2.5 GHz, 75 Ω, 8x1 PXI RF Multiplexer Switch Module—The PXI‑2557 is an RF signal multiplexer switch module. The higher channel count of the PXI‑2557 makes it ideal for test systems that require the switching of a large number of video RF signals, such as switching several video tuners under test to a single channel on the RF analyzer. 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.
