Description
The 778572-48 is a high-performance PXI Switch designated as model PXI-2548. It is designed as a General-Purpose Switching Module that offers versatility for a wide range of switching needs. This module boasts a Single-Pole, Double-Throw (SPDT), independent relay configuration, allowing for flexible connectivity options.
One of the key technical specifications of the PXI-2548 is its Resistance Control Resolution, which goes down to 0.25 Ω, providing precise control over resistance settings. The module’s connectivity is facilitated through a 37-pin D-SUB connector located on the front panel and 2×2 Micro-Fit connectors, ensuring easy integration into various setups.
With a bandwidth capability of up to 2.7 GHz, this module is suitable for applications requiring high-frequency performance. The Insertion Loss at 2.7 GHz is less than 1.0 dB, with a typical value being less than 0.7 dB, indicating minimal signal degradation. Additionally, the VSWR at 2.7 GHz is less than 1.7, with a typical value being less than 1.5, demonstrating excellent voltage standing wave ratio performance.
An important feature of the PXI-2548 is its Onboard Relay Counting capability, which aids in monitoring and managing the operational lifespan of the module’s relays. This feature adds to the module’s reliability and maintenance ease, making it a valuable asset for any testing and measurement setup requiring general-purpose switching with high-performance characteristics.
