National Instruments PXI-255x 2.5 GHz 75 Ω Multiplexer and SPDT Relay Switch Modules

  • 2.5 GHz Bandwidth
  • 75 Ω Characteristic Impedance
  • 30 V Max Switching Voltage
  • 0.5 A Max Switching Current
  • 10 W Max Switching Power
  • Mini SMB Direct Connectivity


The National Instruments PXI-255x 2.5 GHz Multiplexers and SPDT Relay Switch Modules are ideal for routing video RF signals in automated test applications, such as the testing of video set-top boxes. All modules are designed to have minimum insertion loss and voltage standing-wave ratio (VSWR) specifications to reduce signal reflections and losses in the transmission line, thereby maintaining signal integrity.

The NI PXI-2555 multiplexer and PXI-2559 SPDT relay modules provide 75 Ω terminations for applications where high-power signal reflections could damage the source. The PXI-2554, PXI-2546, PXI-2547, and PXI-2548 are low and high-channel-count multiplexers and SPDT relay switch modules ideal for building dense switch networks in a single PXI chassis.

All modules are suited for use with any third-party RF analyzer, generator, or device under test (DUT) that has a characteristic impedance of 75.

All modules count relay closures on each RF relay. You can programmatically retrieve the counts, which are stored on board the module itself, and use them for predictive maintenance to reduce unexpected system downtime.

Product Family: PXI-255x, PXI-2554, PXI-2555, PXI-2556, PXI-2557, PXI-2558, PXI-2559, PXI 255x, PXI 2554, PXI 2555, PXI 2556, PXI 2557, PXI 2558, PXI 2559, PXI255x, PXI2554, PXI2555, PXI2556, PXI2557, PXI2558, PXI2559

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
