The Keysight 34942A RF multiplexer module for the 34980A Multifunction Switch/Measure Unit offers bi-directional switching broadband signals. High channel isolation ensures quality dynamic range measurements with your oscilloscope, spectrum analyzer, or other instrumentation.

The RF multiplexers are configured as four independent 1x4 RF multiplexers on a single module. Individual multiplexers are isolated from each other and the Mainframe chassis to prevent ground loops. Multiple banks can be cascaded together to create an even larger multiplexer - up to 97 cascaded RF channels in a single 34980A Mainframe.
