Command Tree Stucture

Many of the remote commands require a compound structure. This is done to distinguish between
different commands of the same type. The first mnemonic opens a path to a set of commands
relating to that path. The second mnemonic then defines the actual command.
This structure is illustrated in Figure 3.3. Table 4.1 on page 39 lists all of the device−dependent
commands, with the full path shown for each command and a brief explanation of its usage.

Syntax Summary

GPIB commands must contain all of the letters shown in upper case in the command definition.
Optional letters shown in lower case for some device dependent commands in Chapter 4, Command
Reference, are useful for clarity, but must be in the correct sequence.
A single white space must separate a command from its parameters or data. White space is
normally the space character (space bar). Other control characters are also interpreted as white
space. Do not use white space before the question mark in a query command.
If you encounter problems with GPIB communications, the terminator string can be the cause. Refer
also to your GPIB interface (controller) manual. The instrument accepts <NL>, or <^END>, or
<NL><^END> as a command line terminator. Many computers terminate with <CR> <NL> <^END>
(Carriage Return − New Line − EOI). The instrument ignores <CR> (Carriage Return) as white
space. The instrument terminates its responses with <CR><NL><^END>, unless you use the
TERM command to change it.
You can put more than one command on the same line (same command string) if you separate them
with a semicolon.
