Product Information
The Pico TA057 is a 25 MHz bandwidth active differential probe suitable for high common-mode voltage measurement applications up to ±1400 V (DC + peak AC).
This differential probe extends the capability 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 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).
