701977 Differential Probe 7000 V / 50 MHz

The box part of 701977 is smaller than the conventional model. This saves space when measuring multiple channels such as inverter measurement. 701977 has a shape that is easy to tie up and put together.

701977 Differential probe for Oscilloscope Applications:

• 3.3 kV level railway drive inverter measurement

• High voltage, low frequency IGBT measurement

• High voltage surge noise waveform measurement

What is a high voltage differential probe?

High voltage differential probes are for floating high voltage signal measurement with oscilloscopes in the power electronics and mechatronics fields.
