10V 500mA PXI Source Measure Unit Sub Card Pulse PXI SMU Unit CBI401
The CBI401 modular subcard is a core component of the CS Series precision digital Source-Measure Units (SMUs), designed for medium-to-low power multi-channel electrical characterization. Featuring a single-card quad-channel common-ground architecture, each channel operates independently or synchronously, ideal for high-density parallel testing. Compatible with Pusces 1003CS (3-slot) and 1010CS (10-slot) hosts, it leverages a 3Gbps backplane bandwidth and 16-channel trigger bus to enable high-speed multi-device coordination. Optimized for low-noise, high-stability batch testing, it delivers up to 500mA current, 10V voltage, and 5W power per channel, addressing precision testing needs in semiconductors, sensors, and micro-power devices.
Product Features
▪ High-Density Multi-channel Design:Integrates 4 independent channels per subcard for parallel device testing.
▪ Synchronized Operation:Hardware-triggered synchronization across channels ensures μs-level timing accuracy.
▪ Precision & Low Noise:0.1% sourcing/measurement accuracy with 5½-digit resolution; current measurement down to 5μA, voltage range 10mV–10V.
▪ Four-Quadrant Operation:Simulates power supply or electronic load behavior in sourcing/sinking modes.
▪ Dual Mode Flexibility:Supports both pulsed and DC testing protocols for dynamic characterization.
▪ Scalable Architecture:Seamless integration with CS-series hosts for system expansion up to 40 channels.
