The Agilent/Keysight E1470A is a VXIbus C-size RF multiplexer module delivering high-density signal routing for automated test systems. It integrates twenty 3:1 multiplexer configurations that cascade to form larger architectures—from a single 60:1 multiplexer to multiple parallel configurations such as 6:1 or 9:1. Up to two expander modules can be controlled by a single RF multiplexer, extending functionality to eighteen 4:1 multiplexer banks. All channels open upon power-up, ensuring safe initialization.
