The 778572-54 is a state-of-the-art PXI Switch designed for versatile and high-frequency applications. Known by its model number PXI-2554, this device falls under the category of PXI RF Multiplexer Switch Modules, engineered to facilitate efficient signal routing in complex test setups.
It boasts a 4×1, high-frequency, unterminated multiplexing configuration, making it ideal for applications requiring rapid switching between signal paths without the need for termination. The PXI-2554 operates over a wide frequency range from DC to 2.5 GHz, ensuring compatibility with a broad spectrum of RF signals.
With a characteristic impedance of 75 Ohm, and a maximum voltage rating of 30 Vrms, this module is designed to handle significant signal levels while maintaining signal integrity. Furthermore, it supports a maximum switching current of 500 mA, providing ample capacity for most testing scenarios.
The insertion loss at 2.5 GHz is remarkably low, at less than 1.7 dB (with the common path being even lower, at less than 1.2 dB), ensuring minimal signal degradation. Similarly, the Voltage Standing Wave Ratio (VSWR) at 2.5 GHz is less than 1.75 (typically less than 1.5), which indicates excellent impedance matching and minimal signal reflection.
Utilizing electromechanical relays, the PXI-2554 provides reliable, repeatable switching with a minimum pulse width of 150 ns. It comprises 1 bank of 4 channels, enabling multi-path signal routing with ease.
For software integration, it supports NI-SWITCH, which is IVI-compliant, ensuring easy integration into automated test systems with minimal programming effort. This feature significantly enhances the module’s versatility, making it suitable for a wide range of applications in RF testing and signal routing.
