National Instruments PXI-2556

The National Instruments PXI-2556 Multiplexer Switch Module (Part Number: 778572-56) is designed for high-channel count applications requiring the interconnection of measurement or signal generation instruments to multiple test points within devices or units under test (DUT or UUT). This PXI RF multiplexer module features two banks and four channels, with a notable switch bandwidth of 2.5 GHz and a characteristic impedance of 75 Ohm. The PXI-2556 utilizes electromechanical relays to ensure reliable switching performance. Users can program the switches through the NI-SWITCH driver software, which is compatible with IVI and includes comprehensive documentation, sample programs, and an intuitive soft front panel application for seamless switch control. For advanced management of complex switching environments, NI Switch Executive provides additional software tools to aid in the design, implementation, and deployment of switching systems. When initiating a scan with the PXI-2556, it is essential for the measurement device to be armed and waiting for a trigger before enabling scanning on the switch module. This ensures the proper signal routing and synchronization necessary for accurate measurements. The module measures 8.5 x 0.8 x 5.1 inches and weighs 8.0 ounces. A user manual and maintenance manual are available for download, and the product is offered with a warranty of 2 to 3 years. For pricing, please contact a sales representative for a quote.
