Rules for Using a Channel List
Many of the SCPI commands for the 34980A include a channel list
parameter which allows you to specify one or more channels.
From the remote interface, the channel number has the form (@sccc),
where s is the mainframe slot number (1 through 8) and ccc is the
channel number. You can specify a single channel, multiple channels,
or a range of channels.
The following command closes channel 10 on the module in slot 3.
ROUT:CLOS (@3010)
The following command closes channels 10, 12, and 15 on the module
in slot 2.
ROUT:CLOS (@2010,2012,2015)
The following command closes channels 5 through 10 (slot 1) and channel
15 (slot 2). When you specify a range of channels, any channels that are
invalid will be ignored (no error will be generated) but the first and last
channel in the range must be valid.
ROUT:CLOS (@1005:1010,2015)
The Analog Bus relays (numbered s911, s912, s913, etc.) on the
multiplexer and matrix modules are ignored if they are included in a
range of channels. An error will be generated if an Analog Bus relay is
specified as the first or last channel in a range of channels. For example,
the following command closes all valid channels between channel 30
(slot 1) and channel 5 (slot 2). In addition, this command closes Analog
Bus relay 911 on the module in slot 1 (Bank 1). Note that although the
specified range of channels includes the other Analog Bus relays, they are
ignored and are not closed by this command.
ROUT:CLOS (@1030:2005,1911)
The following command will generate an error since the Analog Bus relays
cannot be specified as the first or last channel in a range of channels
(none of the channels will be closed).
ROUT:CLOS (@1005:1911) !Generates an error
In the following command, since the optional <ch_list> parameter is
omitted, the command will be applied to the internal DMM. If the internal
DMM is disabled or is not present, an error will be generated.
INP:IMP:AUTO ON !Applies to the internal DMM
