Description: Turn your computer into an oscilloscope with the Velleman PCSU01: Mini USB Oscilloscope for Windows PCs. This portable scope is quick and easy to use. Just plug it into your Windows XP, Vista, 7, 8 and 10 computer via USB and install our custom software to use your PC as an oscilloscope.

This pocket sized scope includes test leads and has three separate functions — oscilloscope, spectrum analyzer and transient recorder. In the oscilloscope module, use the PCSU01 as a digital storage oscilloscope to analyze voltage over time and display the data in waveform graphs. The spectrum analyzer allows you to visualize the frequency spectrum of a signal using FFT (Fast Fourier Transform) analysis. Use the transient recorder to record events and log slow changing processes such as temperature and battery charge cycles.
