The Pico Technology TA041 oscilloscope probe is an active differential probe, suitable for high common-mode voltage measurement applications up to ±700V. It can be used with a signal speed of up to 25Hz. 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.

By selecting attenuation ratio 1:10, this oscilloscope probe can measure signals below 70 V to get higher resolution and less noise. Or else, set the attenuation to 1:100.
