The Keysight CX1215A is a resistive sensor head engineered for precision current measurement within the Keysight CX1104A selectable shunt current sensor ecosystem. This component delivers dynamic current measurements up to 2 A across a 20 MHz bandwidth, with typical insertion resistance of 103 mΩ including the calibrated shunt resistor. The CX1215A combines low-impedance signal conditioning with high-frequency response, making it suitable for fast transient current characterization in laboratory and field test environments.

– Compatibility & Integration
The CX1215A operates exclusively with the Keysight CX1104A selectable shunt current sensor. This pairing integrates into broader test and measurement systems requiring precision current data acquisition. Connection to external measurement instruments occurs through the CX1104A’s banana adapter interface, supporting standard banana cable connectivity. When sensor performance issues arise, field-swappable replacements from the CX1211A through CX1216A family allow rapid isolation of hardware faults without major system reconfiguration.
