PXIE-4154

The PXIe‑4154 is a 2‑channel, two‑quadrant battery and charger simulator in a 3U two‑slot PXIe form factor. It integrates a 6 V/3 A battery simulation channel (Ch0) and an 8 V/1.5 A charger simulation channel (Ch1), with 1 µA current sensitivity and <20 µs transient responseNI. Designed for RF and wireless device testing, it accurately emulates lithium‑ion battery characteristics including fast load transient, programmable internal resistance, and bidirectional source/sink for portable electronics, RF power amplifiers, and mobile handsetsNI.

Usage and Maintenance Instructions

Installation

Insert the module into two adjacent 3U PXIe slots and secure the latches. Connect 4‑wire force/sense cables to the front‑panel connectors, ensuring correct polarity for battery/charger channels. Power on the chassis; the system auto‑recognizes the module. Use NI‑MAX to configure voltage/current limits, enable remote sense, and set transient response modes.

Operation

Warm up 30 minutes before precision testing. Operate each channel within its rated voltage, current, and power limits. For battery simulation, adjust output resistance to match the DUT’s battery characteristics. Use fast transient mode for RF devices to minimize voltage fluctuations.

Maintenance

Keep the module clean, dry, and adequately ventilated. Avoid excessive force on front‑panel connectors. Inspect cables and connections periodically for wear or damage. Calibrate annually to maintain specified accuracy. Store in an ESD‑protected environment when not in use.
