The Pico Technology TA057 oscilloscope probe is an active differential probe, suitable for high common-mode voltage measurement applications up to ±1400V. It can be used with a signal speed of up to 25MHz. 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.
