HP E1368A manual Example 4 x 1 Multiplexer, To route signal B to the output, execute

Page 38

Example: 4 x 1 Multiplexer

This example shows how to configure the HP E1368A Microwave Switch to select one of four signals for output. For the example, all three switches (channels 00 through 02) will be used. Figure 3-6 shows how to connect channels 00 through 02.

To route signal "A" to the output, execute:

OPEN (@100,102)	Connects signal "A" (channel 00
	port 1) to the output (channel 02
	port C).

To route signal "B" to the output, execute:

CLOS (@100);OPEN (@102)	Connects signal "B" (channel 00
	port 2) to the output (channel 02
	port C). To route signal "C" to the
	output, execute:
OPEN (@101);CLOS (@102)	Connects signal "C" (channel 01
	port 1) to the output (channel 02
	port C).
To route signal "D" to the output, execute:
CLOS (@101,102)	Connects signal "D" (channel 01
	port 2) to the output (channel 02
	port C).

Comments Unused signals are terminated into 50Ω (internal to the switch).
