There is also an address for the system controller . This address refers to the
controller when the network analyzer is being used in pass-control mode . This
is the address that control is passed back to when the analyzer-controlled
operation is complete .
Analyzer Command Syntax
Code Naming Convention
The analyzer HP-IB commands are derived from their front-panel key titles (where possible),
according to this naming convention:
Simple commands are the rst four letters of the function they control, as in POWE, the
command name for power . If the function label contains two words , the rst three mnemonic
letters are the rst three letters of the rst word, and the fourth mnemonic letter is the rst
letter of the second word. F or 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 rst 4 letters are the category label
derived using rule 1. The last 4 letters are the function specier , again derived using rule 1. As
an example , category pen numbers are represented by the command PENN, which is used in
combination with several functions such as PENND A T A, PENNMEMO .
The code naming guidelines , listed in T able 11-1, are used in order to:
make commands more meaningful and easier to remember
maintain compatibility with other products (including the HP 8510)
Note
There are times when these guidelines are not followed due to technical
considerations .
