Oscilloscopes
Accessories
The TA043 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 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.
