The module number identifies the module (RF Multiplexer, Expander #1, or
Expander #2) within the card. The number depends on the desired module (RF
Multiplexer, Expander #1, or Expander #2). Figure 1-3 illustrates the module
numbers of a typical card.
• RF Multiplexer. Module number is 00. If the RF Multiplexer
does not have Expander module(s) connected, the module
number can be omitted.
• Expander module #1 . Module number is 01. Used to select
the Expander module (if installed) connected to the RF Multiplexer
RMD 3/RMD 2 internal ribbon connector.
• Expander module #2 . Module number is 02. Used to select
the Expander module (if installed) connected to the RF Multiplexer
RMD 5/RMD 4 internal ribbon connector.
The channel numbers are 00-03,10-13,20-23,30-33, 40-43, and 50-53. The channel
is addressed using channel numbers. Use commas (,) to form a channel list. Only
valid channels can be accessed in a channel list.
The RF Multiplexer will accept and execute channel ranges (ccmmnn:ccmmnn)
without generating an error, but the result is to close the last channel in each bank
within the range specified. For example, after CLOSe (@010101:010151) is
executed, card 01, module 01 channels 03, 13, 23, 33, 43, and 51 would remain
closed.
Example RF Multiplexer Channel List
Channel Lists:
CLOSe (@10001)
CLOSe (@10101,20101)
You can send SCPI commands in either short or long form. A long form example
is:
CLOSe (@10102)
The same command shown without the lower case letters is the short form. The
command then becomes:
CLOS (@10102)
Connect channel 01 to COM 00
on the RF Multiplexer module,
card 01.
Connect channel 01 to COM 00
on the Expander #1 module,
cards 01 and 02.
