Command Coupling

Chapter 1
A semicolon (;) is used to separate two commands within the same
subsystem, and can also save typing. For example, sending this command
message:
ARM:LAY2:SOUR EXT;SLOP POS;COUN 10
Is the same as sending these three commands:
ARM:LAY2:SOUR EXT
ARM:LAY2:SLOP POS
ARM:LAY2:COUN 10
The typical format of commands listed in the command reference and
throughout this manual is:
[SOURce:]FREQuency:MODE <
Command headers enclosed in brackets are optional. UPPER CASE letters
in the header are required, lower case letters can be omitted. To aid in
learning the AFG command set, all headers are included in the example
programs; however, the headers are abbreviated. In an example
program, the previous statement with a mode parameter of
appear as:
SOUR:FREQ:MODE FIX
Many of the AFG SCPI commands are value coupled. This means that the
value set by one command may affect the valid limits for the values of other
commands. This can result in "Settings Conflict" errors when the program
executes. To prevent these errors, the AFG commands must be executed in
a "Coupling Group".
The AFG uses one coupling group. Commands not in the coupling group
must precede or follow commands in the coupling group. Executing
uncoupled commands in the coupling group breaks the coupling and can
cause a "Settings Conflict" error.
The coupling group and associated commands can be found in Appendix B,
Table B-2.
