PXI Switches

PXI Switches

PXI Switches are modular switching instruments designed for National Instruments PXI and PXI Express platforms. They provide automated signal routing, multiplexing, matrix switching, and relay control capabilities for building flexible and scalable automated test systems.

PXISOURCE provides NI PXI Switching Modules for applications including automated test equipment, semiconductor testing, electronic validation, production testing, RF signal routing, and laboratory measurement systems.

What Are PXI Switches?

PXI Switches are plug-in switching modules installed inside PXI Chassis to automatically connect signals between test instruments and devices under test. They allow engineers to configure complex measurement paths without manual cable changes.

Compared with traditional standalone switching equipment, PXI Switching Modules provide higher integration, faster switching speed, better synchronization, and seamless software control through NI platforms such as LabVIEW and TestStand.

Types of NI PXI Switch Modules

PXI Multiplexer Switch Modules

PXI Multiplexer Switch Modules provide multiple input channels connected to one common output channel. They are widely used for automated scanning, sensor measurement, and multi-point testing applications.

Typical applications include voltage measurement, temperature testing, battery testing, and electronic component validation.

PXI Matrix Switch Modules

PXI Matrix Switch Modules provide flexible connection paths between multiple inputs and outputs. They are ideal for complex automated test systems requiring multiple signal routing configurations.

Matrix switching solutions are commonly used in semiconductor testing, functional testing, communication testing, and electronic verification applications.

PXI Relay Switch Modules

PXI Relay Switch Modules use mechanical or solid-state relays to control signal connections with high reliability and repeatability.

They support applications requiring precise switching, long operational life, and stable signal integrity.

PXI RF Switch Modules

PXI RF Switch Modules are designed for routing high-frequency signals in RF and wireless testing systems. They support applications such as antenna testing, communication validation, and RF device characterization.

RF switching modules help integrate multiple RF instruments into automated PXI-based test systems.

PXI High-Density Switching Modules

High-density PXI Switch Modules provide large channel counts in compact PXI form factors. They are suitable for production test systems requiring fast automated measurements across multiple devices.

These modules help reduce system complexity while improving test efficiency and throughput.
