The Agilent E1366A 50 Ohm RF Multiplexer is a B-size, 1-slot, register- based VXI module. It is the ideal choice to switch test signals to your oscilloscope and spectrum, network, distortion analyzers, or other RF equipment. The E1366A is identical to the E1367A, except that the E1367A has a 75 Ohm characteristic impedance.

Switching consists of connecting a channel to its common terminal. The E1366A can easily be used with SCPI commands to scan multiple channels, where each channel is switched to its common, one at a time. When open (disconnected from common), each channel is connected to a 50 Ohm temination.

This multiplexer module is arranged as two independent banks of channels (Bank 0 and Bank 1), each acting as a 1 x 4 one-wire multiplexer. Only one channel in each bank can be connected to its common at any time. Each channel consists of a non-latching armature relay. At power-on or reset, all channels are open and connected to their termination resistors. The termination resistor can be removed if desired. The multiplexer relays are arranged in a tree-switched configuration, providing high isolation and low VSWR.
