      25 MHz 1400 V differential oscilloscope probe 20:1/200:1

      The TA057 is a 25 MHz bandwidth active differential probe suitable for high common-mode voltage measurement applications up to ±1400 V (DC + peak AC).

      This differential probe extends the capability 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.
