Velleman PCSGU250: USB-PC Scope and Generator

Velleman PCSGU250

The Velleman PCSGU250 Two-Channel USB-Powered Oscilloscope and Function Generator

The Velleman PCSGU250 is a multi-function unit complete with USB powered oscilloscope and generator. With the PCSGU250, there’s no need for multiple test units that consume your work space. This complete USB-powered lab-in-a-box contains pclab2000-lt software for a channel oscilloscope and recorder, spectrum analyzer, function generator, and bode plotter. Create your own waveforms using the integrated signal wave editor. It’s even possible to generate wave sequences using a file or computer rs232 input for automated measurements.


The Velleman PCSGU250 makes for the perfect hobbyist oscilloscope and gets you the best value for your dollar. Your order comes with a "getting started" manual, a USB cable, and the software on a CD. You will also get a scope probe (the PROBE60s) and a BNC male to female adaptor (CBNC15).
