sleep mode…?

Netaro: Mm? Ers homhing hwong wih he hounwaes?

Muneuji: Yowa-san. It’s difficult to understand you while your mouth is full of paella. Please take a moment to properly chew and swallow before you begin speaking again.

Netaro: Nom nom…

Muneuji: Chewing at least 30 times per bite would be ideal.

Netaro: Nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom nom…gulp.

There’s something wrong with the sound waves? How can you tell!?

Nanaki: The amplitude just seems a little strange for a song that’s meant to be relaxing.

Netaro: Which bits look weird to you?

Nanaki: Take this V shape for example—

Yukikaze: I’m afraid I don’t have a clue what they’re talking about.

Muneuji: Let’s have some paella while we wait for those two to finish their analysis.

Netaro: You were able to deduce all that information that quickly~? I'm blown away!

Nanaki: I’m still not sure if this relates to the sleeping situation that’s going on though…

Netaro: Doesn’t matter if it does or doesn’t! I still think that brain of yours is amazing, Nana!

I dunno why you didn’t tell us sooner?

Nanaki: Uh…

Ryui: YOWA!!!!!

Netaro: Uoh!?

Ryui: You little shit, I know you’re hiding something.

Muneuji: Have you uncovered a clue, Ryui-san?

Ryui: (There’s no shot that I can tell them a spirit warned me that something’s up with Yowa…but it’s not like I have to go easy on this guy so I’ll just force the confession right outta him!)

I know what the fuck you did so you better just admit it and end this shitstorm! 

Netaro: Yep, I did it!

Ryui: Even if you try lying your way out of this I won’t—wait, what?

Netaro: Ryui’s spot on! I’m the crook who turned this room into a forest of dreams!

Nanaki: Huh…!?

Netaro: Oh, would you look at that, it's finally time.

Muneuji: Time for what?

Toi: Nngh…yawn…

Ryui: Toi!?

Technique simultaneously locates multiple defects on microchip circuits

Defective computer chips are the bane of the semiconductor industry. Even a seemingly minor flaw in a chip packed with billions of electrical connections might cause a critical operation in a computer or other sensitive electronic device to fail.

By modifying an existing technique for identifying defects, researchers at the National Institute of Standards and Technology (NIST) have developed a method that can simultaneously locate individual electrical flaws in multiple microcircuits on the same chip. Because the technique relies on a relatively inexpensive and common imaging tool, an atomic force microscope (AFM), it may provide a new way to test the interconnected wiring of computer chips in the factory.

An AFM features an ultrasharp tip attached to a tiny cantilever that vibrates like a diving board. In the standard mode of operation, scientists apply an AC (alternating current) voltage to the tip as it scans across individual wires buried in parallel several micrometers (millionths of a meter) below the surface of a silicon chip. The voltage difference between the tip and each wire generates an electric force revealed as changes in the frequency or amplitude (height) of the vibrating tip. A break or defect in a wire will show up as an abrupt change in the vibration of the tip.

Poetic Reading Machine

You can feed this machine with information, it will dissect those information into word that can only move when you read out loud or make some noise. Basically, you are the one in control of your own reading speed, though to some extent, you cannot. So, there is two option, if you indeed are slower than the machine, will you rush in order to catch it, or will you stop, slow down and don’t care about its pace? This machine replicates, perhaps, our daily lives when we are constantly in a rush for productivity. Time itself is (product)ivity. If you see time this way, then indeed, we are running out of time. Yet, if you think beyond time as a clock monitoring productivity, then you can have all the time in the world. Time, then, is liberating. Free from any modes of producing, time is personal and emotional, connecting to one’s own experiences. Time cries, time laughs, and time shares. I hope that, through this small machine, eventually, you can start reclaiming time as not a product but an endearing entity that will nurture your mind, your heart and your soul.

Knowing Dynemech Anti Vibration Foundation Isolation Is Crucial for Controlling all types of Industrial Vibrations

Does the Vibration of surrounding machinery influence your precise machines? A tried-and-true method for controlling vibration in industrial environments, both actively and passively, is foundation isolation. To control the impact of vibration in machinery and guarantee the best possible performance from industrial vibration machines, this method is essential.

Major Advantages With Dynemech Foundation Isolation Technologies :

Decreased centre of gravity and better weight dispersion for increased machine stability.

Maintained the alignment of the equipment throughout dynamic activities.

Effective vibration isolation reduces vibration transmission to nearby locations.

Safety measures for delicate machinery and measuring devices

Reduced impact of vibration on machine functioning, resulting in improved accuracy and durability

ideal for: Active Vibration Management, Presses for power, Hammers Forging, Engine Testing Rigs, hefty industrial equipment, Turning Machinery

#Vibration Protection Through Passive, Accurate Machining Facilities, Testing and Measuring Devices, Laser Blades, The microscopes, Machine Equipment, Rail pads for cranes, Techniques for Isolating Vibrations:

Specialized mounts known as "Anti Vibration Mounts" serve as vibration isolators, therefore minimizing the transfer of vibrations between equipment and its environment. They provide limited displacement capabilities and dynamic stiffness to improve isolation performance

The addition of an inertia block to the foundation design may greatly improve stability and vibration dampening for large machinery.

Industrial vibration machines benefit from the inertia block's assistance in controlling coupled modes of vibration.

Advanced dampening systems may further reduce vibration amplitude and enhance machine performance when used in tandem with anti-vibration mounts. These systems efficiently reduce the impact of vibration in machinery by controlling vibrations using energy dissipation methods.

Concrete basis: Effective foundation isolation and machine levelling depend on a well-designed concrete basis with the appropriate weight distribution.

Stabilizers: By including stabilizers into the foundation construction, industrial equipment may remain balanced and experience less unintended movements.

Specialized mounts with adaptable damping properties, such as hydraulic mounts, are perfect for applications with different vibration frequencies and amplitudes.

A Precision Engineering Method:

For best results, our vibration isolation systems use precise engineering techniques:

Analysing isolation needs for each application in detail

Custom-made inertia blocks and vibration isolators, Including technologies for active isolation in dynamic situations,

Weight distribution optimization and foundation design, In vibration analysis, coupled modes are taken into account.

Machine levelling procedures are used to increase stability,dampening system design that is specific to each industrial vibration machine

# Pro Tip: When you need to shield delicate equipment from adjacent vibration sources or control vibrations from large industrial machines, foundation isolation is essential. In particular, industrial vibration machines and applications using crane rail pads need a vibration control approach that takes into account your facility's unique isolation needs.

Some common types of laser parts

Laser systems are composed of various laser parts that work together to produce, manipulate, and direct laser beams. Here are some common types of laser parts:

Laser Resonator: This is the optical cavity that forms the core of a laser system. It includes mirrors or other reflective surfaces that help to amplify the laser beam through multiple passes.

Gain Medium: This is the material that actually produces the laser light through a process of stimulated emission. It can be a solid (like in a ruby or Nd:YAG laser), a gas (like in a CO2 laser), a liquid (like in a dye laser), or a semiconductor (like in a diode laser).

Pump Source: This is the energy source that excites the gain medium to produce laser light. It can be an electric current, a flash lamp, or another laser.

Optical Components:

Lenses: Used to focus or diverge the laser beam.

Beam Expanders: Used to increase the diameter of the laser beam.

Mirrors: Used to direct or reflect the laser beam, often coated to maximize reflectivity at the laser's wavelength.

Windows: Transparent materials that allow the laser beam to pass through while protecting the laser cavity from the environment.

Polarizers: Used to select the polarization state of the laser beam.

Waveplates: Used to manipulate the phase and amplitude of different polarization components of the laser beam.

Laser Diodes: These are semiconductor devices that emit coherent light when an electric current passes through them. They are used in many types of lasers, including direct-diode lasers and as pump sources for solid-state lasers.

Q-Switch: A device used to control the timing of the laser pulse, allowing for the production of high peak power pulses.

Mode-Locking Devices: These are used to produce very short pulses by causing the laser to lase in many longitudinal modes simultaneously.

Amplifiers: Used to increase the power of a laser beam without changing its characteristics.

Attenuators: Devices that reduce the power of a laser beam, often used for safety purposes.

Scanners and Deflectors: These are used to direct the laser beam in a specific pattern or to a specific location, often in laser marking or cutting applications.

Cooling Systems: Lasers, especially high-power ones, require cooling to prevent overheating. This can be done with water-cooled chillers, air cooling, or thermoelectric coolers.

Control Systems: These include the hardware and software used to operate the laser, such as power supplies, computer interfaces, and motion control systems.

Safety Equipment: Including safety goggles, beam dumps (to absorb excess laser light), and interlock systems to ensure the laser is not accidentally operated when the protective covers are open.

Laser Safety Shutters: Automatically controlled shutters that can block the laser beam in case of an emergency or when maintenance is being performed.

Power Meters and Energy Meters: Devices used to measure the power or energy of the laser beam, which is important for process control and safety.

These are just a few examples of the many laser parts that can be found in a laser system, and the specific components will vary depending on the type of laser and its intended application.

Mercedes-Maybach EQS SUV: energia luxuosa já chegou à Soc. Com. C. Santos

O Mercedes-Maybach EQS SUV, o primeiro modelo 100% elétrico da marca de luxo do Mercedes-Benz Group, já chegou à Sociedade Comercial C. Santos. O imponente modelo é baseado no Mercedes EQS SUV e tem ainda mais requinte e exclusividade.

O Mercedes-Maybach EQS SUV tem vários detalhes que marcam a diferença face ao modelo Mercedes-Benz. Além da lendária pintura em duas cores (opcional), destaca-se a grelha dianteira com a estrela no capot. Mas há muito mais pormenores que diferenciam este luxuoso modelo, quase sempre com o símbolo Maybach a marcar presença. Exemplo disso são as jantes (que podem ser de 21 ou 22 polegadas), os nichos dianteiros, as extremidades laterais do para-choques e, entre outros, os estribos laterais.

Interior com luxo e requinte de exceção

Se o exterior impressiona, o interior é ainda mais marcante. E não surpreende, porque o luxo e qualidade está no ADN da marca. Afinal, “apresentar o melhor dos melhores” foi a ambição expressa por Karl Maybach e o seu pai Wilhelm quando, em 1921, estrearam o Maybach 22/70 HP W 3.

O habitáculo do Mercedes-Maybach EQS SUV tem, além do MBUX Hyperscreen, bancos do tipo executivo em couro Nappa processada sustentavelmente, sistema de som surround Burmester 4D e ecrãs de 11,6 polegadas para os lugares traseiros, entre outros equipamentos. A propósito de lugares traseiros, os passageiros viajam com todo o luxo em duas poltronas com encosto de cabeça almofadado (tal como à frente), embutidas em madeira. Entre os dois bancos está um frigorífico com flutes (que podem ser pousadas entre os dois bancos, quando necessário) equipados com ventilação, função de massagem e aquecimento de pescoço e ombros. Destaque especial para o modo Chauffeur (opcional) no assento traseiro direito, em que o banco do acompanhante da frente se desloca mais para a frente e o apoio de costas rebate, aumentando espaço para pernas e visibilidade do ocupante do banco traseiro desse lado, enquanto o apoio de pernas sobe. Uma nota de requinte em termos de conforto é o reforço do isolamento acústico, em particular, para os ocupantes dos lugares traseiros, já que nessa área da carroçaria foi aplicado um incremento de espuma acústica e revestimentos em couro sintético.

Portas com funcionamento automático

Outra característica exclusiva deste SUV elétrico são as portas de conforto automáticas (de série à frente e atrás). A porta do condutor abre-se automaticamente quando este se aproxima do veículo a uma distância de cerca de 1,5 metros (função pode ser ativada e desativada no visor central do MBUX). Todas as outras portas podem ser abertas e fechadas remotamente através do MBUX – com um simples toque na chave do veículo ou no visor central ou no MBUX High-End Rear Seat Entertainment padrão. A porta do condutor também fecha automaticamente assim que o pedal do travão é pressionado.

Potência máxima e conforto de topo

Este exemplar mais luxuoso da família de modelos elétricos recebe um novo sistema propulsor, identificado por 680. Este inclui dois motores, um em cada eixo, e tem uma potência máxima combinada de 658 cv e um binário de 950 Nm (mais 125 cv e 92 Nm de binário que o Mercedes EQS SUV 580 4MATIC). Toda esta potência faz com que, não obstante 5,125 metros de comprimento e cerca de três toneladas de peso, o modelo ��dispare” dos zero aos 100 km/h em apenas 4,4 segundos. A velocidade máxima está limitada eletronicamente a 210 km/h.

Para além dos programas de condução DYNAMIC SELECT ECO, SPORT, OFFROAD e INDIVIDUAL, o Mercedes-Maybach EQS SUV dispõe do programa de condução especial MAYBACH. Substitui o clássico programa COMFORT e foi concebido inteiramente para proporcionar o máximo conforto de condução aos passageiros traseiros. Garante que existem movimentos corporais mínimos sob os bancos traseiros. Um nó de oscilação está aí localizado, de modo que as amplitudes são mais baixas. O programa de condução MAYBACH é a definição padrão do modelo.

A bateria de 108,4 kWh do Mercedes-Maybach EQS SUV permite uma autonomia de 600 km com uma só carga. Uma vez esgotada a energia, o carregamento em corrente contínua (DC) a potências de até 200 kW. Isso significa que pode obter até 220 km de autonomia em 15 minutos ou recarregar de 10% a 80% em apenas 31 minutos. Em corrente alternada (AC), o modelo pode carregar a potências de até 22 kW. Em wallboxes domésticas com aquela capacidade o carregamento total da bateria demora 5,5 horas.

Unboxing especial de um modelo excecional

Guide to Using a Spectrum Analyzer for Harmonic Measurement

A spectrum analyzer is an instrument used to measure signal spectra, displaying frequency components and their relative amplitudes, aiding engineers and technicians in understanding signal characteristics. In spectrum analysis, harmonics are crucial. Harmonics are integer multiples of the fundamental frequency signal, typically generated by nonlinear systems. In audio, radio frequency (RF), and power systems, the presence of harmonics can lead to issues like interference and efficiency loss. Understanding and managing these harmonics are vital to ensuring the proper operation of systems. SPA-3P6G_Spectrum Analzer Usage Guide: Measuring and Analyzing Harmonics • Understanding Harmonics Basics: Harmonics are signals with frequencies that are integer multiples of the fundamental frequency. While pure signals ideally lack harmonics, real-world systems with nonlinear components generate them. • Selecting the Right Spectrum Analyzer: Choose a spectrum analyzer that covers the frequency range of the signal of interest and its harmonics. • Preparing the Spectrum Analyzer: Preheat the spectrum analyzer for stability and accuracy. Check calibration status and calibrate if necessary. • Setting Spectrum Analyzer Parameters: Set parameters like center frequency, frequency span, resolution bandwidth (RBW), video bandwidth (VBW), and scan time based on signal characteristics. • Connecting the Signal Source: Use appropriate cables to connect the signal source to the spectrum analyzer’s input port. If using antennas, ensure correct installation and orientation. • Initial Scan: Perform an initial spectrum scan to observe signal distribution across the frequency range and identify the fundamental frequency and harmonic ranges. • Precisely Locate Fundamentals and Harmonics: Adjust center frequency and frequency span to center the fundamental frequency on the display. Use narrower resolution bandwidth for accurate frequency measurements. • Measure Harmonic Amplitudes and Frequencies: Utilize the spectrum analyzer’s marker function to measure harmonic amplitudes and frequencies, ensuring amplitude calibration accuracy. • Analyze Harmonic Spectrum Characteristics: Analyze harmonic frequency, amplitude, bandwidth, and modulation type to identify harmonic sources and generation mechanisms. • Using Tracking Generators: If the spectrum analyzer has a tracking generator, generate signals at the same frequencies for further analysis and harmonic source localization. • Time Domain Analysis: Some spectrum analyzers offer time-domain analysis to observe transient characteristics of harmonic signals. • Advanced Spectrum Analyzer Features: Utilize features like max hold, min hold, and averaging modes to reduce random noise effects for clearer harmonic observation. • Harmonic Source Localization: Based on measurement results, attempt to localize harmonic sources. Move the spectrum analyzer or use directional antennas if necessary. • Harmonic Suppression Measures: Upon identifying harmonic sources, implement corresponding suppression measures such as filtering, cable rearrangement, device setting adjustments, or using harmonic filters. • Documentation: Record measurement processes and results, including harmonic frequencies, amplitudes, possible harmonic sources, and suppression measures taken. • Continuous Monitoring: After addressing harmonic issues, regularly monitor using the spectrum analyzer to ensure harmonics do not reoccur. • Maintenance of Spectrum Analyzer: Regularly maintain and calibrate the spectrum analyzer to preserve its performance and accuracy. • Advanced Analysis: For complex harmonic issues, conduct advanced analyses such as total harmonic distortion (THD) analysis, power spectral density analysis, or modulation spectrum analysis. Precautions： • Ensure input signal levels do not overload to avoid measurement errors. • Consider the modulation characteristics of signals, as modulation may affect harmonic measurements and analysis. • Use specific measurement accessories (such as harmonic mixers or harmonic filters) for particular harmonic measurement tasks. • Be mindful of DC components in signals, as they may affect measurement results. • Consider environmental factors (such as temperature, humidity, and electromagnetic interference) that may influence measurement results. • By following these steps and precautions, the spectrum analyzer can be a powerful tool for measuring and analyzing harmonics, assisting engineers in enhancing system performance and reliability.
