Switching Channels

Switching
32 Using the RF Multiplexer
For general purpose switch operation, you can connect a signal by closing a specific
channel to its COMmon. One channel per bank will be connected to COMmon at
all times, and only one channel per bank can be closed at a time. The following
channel configurations are possible.
• Close channels 00 to 03 by connecting a channel to COM00.
• Close channels 10 to 13 by connecting a channel to COM10.
• Close channels 20 to 23 by connecting a channel to COM20.
• Close channels 30 to 33 by connecting a channel to COM30.
• Close channels 40 to 43 by connecting a channel to COM40.
• Close channels 50 to 53 by connecting a channel to COM50.
Use CLOSe channel_list to close a channel to COMmon. channel_list has the form
(@ccmmnn) for a single channel, and (@ccmmnn,ccmmnn,...) for two or more
channels.
• cc = card number (01-99).
• mm = module number (00-02).
• nn = channel number (00-03, 10-13, 20-23, 30-33, 40-43, 50-53).
Switching configurations include standard, matrix, and tree.
The following examples are shown using multiple configurations (multiple-module
switchbox and single module switchbox with Expander modules) to illustrate
programming differences. It is important that the user understand that all the
examples shown could have been performed using only one HP E1472A or E1474A
RF Multiplexer module.
Use standard switching to switch channels n0-n3 to COM n0 (where n = Switching
bank number 0 to 5). One channel per bank can be connected to its common at a
time.
This example connects channel 11 to COM10 of the RF Multiplexer in a standard
configuration. The RF Multiplexer, without Expander modules, is defined as a
single-multiplexer switchbox instrument. As shown in Figure 3-1,
to connect COM 10 to channel 11, execute: CLOS (@111).
