Multiplexer Module Description

The HP E1366A 50Ω RF Multiplexer (2 x 4:1) and the HP E1367A 75Ω RF Multiplexer (2 x 4:1) are VXIbus and VMEbus B-size register-based products which provide bidirectional switching and scanning for user inputs and outputs. The multiplexers can operate in a B-size VXIbus or VMEbus mainframe or (with an adapter) in a C-size VXIbus mainframe.

For the RF multiplexers, switching consists of connecting a channel to its common terminal. Scanning consists of connecting a series of channels (one at a time) to the appropriate common terminal.

Basic Operation The multiplexers consist of two banks of channels (bank 0 and bank 1) to form two 4:1 multiplexers. Bank 0 includes channels 00 through 03 and com 00. Bank 1 includes channels 10 through 13 and com 10. S`ee Figure 1-1 for a simplified switching diagram.

Each channel is switched (connected to its common) by closing the appropriate (nonlatching) relays. Channels 00 through 03 can be switched to com 00, and channels 10 through 13 can be switched to com 10. Only one channel in each bank can be connected to its common at a time.

User inputs and outputs to each channel are made through BNC connectors. When open (disconnected from common), each channel is terminated in its characteristic impedance (50Ω for the E1366A, 75Ω for the E1367A).

A termination resistor (50Ω for the HP E1366A or 75Ω for the HP E1367A) is mounted on each channel, but can be removed as desired. At power-on or reset, all channels are open and terminated in their characteristic impedance, and both commons are open.
