National Instruments PXI-2599 PXI RF Relay Module
The National Instruments PXI-2599 (Part Number: 778572-99) is a Dual SPDT, 26.5 GHz, 50 Ohm, PXI RF Relay Module. This general-purpose RF Relay Module is designed for routing microwave or RF signals in automated test applications. The NI PXI-2599 comes with an integrated relay count tracking feature that can be utilized for the prediction of relay lifetime, as well as to reduce unexpected downtimes. This module offers 1.73 Arms maximum carry current (per channel), 150 W maximum RF carry power (at 50 Ω load), and -35 dBm minimum switch load.
The NI PXI-2599 comes equipped with latching type electromechanical relays. As far as its RF performance characteristics are concerned, this model incurs <0.7 dB insertion loss, <1.7 voltage standing wave ratio, >55 dB open channel isolation, and 25 W RF carry power while operating at ≤26.5 GHz frequency. The National Instruments PXI-2599 RF Relay Module is a Measurement Category I rated device. Thus, it is designed to carry signal voltages ≤ 100 V. However, it can withstand up to 500 V surge voltages.
The recommended cycle speed for this Relay Module is 5 channels/s. The relays utilized in this module are made of a Beryllium copper, gold-plated contact material. These relays have an expected mechanical relay life of 1 × 107 cycles. Weighing around 260 g (9.2 oz.), the NI PXI-2599 is a 3U, one slot, PXI module with physical dimensions of 21.6 cm × 2.0 cm × 13.0 cm. This module can receive and output trigger signals through PXI trigger lines <0...7>.
