The Keysight 34941A RF multiplexer module for the 34980A Multifunction Switch/Measure Unit offers bi-directional switching for test signals from DC to 3 GHz. 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 large multiplexer - up to 97 cascaded RF channels in a single 34980A mainframe.
