Used National Instruments PXI-2594 PXI RF Multiplexer Switch Module

2.5 GHz, 50 Ω, 4x1 PXI RF Multiplexer Switch Module—The PXI‑2594 is ideal for applications that require the routing of high-frequency signals inside automated test equipment (ATE) systems because it can switch signals with very low insertion loss.

The module also features excellent insertion loss, voltage standing wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use the onboard relay count tracking feature to predict relay lifetime and reduce unexpected system downtime
