Use the Pico TA057 Differential Probe (x20/x200 25MHz 1400V CATIII) to view live measurements from any pair of windings on a 3-phase system, such as those used in hybrid vehicles.

To view all 3 pairs of windings at the same time on a 3-phase, you need 3 differential probes and a scope with 3 or more channels, such as the Pico 4423, 4425,4425a.

The Pico TA057 Differential Probe is an active probe, it can be used with standard grounded oscilloscopes to measure signals that are not referenced to ground. The built in amplifier scales and converts the high voltage differential input to a low, voltage single-ended BNC output.
