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 powered by either four AA batteries, included, or the PS008 power supply, available as an optional extra.
