Pico TA045 is a 200MHz bandwidth active differential probe suitable for high-speed measurement applications with a differential measurement range of ±20V and a common-mode range of up to ±60V (DC + peak AC). 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. The TA045 is optimised for small-signal applications such as telecom measurement, xDSL, high-speed power measurement and differential transmitter and receiver design.
