Agilent/Keysight E1367A

The Keysight E1367A is a B-size, 1-slot VXI module that delivers dual-bank RF signal routing for video and telecommunications systems. This register-based multiplexer functions as two independent 1×4 one-wire switches, enabling selection of four input channels per bank to a common output terminal. Operating up to 1.3 GHz with 75 Ohm characteristic impedance, the E1367A employs non-latching armature relays in a tree-switched configuration to achieve high isolation and low VSWR performance. Unselected channels default to internal 75 Ohm termination resistors—removable if required—maintaining signal integrity across all eight channels. Programmed via SCPI commands over the VXIbus interface, the module initializes with all channels open upon power-on or reset, making it ideal for automated RF test and measurement applications requiring reliable, low-loss signal routing.
