Command
Separator
A colon (:) always separates one command keyword from a lower level command
keyword as shown below:
ARM:LAY2:SOUR EXT
Abbreviated
Commands
The command syntax shows most commands as a mixture of upper and lower case
letters. The upper case letters indicate the abbreviated spelling for the command.
For shorter program lines, send the abbreviated form. For better program
readability, you may send the entire command. The AFG will accept either the
abbreviated form or the entire command.
For example, if a command’s syntax contains the keyword
COUNt, then COUN and
COUNT are acceptable forms. Other forms of COUNt such as COU will generate an
error.
You can use upper or lower case letters. Therefore,
COUNT, coun, or Coun are all
acceptable.
Implied
(Optional)
Commands
Implied or optional commands are those which appear in square brackets ([ ]) in the
command syntax. The brackets are not part of the command, and are not sent to the
AFG. Suppose you send the following command:
ARM:COUN 100
In this case, the AFG responds as if you had executed the command as:
ARM:STARt:LAYer1:COUNt 100
Variable
Command
Syntax
Some commands will have what appears to be a variable syntax. For example:
[SOURce:]MARKer:ECLTrg<n>[:STATe] <mode>
In this command, <n> is replaced by a number. No space is left between the
keyword (
ECLTrg) and the number because the number is part of the keyword.
