200/2000 A AC/DC current probe, D9 connector

The TA301 is a high-bandwidth, high-current probe fitted with a D9 connector specifically designed to work with the PicoScope 4444 differential oscilloscope. The probe is automatically sensed by the PicoScope 4444 oscilloscope and features two current ranges: 200 A and 2000 A, AC or DC. The range is selected in the PicoScope 6 software, which also sets the probe range and vertical axis scaling.

A current clamp is shown with cable coiled up, showing D9 connector on a white background
