The Pico Technology TA044 oscilloscope probe is an active differential probe, suitable for high common-mode voltage measurement applications up to ±7000V. It can be used with a signal speed of up to 70Hz. 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 1:100, this oscilloscope probe can measure signals below 70V to get higher resolution and less noise. Otherwise, set the attenuation to 1:1000.
