PXI-2544

Description

The National Instruments PXI-2544 (Part Number: 778572-44) is a high-performance, terminated 8×1 Multiplexer Switch Module designed for use in RF signal routing up to 6.6 GHz. This module is equipped with solid-state relays for rapid switching and features front-mounted SMA connectors for straightforward integration into test setups.

Each COM line and channel is terminated to maintain a 50 Ohm impedance, thereby minimizing signal reflections and preserving the integrity of the RF signals. The bandwidth specification of the module is dynamic and varies with frequency, indicating that while higher frequency signals can be routed, they may experience more degradation compared to those at lower frequencies.

Users are advised to consult the module’s specifications for detailed information on insertion loss, VSWR (Voltage Standing Wave Ratio), and isolation to ensure compatibility with their specific application requirements. The NI PXI-2544 leverages the PXI platform’s inherent timing and synchronization capabilities to facilitate communication with other instruments within the chassis.

With onboard memory for storing switch connections and an integrated hardware scanning and triggering engine, this module streamlines the process of sequence execution, thereby reducing software overhead and bus latency for faster and more repeatable test execution.
