The National Instruments PXI-2554 (Part Number: 778572-54) is a high-performance PXI RF Multiplexer Switch Module designed for efficient switching of signals ranging from DC to 2.5 GHz. Featuring a characteristic impedance of 75 Ohms, this 4x1 multiplexer is ideal for high-frequency video signal routing in automated test equipment (ATE) systems. The module is rated for a maximum voltage of 30 Vrms and supports a switching current of up to 500 mA, ensuring reliable performance in demanding applications. The PXI-2554 boasts low insertion loss, with a maximum of less than 1.7 dB at 2.5 GHz and a typical loss under 1.2 dB. Additionally, it delivers excellent voltage standing-wave ratio (VSWR) values of less than 1.75, with typical values under 1.5, making it a preferred choice for high-frequency environments. The inclusion of electromechanical relays and a minimum pulse width of 150 ns enhances its versatility. The module also offers a relay count tracking feature to minimize unexpected system downtime. Compatible with the NI-SWITCH IVI-compliant driver for streamlined operation, the PXI-2554 can be further optimized using the NI Switch Executive software, which provides an intuitive management platform for larger channel-count switching systems. The unit has overall dimensions of 8.5 x 0.8 x 5.1 inches and weighs 7.2 ounces, backed by a 2-3 year warranty.
