The TA042 is an active differential probe suitable for high common-mode voltage measurement applications up to ±1400 V (DC + peak AC).
It is capable of acquiring higher speed signals of up to 100 MHz.
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.
