PXIe-4143 PXI Source Measure Unit National Instruments With 1A Output 4 SMU Channels 24V

The National Instruments PXIe-4143 PXI Source Measure Unit (SMU) integrates a versatile channel capable of delivering current or voltage with 16-bit setpoint and measurement resolution. This high-performance module combines source and measurement capabilities in a compact PXI Express form factor.

• Integrated tool channel with 16-bit resolution for precise current or voltage output
• Can provide up to 6 V and 1 A as supplementary power source
• Supports transistor characterization tests requiring constant current/voltage during scans
• Space-efficient solution with up to 17 modules in a single PXI chassis (17 SMU channels + 17 programmable power channels in 4U space)
• Dual-mode operation: constant voltage source or constant current source with adjustable compliance limits
• Remote sensing capability for improved measurement accuracy in high-precision applications
• Advanced measurement algorithms for different DUT impedance conditions

The PXIe-4143 SMU employs intelligent measurement strategies based on device characteristics. For low-resistance DUTs, it applies current stimulus followed by voltage response measurement. For high-impedance DUTs, it uses voltage stimulus followed by current response measurement.
