Dual 1x4 VHF Multiplexer The Agilent (now Keysight) 44472A is a VHF module and offers broadband switching capability for high-frequency and pulse signals. Two independent 50 Ohm character impedance bi-directional 1x4 switches are provided for signals from DC to 300 MHz. Very low crosstalk makes the VHF module ideal for VHF signal measurements using spectrum, network, or distortion analyzers. Furthermore it offers excellent signal integrity for multiplexing inputs of your GPIB oscilloscope or waveform analyzer. Each group of four channels is isolated from the other as well as from the chassis to prevent ground loops. BNC connectors provide ease of connection to the module.
