Product Information
Pico 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.
The TA043 is an active probe powered by either four AA batteries, included, or the TA531 USB to DC Jack power lead, also included as standard. The TA531 is intended for use with generic USB wall chargers (not included).
