Agilent/Keysight CX1205A

The Keysight CX1205A is a sensor head adapter that extends the current measurement capabilities of the CX3300 series Device Current Waveform Analyzer. This test lead adapter connects directly to DUT test points via two mini-jack terminals linked to the analyzer's ammeter channels through an integrated current sensor. The included five test leads facilitate convenient connection to mini-plug test points on the device under test or its associated test board, enabling direct current measurement across a wide dynamic range.
