Overview

Product overview

Key product information and technical features.

The PXIe-2542 provides four banks of solid-state SPDT RF switching in a PXI Express module. Its 6.6 GHz bandwidth and 50 Ω signal paths support RF signal routing in production test systems.

Front-mounted SMA connectors provide access to the RF paths. Termination on every COM line and channel helps minimize reflections when routing signals between RF devices and test instruments.

Quad 2 × 1 topology with four SPDT banks and FET switching.
6.6 GHz switch bandwidth with 50 Ω characteristic impedance.
50 Ω termination on every COM line and channel.
Scan rate of 8000 cycles/s.
Front-mounted SMA connectors for RF connections.
