National Instruments PXI-2596 PXI RF Multiplexer Switch Module

The National Instruments PXI-2596 (Part Number: 778572-96, 193271D-01L) is a multiplexer, SPDT relay, and transfer switch module intended for routing RF or microwave signals in automated test applications. The PXI-2596 offers 26.5 GHz switching in various PXI arrangements for an entire switching solution on one platform. Utilizing microwave relays from Radiall, the module is intended to work with under 1 dB insertion loss up to 26.5 GHz, limiting effects on the test framework and showing up relatively imperceptible to signals at much lower frequencies. This module is perfect for passing high-order harmonics from RF upconverters, such as the NI PXI-5671 2.7 GHz vector signal generator or directing different sources to RF downconverters like the NI PXI-5660 2.7 GHz vector signal analyzer.

To configure and control the NI PXI-2596 RF Multiplexer Switch Module, engineers can utilize NI Switch Executive 2.1, which presents a few new highlights for Excel, RF switching, and switch framework troubleshooting. The updated software gives engineers automatic access to settings on a per-switch route basis, so they can store RF path calibration and parametric data, enhancing general test framework exactness.

With the new configuration programming interface, specialists can determine and arrange their NI Switch Executive virtual gadget from any programming condition, including NI TestStand test management software, the NI LabVIEW graphical development condition, NI LabWindows/CVI ANSI C development software, and Microsoft Excel. With this new usefulness, specialists can import existing switch route records made in Excel into the NI Switch Executive environment, making them simpler to keep up and adjust.

The physical dimensions of the 2 Slot, 3U PXI-2596 measure 8.5 in. × 1.6 in. × 5.1 in. (21.6 cm × 4.1 cm × 13.0 cm). Constructed from gold-plated beryllium copper, the switch module weighs 13.8 oz (391 g). The PXI power requirements for the device is 2.5 W at 3.3 V, 1 W at 5 V, and 6 W at 12 V.
