PXIe-2540

The PXIe-2540 is a PXI RF Matrix Switch Module from National Instruments, designed for RF signal routing, automated test systems, signal path selection, and modular PXI Express measurement platforms. As a 350 MHz, 8×9 PXI RF matrix switch module, the NI PXIe-2540 allows users to route signals between multiple rows and columns within a flexible switching matrix. NI lists the PXIe-2540 with part number 780587-40.

The NI PXIe-2540 is useful for engineers who need to route multiple signals between instruments and devices under test in an automated PXI system. It can be used to connect digitizers, function generators, RF generators, analyzers, test fixtures, and other measurement devices. Compared with manual signal switching, the PXIe-2540 allows signal paths to be controlled through software, making it suitable for repeatable test sequences, laboratory automation, and production testing.

One of the main advantages of the PXIe-2540 RF Matrix Switch Module is its 8×9 non-blocking matrix topology. With a non-blocking design, users can simultaneously connect any row or column within the switching matrix, improving flexibility when building automated signal routing systems. This makes the PXIe-2540 suitable for applications that require multiple instruments to be connected to multiple test points or devices under test.

The National Instruments PXIe-2540 supports RF signal routing up to 350 MHz. This bandwidth is useful for routing signals between digitizers, function generators, RF generators, and RF analyzers. The module also uses isolation relays to disconnect unused parts of the matrix, helping maintain RF performance and high isolation during operation.

The PXIe-2540 is especially suitable for systems where users need flexible signal path control rather than a simple multiplexer topology. Engineers can use it to build custom switch networks, automate signal routing between multiple test instruments, connect several devices under test to shared measurement equipment, or reduce manual cable changes during validation and production testing.

Technical listings describe the NI PXIe-2540 as supporting up to 10 W switching power, 60 VDC switching voltage, and up to 0.5 A maximum carry current per channel. These specifications help engineers evaluate whether the module is suitable for their signal level, switching configuration, and test system requirements.

In system integration, the PXIe-2540 PXI RF Matrix Switch Module installs into a compatible PXI Express chassis and can be used with digitizers, function generators, RF signal generators, RF analyzers, source measure units, DAQ modules, and other PXI/PXIe instruments. This allows engineers to build compact, software-controlled switching systems for automated measurement and validation platforms.

The PXIe-2540 is suitable for applications such as RF signal routing, automated test signal switching, matrix signal routing, instrument sharing, device validation, functional testing, laboratory automation, and production test systems. Its 8×9 matrix architecture is especially useful when multiple signals need to be routed flexibly between several instruments and test points.

Overall, the NI PXIe-2540 PXI RF Matrix Switch Module is a flexible signal routing solution for PXI Express automated test systems. With its 350 MHz bandwidth, 8×9 non-blocking matrix topology, isolation relays, software-controlled switching, and PXI Express platform compatibility, the PXIe-2540 is well suited for RF signal routing, automated validation, production testing, and modular PXI Express test applications.
