National Instruments PXI-2545

The National Instruments PXI-2545 RF Multiplexer Switch Module (Part Number: 778572-45) is designed to optimize the management of RF signals in automated testing environments. This module features internal termination that mitigates high-power reflections from open channels, making it particularly suitable for applications where maintaining signal integrity is crucial. It delivers exceptional performance with low insertion loss, a consistent Voltage Standing Wave Ratio (VSWR), and high isolation, which minimizes signal degradation. The PXI-2545 efficiently connects multiple inputs to a single output or vice versa, simplifying wiring configurations in automated test systems. With four channels and a switch bandwidth of up to 2.7 GHz, this module supports a wide range of RF applications and is ideal for interfacing measurement or signal generation instruments with multiple devices under test (DUTs). The PXI-2545 utilizes various relay types, including armored electromechanical relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, allowing users to select the most suitable option based on their specific requirements. For seamless operation, programming can be achieved through the NI-SWITCH controller software, which is compatible with IVI and includes extensive documentation, sample programs, and a front-panel application for intuitive switch management. Additionally, NI Switch Executive provides advanced tools for complex switching system administration, enabling users to design, develop, and implement their switching frameworks with ease. The module dimensions are 8.5 x 0.8 x 5.1 inches and it weighs 9 ounces. The PXI-2545 is backed by a 2-3 year warranty, and user and maintenance manuals are readily available for download.
