5 GHz 4x1 and Quad 4x1 Multiplexers

Overview

The National Instruments PXI-2595 and SCXI-1195 are 4x1 high-

frequency, unterminated multiplexing switches. The NI SCXI-1195

performs the same functions as the PXI-2595 but in a higher density,

quad 4x1 multiplexing configuration. The PXI-2595 and SCXI-1195 are

capable of switching signals from DC to 5 GHz. The characteristic

impedance of these modules is 50

Ω.

The PXI-2595 and SCXI-1195 have a maximum voltage rating of

well-suited for applications that require the routing of high-frequency

signals inside automated test equipment (ATE) systems because they

can switch signals with very low insertion loss. In addition, the excellent

voltage standing-wave ratio (VSWR) and isolation parameters make

these modules the perfect choice in any system that is geared toward

high-frequency applications

Relay Count Tracking

The PXI-2595 and SCXI-1195 count relay closures on each of their

RF relays. Relay counts are incremented each time a relay is

actuated. The counts, stored on board the module, are retrievable

programmatically, and you can use them for predictive maintenance

to reduce unexpected system downtime.

Software

All National Instruments PXI and SCXI switch modules are shipped with

NI-SWITCH, an IVI-compliant driver offering complete functionality

for all switch modules. For additional assistance in configuring,

programming, and managing higher-channel-count switching systems,

NI Switch Executive software offers an easy-to-use, intelligent switch

management and visual routing environment. Use the NI-SWITCH

soft front panel for simple relay operations or debugging switch

code/execution.
