70 MHz 7000 V differential oscilloscope probe 100:1/1000:1

The TA044 is an active differential probe suitable for high common-mode voltage measurement applications up to ±7000 V (DC + peak AC).

This differential probe extends the functionality of standard single-ended input oscilloscopes to allow a safe and accurate method of making high-voltage differential measurements. Applications include making safe measurements in power circuit applications and acquisition of low-speed balanced differential signals found in serial communications buses.

Note: The spring hooks supplied with this probe are rated at 1000 V.
