The Keysight E1473A 50 ohm RF Multiplexer Expander is a C-size, 1-slot, register-based VXI module. It is the ideal choice to inexpensively increase system switching capacity to switch test signals from your application to your test instruments such as oscilloscope and spectrum, network, distortion analyzers, or other RF equipment.
The E1473A expander is connected to, and requires, either an E1472A or E1474A RF multiplexer in the same system. Up to two E1473A multiplexer expanders can be connected to one multiplexer, providing a total of eighteen 1 x 4 multiplexer banks. You can mix and match the E1473A 50 ohm and E1475A 75 ohm expanders with the E1472A 50 ohm and E1474A 75 ohm multiplexers.
