PXIE-2543

The PXIe‑2543 (part number 780587‑43) is a high‑speed, solid‑state dual 4×1 (dual SP4T) RF multiplexer module designed for the PXI Express platform. Supporting frequencies from 10 MHz up to 6.6 GHz, it provides two independent 4‑to‑1 signal routing banks with 50 Ω impedance and full termination on all channels and common lines. Built with FET‑based solid‑state relays, it delivers unlimited relay life, ultra‑fast switching, and consistent RF performance for high‑throughput automated test systems, especially in semiconductor, wireless, and microwave applications.

Usage and Maintenance Instructions

Installation and Configuration

Insert the module into a 3U PXIe chassis slot and secure the latch. Connect RF cables to SMA ports (CH A/B and COM) and trigger cables to SMB connectors if needed. Power on the chassis; the system auto‑detects the module. Use NI‑MAX to set up channel routing and trigger parameters. Develop test programs in LabVIEW/C++ using the NI‑SWITCH driver to implement automated switching sequences.

Daily Maintenance

Operate in a clean, dry, ESD‑protected environment within rated temperature limits. Avoid over‑torquing SMA connectors to prevent damage to contacts. Inspect cables and connectors periodically for wear or contamination. Ensure adequate chassis cooling during extended operation. When unused, power off, disconnect cables, and store in a dry ESD bag.

Safety Notice

Do not exceed ±8 V DC or +30 dBm RF power ratings to avoid permanent damage. Follow ESD protocols when handling the module. Disconnect all power before installation or removal. Use only 50 Ω SMA cables rated for 6.6 GHz. Dispose of the module per local electronic waste regulations at end‑of‑life.
