HP / Agilent 34906A 2 GHz Dual 1:4 RF Mux, 75 Ohm Module for 34970A/34972A

The HP/Agilent 34906A is a 2 GHz dual 1:4 RF multiplexer module that expands the switching capabilities of Agilent/Keysight 34970A and 34972A Data Acquisition/Switch Units. Purpose-built for 75 Ohm systems, this plug-in module routes radio frequency and high-frequency signals with independent control over two separate 1:4 signal paths. Engineers deploy it for automated RF signal routing, antenna selection, component testing, and system-level signal management in production and development environments.
