A high voltage differential probe is used for measuring the voltage difference between two test points where neither test point is at ground. High voltage differential probes from Tektronix can be used for signals up to 6000 V. These probes are the best choice for making non-ground referenced, floating or isolated measurements in large part due to their common mode rejection capability.
The THDP0200 is an active differential probe that is capable of safely measuring differential voltages up to ±1500 V. The probe is effective in making measurements in IGBT circuits such as motor drives and power converters.
The THDP0200 supports bandwidths up to 200 MHz and slew rates up to 275 V/ns at 1/250 gain.
