• Pico 25MHz 1400V Differential Probe TA057, 20:1/200:1. Pico TA057 is 25MHz bandwidth active differential probe suitable for high common-mode voltage measurement applications up to ±1400V (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 TA057 is suitable for measuring transients in switching power supplies, inverters and motor drives, electronic ballasts and CRT displays, as well as signals in the millivolt range from sensors and other instrumentation. The differential inputs make it possible to measure voltages on floating circuits.
