GPIB Programming
Analyzer Command Syntax
Some codes require appendages (
ON
,
OFF
,
1
,
2
, etc.). Codes that do not have a front-panel
equivalent are GPIB only commands. They use a similar convention based on the common
name of the function.
Valid Characters
The analyzer accepts the following ASCII characters:
• letters
• numbers
• decimal points
• +/
−
• semicolons (;)
• quotation marks (“)
• carriage returns (CR)
• linefeeds (LF)
Both upper- and lower-case letters are acceptable. Carriage returns, leading zeros, spaces,
and unnecessary terminators are ignored, except for those within a command or
appendage. If the analyzer does not recognize a character as appropriate, it generates a
syntax error message and recovers at the next terminator.
