Analyzer Command Syntax
Code Naming Convention
The analyzer GPIB commands are derived from their front-panel key titles (where
possible), according to this naming convention:
Simple commands are the first four letters of the function they control, as in POWE, the
command name for power. If the function label contains two words, the first three
mnemonic letters are the first three letters of the first word, and the fourth mnemonic
letter is the first letter of the second word. For example, ELED is derived from electrical
delay.
If there are many commands grouped together in a category, as in markers or plotting pen
numbers, the command is increased to 8 letters. The first four letters are the category label
and the last four letters are the function specifier. As an example, category pen numbers
are represented by the command PENN, which is used in combination with several
functions such as PENNDATA, PENNMEMO.
The code naming guidelines, listed in Table 3-1, are used in order to:
• make commands more meaningful and easier to remember
• maintain compatibility with other products (including the 8510 series analyzers)
NOTE There are times when these guidelines are not followed due to technical
considerations.
