HP E1473A VXI Six 1x4, 50 Ohm RF Multiplexer Expander

Product Summary

The HP 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, or distortion analyzers. The HP E1473A expander is connected to and requires either an HP E1472A or HP E1474A RF multiplexer in the same system. Up to two HP E1473A multiplexer expanders can be connected to one multiplexer, providing a total of eighteen 1x4 multiplexer banks. You can mix and match the HP E1473A 50 ohm and HP E1475A 75 ohm expanders with the HP E1472A 50 ohm and HP E1474A 75 ohm multiplexers.

Configuration
The HP E1473A can be installed in a VXI C-size slot, adjacent to the HP E1472A (or HP E1474A), or rack mounted externally up to eight meters from the VXI mainframe using remote extender cables. The adjacent slot can be used by another module, making the multiplexer expander a slotless device. Remote installation of the HP E1473A expander close to the device under test allows the test cable length to be kept as short as possible, reducing signal delay and insertion loss.

The switching sections of the HP E1473A 50 Ohm RF multiplexer expander and the HP E1472A 50 Ohm RF multiplexer are identical. 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. At power-on or reset, channels 00, 10,...50 areconnected to COM 00, 10,...50, respectively, and all other channels are open (unterminated).

Product Features

• Six 1x4 multiplexers
• Switch signals up to 1.3 GHz

   Opt W01	3-yr. return to HP to 1-yr. on-site warranty

HP E1473-80002	Cable extension kit


Cable Extension Kit
 
If the HP E1473A expander is physically located away from the 
mainframe, you need to order the cable extension kit. Each kit 
includes two 0.8 meter cables, each controlling three of the six 
expander banks. Up to 10 extender cables can be daisy-chained. 
To remotely install one HP E1473A expander at a distance of eight 
meters, controlling all six multiplexer banks, requires ten 
E1473-80002 kits.

Cables and Connectors

Various 50 Ohm cables are available from HP for connecting to the 
SNB connectors on the front panel of the multiplexer. Adaptors and 
other connectors are also available. Connectors are also available 
from Johnson Components:
