The National Instruments PXI-2544 (Part Number: 778572-44) is a high-performance PXI RF multiplexer switch module designed for production test applications. This 8x1 terminated multiplexer efficiently directs RF signals up to 6.6 GHz, featuring advanced solid-state relay technology that ensures infinite relay life and fast switching times. Front-mounted SMA connectors facilitate easy connections to RF devices, while individual terminations on each common (COM) line and channel minimize signal reflections and protect the test instruments.

Although the bandwidth specification of the PXI-2544 is subject to vendor standards, users can route higher frequency signals; however, greater degradation may occur compared to lower frequency signals. To select the optimal module for a given application, it is essential to consider parameters such as insertion loss, voltage standing wave ratio (VSWR), and isolation performance. The PXI-2544 leverages the PXI platform's intrinsic timing and synchronization capabilities, enabling seamless communication with other PXI instruments within the chassis. Users can store switch configurations onboard, utilizing the integrated hardware for advanced scanning and triggering operations, which significantly reduces software overhead and bus latency. This feature enhances test execution speed and ensures more consistent timing across measurements.

The module's dimensions are 8.5 x 0.8 x 5.1 inches, with a weight of 19 ounces. The PXI-2544 is backed by a warranty of 2 to 3 years, and user and maintenance manuals are available for download. For pricing inquiries, please contact a sales representative.
