HP E1472A Six 1x4 50 Ohm RF Multiplexer

The HP E1472A 50 Ohm RF Multiplexer is a C - size, 1-slot, register- based VXI module. It is the ideal choice to route test signals from your application to your test instruments (i.e., oscilloscope and spectrum, network, distortion analyzers, or other RF equipment). The HP E1472A is functionally identical to the HP E1474A 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 HP E1472A via the HP E1473A 50 Ohm RF multiplexer expander or via the HP E1475A 75 Ohm RF multiplexer expander.

The HP E1472A 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 1x4 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 nonlatching armature relay.
