Description
The Keysight 44478B Multiplexer Module is an ideal choice for broadband switching of high-frequency or fast pulse signals. Dual 1-to-4 multiplexers provide bi-directional switching of signals from DC to 1.3GHz. High-channel isolation (>55 dB at 1 GHz) assures quality dynamic-range measurements using spectrum, network, or distortion analyzers. Each 1-to-4 multiplexer consists of seven relays in a “tree” structure, which provides high isolation and low VSWR (voltage standing wave ratio). All the connectors on the module’s edge are female BNC for ease of wiring. Off-channels can be terminated in resistors to maintain proper operation of DUT circuitry. Simply plug a 50/75 Ohm SMB type resistive termination onto the on-board male SMB connector provided for each channel.
