Opening Multiplexer Channels
This example opens channel 00 of a multiplexer module card number 1 and
channel 15 of multiplexer module card number 2 in a single switchbox.

Parameter Name
channel_list

Channel List: Valid channel lists are:
a single channel, use
–
for multiple channels, use
–
sequential channels, use
–
a group of sequential channels, use
–
or any combination.

•
Defining the Channel List. When executing
channel list is checked for valid card and channel numbers. An error
is generated for an invalid channel list.
•
Downloading a Scanning List: The channel_list is automatically
downloaded into RAM on the FET multiplexer modules for
TRIG:SOUR DBUS
complete list is downloaded onto each module in an instrument. The
channels are advanced with no direct intervention by the mainframe
CPU during the scan. If an instrument contains mixed modules
(FET and Relay Multiplexers), the scan list will not be downloaded.
