The Keysight CX1104A is a selectable shunt current sensor for dynamic current measurements in the CX3300 series device current waveform analyzers. It delivers low-noise current sensing from 1 μA to 15 A across a 20 MHz bandwidth, with flat frequency response and no derating. The sensor integrates calibrated resistive sensor heads (CX1211A through CX1216A) that provide insertion resistance values from 5.5 mΩ to 1 Ω, minimizing measurement loading. A common mode voltage range of ±40 V accommodates diverse test environments. The included banana adapter supports high-current connectivity, while calibrated sensor head operation ensures measurement accuracy for dynamic waveform capture.
