Description
The product with the part number 778572-94 falls under the category of PXI Switches, specifically the model PXI-2594. This model is a 4×1 High-Frequency, Unterminated, Multiplexing Switch, designed to operate over a wide frequency range from DC to 2.5 GHz. It is built to maintain a characteristic impedance of 50 Ohms, ensuring compatibility with standard RF systems.
The maximum voltage rating for this switch is 30 Vrms, with the ability to handle a maximum switching current of up to 500 mA. One of the key features of the PXI-2594 is its low insertion loss, which minimizes signal degradation, and it offers an excellent Voltage Standing-Wave Ratio (VSWR), which indicates efficient signal transmission through the switch.
Furthermore, the switch boasts high isolation between its ports, significantly reducing signal crosstalk and ensuring that signals are routed cleanly and efficiently. Relay count tracking is supported by the device, providing valuable information for maintenance and system debugging.
For applications requiring fast switching, the PXI-2594 can recognize trigger pulse widths as narrow as < 150ns when digital filtering is disabled. This feature is essential for high-speed test and measurement tasks. The path resistance for this switch is defined by the sum of contact resistance and trace resistance, which ensures the device’s performance aligns with its specified capabilities. Towards the end of its life, the contact resistance remains higher than 1.0, indicating the switch’s durability and long-term reliability.
