The Agilent/Keysight CX1102A is a dual-channel current sensor module for the Keysight CX3300 series mainframe, engineered for high-fidelity characterization of dynamic current consumption in low-power wireless devices and microcontrollers. The synchronized two-channel architecture delivers a 100x range difference between channels, enabling simultaneous observation of waveforms across a broad dynamic range—critical for detecting subtle current transitions during sleep/standby and active state switching. Wideband noise suppression preserves measurement integrity at low current levels while maintaining minimal input resistance.

• Applications demanding simultaneous observation of large and small current excursions
– Compatibility & Integration
The CX1102A requires a Keysight CX3300 series Device Current Waveform Analyzer mainframe (CX3322A or CX3324A) for operation. The module occupies dual channels within the host mainframe and derives all timing synchronization and display control from the CX3300 platform.
