NI PXI‑4130 (referred to as NI‑4130)

Model: PXI‑4130 | Type: 3U PXI source measurement unit (SMU) + auxiliary power channel | Status: Active, mainstream high-precision DC test module PXI-4130

I. Basic Specification

Full Name: NI PXI‑4130 Source Measure Unit (SMU)

Form: Single-slot 3U PXI module, integrating two output channels:

Channel 1 (SMU main channel): Four-quadrant, isolated SMU (source / sink current, capable of measuring voltage / current)

Channel 0 (Utility auxiliary channel): Single-quadrant low-cost power supply

Application: Semiconductor / component characterization, LEDs, batteries, sensors, precise DC testing, IV curves, reliability aging

Core Advantages: ±20 V / 2 A, 40 W source, 10 W sink, nA level measurement, 4-wire remote sensing, isolated output
