The NI PXI-2594 is a 4x1 high-frequency, unterminated, multiplexing switch module, ideally suited for routing signals from DC to 2.5 GHz, with a characteristic impedance of 50 ohms on its channels.
Here is a detailed introduction in English:
Features
High Frequency Switching: It can switch signals with low insertion loss, making it suitable for applications that require the routing of high-frequency signals within automated test equipment (ATE) systems.
Excellent Signal Integrity: The module features excellent voltage standing-wave ratio (VSWR) and isolation parameters, which help to minimize signal degradation.
Relay Count Tracking: The PXI-2594 offers relay count tracking, which can be used to predict relay lifetime and reduce unexpected system downtime.
Wide Voltage and Current Ratings: The module has a maximum voltage rating of 30 VRMS and a maximum switching current of 500 mA.
Small Size and Light Weight: The PXI-2594 is a compact and lightweight module, measuring 8.5 x 0.8 x 5.1 inches and weighing 6.95 oz.
