2.5 GHz, 75 Ω, Dual-Terminated SPDT PXI RF Relay Module—The PXI‑2559 is a general-purpose switch module featuring two independently terminated single‑pole double‑throw (SPDT) relays. 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 PXI‑2559 termination resistors minimize reflections on open channels and protect your source or device under test from damage. 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.
