SCPI Language Conventions

Throughout this guide, the following conventions are used for SCPI command syntax for remote interface programming:

•Braces ( { } ) enclose the parameter choices for a given command string. The braces are not sent with the command string.

•A vertical bar ( ) separates multiple parameter choices for a given command string.

•Triangle brackets ( < > ) indicate that you must specify a value for the enclosed parameter. The brackets are not sent with the command string.

•Some parameters are enclosed in square brackets ( [ ] ). This indicates that the parameter is optional and can be omitted. The brackets are not sent with the command string. If you do not specify a value for an optional parameter, the instrument chooses a default value.

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.
