Note 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 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 hrst word, and the fourth mnemonic letter is the &St 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 4 letters are the category label derived using rule 1. The last 4 letters are the function specifier, 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 PENNDATA, PENNMEMO.

The code naming guidelines, listed in Table 1 l-2, are used in order to:

nmake commands more meaningful and easier to remember

nmaintain compatibility with other products (including the HP 8510)

Note There are times when these guidelines are not followed due to technical considerations
