Pico TA041 - 25 MHz, 700 V Differential Oscilloscope Probe The TA041 is an active differential probe suitable for high common-mode voltage measurement applications up to ±700 V (DC + peak AC). It can be used with signal speeds of up to 25 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.The TA041 is an active probe and therefore requires power to function. Four AA batteries are included as standard. Not included as standard but available as optional extras, the PS008 power supply and TA059 Probus power adapter are also available to purchase.
