National Instruments PXI-2594 PXI RF Multiplexer Switch Module

The NI PXI-2594 (Part Number: 778572-94) is a 4x1 high-frequency, unterminated, multiplexing switch, ideal for switching signals from DC to 2.5 GHz. The characteristic impedance of the channels on this module is 50 Ohms. The NI PXI-2594 has a maximum voltage rating of 30 Vrms with a maximum switching current of 500 mA. It is appropriate for applications that require the routing of high-recurrence signals inside automated test equipment (ATE) frameworks, since it can switch signals with low insertion loss. In addition, the fantastic voltage standing-wave ratio (VSWR) and isolation parameters make this module the ideal choice in any framework intended for high-recurrence applications. The PXI-2594 also offers relay count tracking to help decrease unexpected framework downtime.

The transmission capacity of a switch module is not an absolute specification and is dictated by seller measures. Although higher recurrence signals can be directed through this switch module, they will experience more corruption than those at lower frequencies. With a specific end goal to decide the best switch module for the user’s application, review the insertion loss, VSWR, and isolation specifications of the item for the data transmission of the application.

Path resistance is a mix of relay contact resistance and trace resistance. Contact resistance regularly stays low for the life of the relay. Toward the end of the relay life, the contact resistance transcends 1.0. The NI PXI-2594 RF Multiplexer Switch Module can also perceive trigger pulse widths under 150ns by disabling digital filtering.
