The Keysight (Agilent) CX1105A Differential Sensor is a high-performance accessory for the CX3300 series Device Current Waveform Analyzer, delivering precise dynamic current measurements across a wide dynamic range. This differential sensor measures voltage across existing shunt resistors on test boards, converting those measurements into current waveforms within the CX3300 mainframe. The result is non-intrusive current profiling leveraging hardware already present in your test setup.
Designed for noise performance, the CX1105A captures current dynamics from 1 μA to 100 A with measurement bandwidth extending to 100 MHz. Engineers rely on this sensor for detailed power integrity analysis of Power Delivery Networks (PDN) across IoT, mobile, and automotive devices.
