The PMK Fast-Edge USB Genarator is a fast signal generator that delivers a square pulse of ~ 32 ps in a USB stick size. The one-button operation enables the selection of different operating modes. The output signal with -500 mV and 50 Ohm is very square and flat, without overshoot or undershoot. This is perfect for checking the rise / fall times of instruments and probes, as well as checking the rise / fall times and signal violations of signal paths.
