2.5 GHz, 75 Ω, Quad SPDT PXI RF Relay Module—The PXI‑2558 is a general-purpose single‑pole double‑throw (SPDT) switch module. You can use it to add flexibility to your video switch network or to maintain uniform signal paths across multiple channels when building high‑channel‑count multiplexers. The module also features excellent insertion loss, voltage standing wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use its onboard relay count tracking feature to predict relay lifetime and reduce unexpected system downtime.
