The Agilent E1474A 75 ohm RF Multiplexer is a C-size, 1-slot, register-based VXI module. It is the ideal choice for video and telecommunications applications. The E1474A is functionally identical to the E1472A except for output impedance.
The RF multiplexer can be used as six multiplexers or combined with others to form a larger tree-switched multiplexer or a limited stubless matrix. You can easily and inexpensively expand the E1474A via the E1475A 75 ohm RF multiplexer expander or via the E1473A 50 ohm RF multiplexer expander.
The E1474A can easily be programmed with SCPI commands to scan multiple channels, where each channel is switched to its common, one at a time. This module is arranged as six independent banks of channels (Bank 0 through Bank 5), 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. The multiplexer relays are arranged in a tree-switched configuration, providing high isolation and low VSWR. Each channel consists of a non-latching armature relay.
