The National Instruments PXI-2599 (Part Number: 778572-99) is a versatile Dual SPDT RF Relay Module designed for PXI platforms, capable of handling frequencies up to 26.5 GHz and characterized by a 50 Ω impedance. This general-purpose module is ideal for routing microwave and RF signals in automated testing environments. It features an integrated relay count tracking capability that predicts relay lifetimes, thereby minimizing unplanned downtimes. With a maximum carry current of 1.73 Arms per channel and a maximum RF carry power of 150 W at a 50 Ω load, the PXI-2599 operates effectively even under demanding conditions, achieving less than 0.7 dB insertion loss and exceeding 55 dB open channel isolation. The device supports switch load specifications with a minimum of -35 dBm, and can manage surge voltages up to 500 V while being rated for signal voltages up to 100 V. This module is engineered for a recommended cycle speed of 5 channels per second, utilizing latching electromechanical relays made from gold-plated beryllium copper that boast an exceptional mechanical life expectancy of 10 million cycles. With physical dimensions of 21.6 cm x 2.0 cm x 13.0 cm and a weight of approximately 260 g (9.2 oz.), the PXI-2599 occupies a single slot in a 3U PXI chassis. Additionally, it can interface with triggering signals via PXI trigger lines <0...7>. For further details, a user manual and maintenance documentation are available for download. Pricing inquiries should be directed to a National Instruments sales representative.
