USB oscilloscopes are are becoming increasingly popular. Nevertheless there is a wide range of instruments available starting from less than one hundred up to several thousands of dollars. The following comparison chart provides a list of products with some important selection criteria. The list covers products in the low-end price range from 100 to 500 USD and with a bandwidth of at least 50 MHz. Most of USB PC scopes are pure digital oscilloscopes (DSO) but some offer also mixed-signal functions (MSO) or even additional features such as arbitrary waveform generator (AWG), logic analyzer, protocol analyzer or spectrum analyzer.
Please do not compare only hardware features but also the software. The software plays an important role in the overall functionality and usability of an USB oscilloscopes. Unfortunately software is difficult to be expressed in hard figures and therefore difficult to compare.
