Description
The Part Number 778572-94 refers to a highly sophisticated PXI Switch, specifically the PXI-2594 model. This model is a product of National Instruments and is known as the National Instruments PXI-2594 PXI RF Multiplexer Switch Module. The device is designed with a 4×1 Multiplexer configuration, making it versatile for various applications.
It operates over a frequency range from DC to 2.5 GHz and is built to handle a maximum voltage rating of 30 Vrms. The module is designed to support a maximum switching current of 500 mA, ensuring reliable performance for high-demand applications. Its characteristic impedance is 50 Ohms, which is standard for RF applications, providing consistent signal integrity.
One of the key features of the PXI-2594 is its low insertion loss and excellent Voltage Standing Wave Ratio (VSWR), which are critical for maintaining signal quality. Additionally, it boasts high isolation levels, further enhancing its performance by minimizing crosstalk and signal leakage between channels.
The device supports relay count tracking, a feature that enables users to monitor the operational lifespan of the relays within the module. This is particularly important for predictive maintenance and ensuring the reliability of the system. The contact resistance at the end of relay life is guaranteed to be greater than 1.0, indicating the module’s durability and long-term performance capabilities. Furthermore, it can recognize a trigger pulse width of less than 150ns (with digital filtering disabled), which allows for rapid signal switching, making it suitable for high-speed applications.
In conclusion, the National Instruments PXI-2594 PXI RF Multiplexer Switch Module is a highly reliable, efficient, and versatile tool for a wide range of RF switching applications. Its technical specifications ensure it meets the needs of demanding environments, offering low insertion loss, excellent VSWR, high isolation, and fast switching capabilities.
