PXIE-4144

The PXIe‑4144 is a 4‑channel, four‑quadrant high‑speed Source Measure Unit (SMU) in a 3U single‑slot PXIe form factor. It delivers ±6 V and up to ±500 mA per channel, with 150 pA current sensitivity and 3 W sink power per channelNI. Optimized for high‑pin‑count, parallel, and fast IV characterization, it combines high current drive, moderate voltage, and picoamp‑level measurement performance for semiconductors, PMICs, and low‑leakage devicesNI.

Usage and Maintenance

Installation

Insert into a 3U PXIe slot, secure the latch, and connect 4‑wire sense/guard cables for low‑current measurements. Power on; the system auto‑recognizes the module. Use NI‑MAX to set limits, enable remote sense, and configure triggersNI.

Operation

Warm up 30 minutes before high‑precision tests. Operate within rated voltage, current, and power. Use SourceAdapt presets to optimize transient response for your loadNI.

Maintenance

Keep the module clean, dry, and ventilated. Avoid excessive force on connectors. Inspect cables periodically for wear. Calibrate annually to maintain accuracy. Store with ESD protection when not in useNI.
