The NI PXI-2594 is a high-frequency, 4×1 unterminated multiplexing switch module with a frequency range from DC to 2.5 GHz, characteristic impedance of 50 Ohms, and can handle a maximum voltage
The NI PXI-2594 is a PXI RF Multiplexer Switch Module with a part number 778572-94, designed as a 4×1 high-frequency, unterminated, multiplexing switch that operates within a frequency range from DC to 2.5 GHz. Its characteristic impedance is set at 50 Ohms, and it can handle a maximum voltage rating of 30 Vrms and a maximum switching current of 500 mA.
For detailed specifications on insertion loss, VSWR (Voltage Standing Wave Ratio), and isolation, it is recommended to refer to the manufacturer’s datasheet. The module supports relay count tracking and is capable of recognizing trigger pulse widths under 150ns when digital filtering is disabled. Path resistance is a combination of relay contact resistance and trace resistance, which typically remains low throughout the life of the relay. However, at the end of the relay’s life, contact resistance may exceed 1.0 Ohm.
