PC USB or Virtual oscilloscopes are based on high-performance modular hardware, combined with efficient and flexible software to complete various testing, measurement, and automation applications.

PC USB or Virtual oscilloscopes also have the characteristics of waveform triggering, storage, display, measurement, and waveform data analysis and processing. However, it should be noted that due to the significant performance differences between virtual oscilloscopes and analog oscilloscopes, improper use may result in significant measurement errors.
