If you\u2019re asking this question, it means you\u2019re ready for an upgrade.&nbsp;<br><\/p>\n\n\n\n<p>Multimeters are good but oscilloscopes are a step above. As far as tracking voltage and fixing wonky circuits are concerned, they\u2019re the best at what they do. But before we dive in, just know that an oscilloscope is an investment. A good quality scope can cost a lot, make no mistake, it\u2019s worth it.&nbsp;<br><\/p>\n\n\n\n<p>We\u2019ll cover the reasons why that is later on but first, a quick definition.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is an Oscilloscope?<\/h2>\n\n\n\n<p>An oscilloscope is a tool used to track changes in voltage over time by displaying electronic signals as waveforms. They\u2019re typically used by electronic technicians and engineers, but believe us when we say there\u2019s a whole host of <a href=\"https:\/\/www.circuitspecialists.com\/blog\/professions-which-use-oscilloscopes\/\">professions which use oscilloscopes <\/a>&nbsp;on a regular basis.<\/p>\n\n\n\n<p><br>There are two types: analog and digital. As you can guess, digital \u2018scopes are the more modern model. But both types definitely have their distinct advantages.<\/p>\n\n\n\n<p>We\u2019ll leave it at that, but you can always check <a href=\"https:\/\/www.circuitspecialists.com\/blog\/what-is-an-oscilloscope\/\">what is an oscilloscope<\/a>, for a more in-depth definition.&nbsp;<br><\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"What is an Oscilloscope?

Maybe you need to accurately measure the time between circuit changes. Or maybe you simply need a more refined system for troubleshooting?<br><\/p>\n\n\n\n<p>Whatever the case is, it\u2019s a good idea to get all your expectations and requirements down on a piece of paper\u2014or, at the very least, somewhere visible.

However, as mentioned earlier, physical differences aren\u2019t visibly noticeable at first glance.<br><\/p>\n\n\n\n<p>Aside from being lighter and more portable, digital oscilloscopes also:<br><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Use an ADC to sample the input<\/li><li>Have a small computer and LCD monitor to plot the samples (earlier models use CRT, like analog \u2018scopes)<\/li><li>Capable of <a href=\"https:\/\/www.tek.com\/support\/faqs\/what-fft-fast-fourier-transform-math-function-oscilloscope-useful\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">mathematical operations like FFT<\/a><\/li><li>Can provide on-screen measurements, storage, and even printing<\/li><li>Have higher bandwidths than analog \u2018scopes<\/li><\/ul>\n\n\n\n<p>Basically, digital models are more intuitive and responsive. They suit the modern user perfectly due to all the neat little tricks packed in their tiny frame\u2014like single measurement period plotting, on-screen measurement displays, and actual mathematical operations.<br><\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Note<\/h5>\n\n\n\n<p>Digital oscilloscopes are susceptible to the pitfalls of aliasing artifacts; something analog \u2018scopes don\u2019t have to worry about. So, yes, digital \u2018scopes do seem to have a lot going for them, but they\u2019re not without their own flaws.\u00a0<br><\/p>\n\n\n\n<p>Still, as a first-time buyer of oscilloscopes, you might find digital models easier to use. They\u2019re a little more user-friendly and forgiving than analog \u2018scopes (which is something a lot of beginners want). There\u2019s also the whole \u201cnot a lot of manufacturers produce analog models anymore\u201d situation we mentioned earlier.<br><\/p>\n\n\n\n<p>As we mentioned earlier, the <a href=\"http:\/\/www.circuitstoday.com\/analog-oscilloscope-vs-digital-oscilloscope\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">differences between analog and digital<\/a> are more apparent in their performance. But we\u2019ll focus on the main difference between the two \u2018scopes for now, which is how they display waveforms.&nbsp;<br><\/p>\n\n\n\n<p>Analog oscilloscopes show waveforms immediately as they are. Digital oscilloscopes sample the original waveform first before converting it into digital numbers and then displaying it (and storing it).<br><\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to draw an arbitrary waveform using a function generator from Siglent\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/sjcqGy2z9PA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><figcaption>How do draw an arbitrary waveform.<\/figcaption><\/figure>\n\n\n\n<p>The good news is that there isn\u2019t that large of a learning curve when <a href=\"https:\/\/www.youtube.com\/watch?v=iXvFw6KyAew\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">transitioning from one type to the other<\/a>. Once you know how to use an analog oscilloscope, you\u2019ll have no problems using a digital one\u2014and vice versa. The controls and display might be a little different but, overall? They\u2019re both pretty straightforward in terms of operation, and both measure voltage changes like a champ.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Manufacturer<\/strong><\/h3>\n\n\n\n<p>Once you start shopping around for oscilloscopes, you might notice that the brands Tektronix and Keysight (formerly known as Agilent or HP) pop up literally <em>everywhere.<\/em><br><\/p>\n\n\n\n<p>No surprise there; they\u2019re the two biggest giants on the oscilloscope playground. Everyone knows who they are because:<br><\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>they\u2019ve been around for years, and<\/li><li>their quality is <em>off the charts<\/em>.<\/li><\/ol>\n\n\n\n<p>You want the best? You get whatever has their brand stamped on the box. However, that stamp doesn\u2019t come cheap. In fact, when it comes to their products, you usually pay top dollar\u2014and <em>then <\/em>some.<br><\/p>\n\n\n\n<p>Make no mistake; their \u2018scopes <em>are <\/em>fantastic.<br><\/p>\n\n\n\n<p>But if you\u2019re on a budget, fret not. Oscilloscope manufacturers have had ample time to step up their game.

Look for brands like Hantek, Siglent, LeCroy, Phillips, and Rhode &amp; Schwartz. These guys have great \u2018scopes at pretty reasonable prices.<br><\/p>\n\n\n\n<p>So how do you buy an <a href=\"https:\/\/www.circuitspecialists.com\/digital-storage-oscilloscopes\">oscilloscope<\/a>? You can check out our online store Circuit Specialists to determine the best oscilloscope for your needs. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Bandwidth<\/strong><\/h3>\n\n\n\n<p>When it comes to choosing an oscilloscope, and asking yourself how do I buy an oscilloscope, bandwidth is arguably one of the most important specs (if not <em>the <\/em>most important).&nbsp;<br><\/p>\n\n\n\n<p>It indicates the highest frequency signal the \u2018scope is capable of capturing. If the frequencies you typically measure are on the higher end of the spectrum, you\u2019ll want a \u2018scope with a decently hefty bandwidth\u2014maybe a couple hundred megahertz or a gigahertz, to start. But if you know your frequencies won\u2019t go beyond several hundred kilohertz, you <em>can <\/em>definitely settle for a lower bandwidth.&nbsp;<br><\/p>\n\n\n\n<p>You can find more in-depth reasons regarding bandwidth\u2019s importance to your oscilloscope decision <a href=\"https:\/\/blog.adafruit.com\/2012\/01\/27\/why-oscilloscope-bandwidth-matters\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">here<\/a>.<\/p>\n\n\n\n<p>The trick is selecting a \u2018scope with a bandwidth that can safely accommodate your needs <em>and<\/em> give you some wiggle room to grow <em>without <\/em>wasting your money on performance you won\u2019t need. Bandwidths that are more or less in the middle range (50MHz to 500MHz) are usually safe bets.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Sampling Rate<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.circuitspecialists.com\/blog\/wp-content\/uploads\/2021\/02\/Untitled.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"668\" src=\"https:\/\/www.circuitspecialists.com\/blog\/wp-content\/uploads\/2021\/02\/Untitled.png\" alt=\"\" class=\"wp-image-4862\" srcset=\"https:\/\/www.circuitspecialists.com\/blog\/wp-content\/uploads\/2021\/02\/Untitled.png 1000w, https:\/\/www.circuitspecialists.com\/blog\/wp-content\/uploads\/2021\/02\/Untitled-300x200.png 300w, https:\/\/www.circuitspecialists.com\/blog\/wp-content\/uploads\/2021\/02\/Untitled-768x513.png 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/a><figcaption><a href=\"\/siglent_sds2102x-plus_100mhz_2_channel_digital_storage_oscilloscope.html\">Siglent SDS2102X-PLUS<\/a> 100MHz 2 Channel Digital Storage Oscilloscope<\/figcaption><\/figure>\n\n\n\n<p>The second thing to look for when asking yourself how do I buy an oscilloscope is the sampling rate. The sampling rate is what a digital oscilloscope uses to reconstruct the signal. Most scopes have <a aria-label=\" (opens in a new tab)\" href=\"https:\/\/www.testandmeasurementtips.com\/difference-real-time-equivalent-time-sampling-oscilloscope\/\" target=\"_blank\" rel=\"noreferrer noopener\">two different sampling rates<\/a> (also called modes):<br><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>real-time sampling<\/li><li>equivalent-time sampling (or repetitive sampling)<\/li><\/ul>\n\n\n\n<p>The activated mode depends on the signal being measured. Generally, real-time sampling works for all kinds of signals. Equivalent-time sampling (also called ETS) only works for stable, repetitive signals.<br><\/p>\n\n\n\n<p>Also, when it comes to sampling rates, you need to really double-check the specs. Some manufacturers emphasize good sampling rates in order to sell products, but they won\u2019t clarify whether the quoted rate applies to just repetitive signals (which would activate just the ETS) or <em>all <\/em>signals (which would activate both modes).&nbsp;<br><\/p>\n\n\n\n<p>You need to make sure the \u2018scope you\u2019re planning to purchase can handle the kind of signals you\u2019ll be working with.<br><\/p>\n\n\n\n<p>Analog oscilloscopes don\u2019t have a sampling rate. Since they already show waveforms as they are, they don\u2019t need to reconstruct the waves. Therefore, they don\u2019t need to sample them. If you don\u2019t want to worry about sampling rate, an analog model might suit you in this regard.<br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Memory Depth<\/strong><\/h3>\n\n\n\n<p>Memory depth works hand-in-hand with sampling rate. As we mentioned earlier, digital oscilloscopes convert the waveform into numbers by sampling it. Each time they do this, the data is stored in what is called a \u201cbuffer memory.\u201d&nbsp;<br><\/p>\n\n\n\n<p>The size of the buffer memory (or memory depth) determines how long a \u2018scope can capture a signal and convert it. If the memory depth is too small for the sampling rate, chances are you\u2019ll only get to use the \u2018scope at its full sampling rate a couple times before it hits its limit.<br><\/p>\n\n\n\n<p>You can read <a href=\"https:\/\/www.testandmeasurementtips.com\/memory-depth-and-sampling-rate-in-oscilloscopes\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">this article<\/a> for an extensive explanation of the relationship between memory depth and sampling rate which will help you further in answering your question; how do you buy an oscilloscope?<br><\/p>\n\n\n\n<p>You want to get a higher memory depth in order to get a solid, defined representation of the waveform reading. Again, a little research goes a long way.

We recommend the <a href=\"https:\/\/www.circuitspecialists.com\/hantek_2d72_oscilloscope_with_hard_case.html\">Hantek handheld oscilloscope<\/a>.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Handheld Hantek Oscilloscopes\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/YYVRi0wGcgI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><figcaption>Hantek Handheld Oscilloscopes<\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><em>Always <\/em>choose an oscilloscope with a bandwidth higher than the maximum frequency you plan to measure.
