## Key Features At A Glance

-   Six independent 1x4 multiplexers in a 1-slot, C-size, register-based VXI module
-   Switches signals up to 1.3 GHz with characteristic impedance of 75 Ω
-   Tree-switched relay configuration for high isolation and low VSWR
-   SMB male front-panel connectors for high-performance RF connections
-   Non-latching armature relays — all channels open at power-up/down
-   Controls external E1475A 75 Ω and E1473A 50 Ω RF multiplexer expanders for system scaling
-   Maximum input rating of 42 V, 1 A, and 24 W/24 VA per channel or common

The Agilent E1474A is a Six 1x4, 75 Ω RF Multiplexer built as a C-size, 1-slot, register-based VXI module. It is positioned for video and telecommunications applications where 75-ohm signal paths are required, and it is functionally identical to the E1472A except for output impedance. The module organizes its switching into six independent banks (Bank 0 through Bank 5), each acting as a 1x4 one-wire multiplexer, with only one channel in each bank connected to its common at any time.

Typical applications for the E1474A include video signal routing and telecommunications switching, where multiple 75-ohm sources need to be routed through a single common point. The module can be used as six independent multiplexers, or combined with other E1474A units to form a larger tree-switched multiplexer or a limited stubless matrix. The E1474A can also drive external relays requiring 5 V, 12 V, or 24 V control signals, and it directly controls the E1475A 75 Ω and E1473A 50 Ω RF multiplexer expanders for system expansion.

ValueTronics stocks, inspects, and ships test and measurement equipment from a 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every pre-owned E1474A passes through our in-house bench before it leaves the building — unlike pass-through brokers and drop-shippers, we physically handle the modules we sell. That hands-on workflow is how we verify connector condition on the SMB ports, confirm the module powers up correctly, and document what is actually in the box.

## Brand Heritage

The E1474A was originally developed under the Hewlett-Packard test and measurement banner. HP spun off its test and measurement business as Agilent Technologies in 1999, and Agilent's electronic measurement division became Keysight Technologies in 2014. Modules carrying the Agilent badge — like the E1474A — are part of that same engineering lineage.

**Important:** Maximum voltage: 42 V (center or shield-to-center, shield or chassis). Maximum current: 1 A DC or AC RMS per channel or common. Maximum power: 24 W DC or 24 VA AC per channel or common.**Important:** Cables and connectors are not included with the multiplexer. Various 75 Ohm cables are available from Agilent for connecting to the SMB connectors on the front panel; adapters and other connectors are also available, including from Johnson Components.**Important:** Expansion modules (E1475A 75 Ohm RF multiplexer expander or E1473A 50 Ohm RF multiplexer expander) are required for larger tree-switched multiplexer or limited stubless matrix configurations and are sold separately.**Important:** The E1474A is functionally identical to the E1472A except for output impedance (75 Ohm vs 50 Ohm).Recommended pairing: use the E1475A 75 Ω RF multiplexer expander, or the E1473A 50 Ω RF multiplexer expander, to scale switching capacity under E1474A control as described in the datasheet.
