Aside from the multimeter, an oscilloscope is one of the most important tools on any electronics engineer’s bench. It allows them to visualize and analyze a wide range of analog and digital signals, which is necessary for troubleshooting, debugging, and testing circuits. However, the many options available can be overwhelming to a new user, so we’ve put together this guide to help you find the best oscilloscope for your needs.
The first thing you’ll need to decide when selecting an oscilloscope is what frequency range it can handle. Choosing a scope with a higher bandwidth will ensure that it can accurately measure high-frequency signals. It’s also worth considering whether the signal you need to test is periodic or non-periodic. A periodic signal will require a higher sample rate, while a non-periodic signal will need a lower sample rate.
Choosing the Right Tool: Navigating the Maze to Find the Best Oscilloscope for Your Needs
Once you’ve decided on the frequency range, the next thing to consider is what channel count you need. A simple scope will typically have two channels, which is sufficient for most applications. For more advanced needs, however, you may need more channels, which can be achieved by purchasing a model with expandability.
Other important features to look for include the rise time and memory depth of the oscilloscope. The rise time is the amount of time it takes for a signal to go from low to high, and a higher rise time will allow you to see more detail in your waveforms. The memory depth is how much data the scope can store, and a larger memory depth will allow you to capture longer signals or more complicated data streams.
