Best Oscilloscopes Under $500

Best Oscilloscopes Under $500 [2023 Buying Guide]

Oscilloscopes are an electronic measuring device that allows you to measure and record an electrical signal over time. They are an essential instrument in electrical and electronic engineering. An oscilloscope allows an engineer to analyze various details of a signal’s waveform, including, its shape, amplitude, and frequency. If you’re in the market for an shiny new oscilloscope, you’ve come to the right place! In this article we’ll be reviewing the best oscilloscopes under $500 available on Amazon.

Whether you are electronic hobbyist, student, or even a professional engineer, choosing the right oscilloscope to fit your needs can be quite difficult due to its varying costs and features. This is why, in this buying guide, we will discuss our top picks and cover all the important aspects of choosing the right oscilloscope for you.

Before we begin, let’s discuss some key factors to consider when choosing an oscilloscope.

Factors to Consider When Choosing an Oscilloscope

Analog vs Digital

Most of the affordable oscilloscopes today and most of the best oscilloscopes under $500 are digital. Nowadays, however, digital oscilloscope today is pretty accurate in emulating the accuracy of analog scopes and can offer additional features like portability (analog scopes are generally bigger and heavier), colored digital display, single-shot ability, higher average bandwidth, and so on.


The bandwidth of an oscilloscope system dictates the maximum frequency that the instrument can accurately measure. The higher the bandwidth, the more expensive the oscilloscopes will be.

In general:

  • If it’s an analog oscilloscope, get bandwidth at least 3 times higher than the highest frequency (sine wave) you want to measure
  • If it’s a digital oscilloscope, choose a bandwidth at least 5 times the highest clock rate in the system

Sample Rate

The sample rate of the oscilloscope determines how detailed the waveform can be displayed in a digital oscilloscope. Commonly measured in MS/sec or GS/sec, MS stands for mega (1 thousand) sample and GS stands for giga (1 million) sample. In general, you should aim for a sampling rate that is 2 times bigger than the max frequency we are willing to measure.

Memory Depth

Memory depth is essentially calculated by multiplying the sample rate with time across the display. An oscilloscope capture sample points in its memory and the amount of memory will determine how long the oscilloscope can store the signal before it must dump or delete it.

Type of Probes

The oscilloscope can be divided into two parts: the scope and the probe. In most cases, we usually pay more attention to the scope but don’t really consider the probe. Different scopes might only be compatible with certain types of scopes, and here are some common types you can consider:

  • Passive probes: included with most oscilloscopes, suitable for most ground-referenced measurements
  • High-voltage differential probes: useful to take safe, accurate differential and floating measurements
  • Logic probes: used to deliver digital signals to mixed-signal oscilloscopes.
  • Current probes: used to measure current—as the name suggests—- and can also enable the oscilloscope to measure changes in power

Ease of Use

Here are some factors that might determine how intuitive and easy to use an oscilloscope is:

  • The built-in help menu, so we don’t need to read a separate manual
  • Larger display and the ability to zoom/amplify the waveform, so we can view waveforms and measurement data at the same time
  • How easy it is to control the oscilloscope including features like larger knobs and voice control
