The Micsig DP10007 comes from the recent series of cost effective differential probes of Micsig. With this probe, you can use your conventional earth-grounded oscilloscope to measure floating signals of up to 700 V of differential and common-mode voltage in 100:1 mode. It comes in handy when designing power supplies, motor drivers and and when working with electronic ballasts. The probe allows you to confidently perform measurements on mains electricity without damaging the scope thanks to its high voltage rating.
The probe is simply powered by USB, a common interface on all modern oscilloscopes and computers. This makes the probe a very portable tool and removes the need of a dedicated adapter brick.
