How to find the right USB oscilloscope?
USB oscilloscopes - just like benchtop instruments - also have analog and digital channels. Decisive for the selection of a USB oscilloscope is the number of channels, which defines how many different signal sources can be acquired in parallel. Some USB oscilloscopes also have additional functions such as spectrum analyzers and function generators.
As with all other oscilloscopes, essential criteria for USB devices include bandwidth, sampling rate, memory depth, and available software when making a selection.
Although USB oscilloscopes are so small, they also need to be calibrated and certified regularly.
