8.3.4 Headers
The names of commands for the 3332 are as far as possible mnemonic.
Furthermore, all commands have a long form, and an abbreviated short form.
In command references in this manual, the short form is written in upper
case letters, and then this is continued in lower case letters so as to
constitute the long form. Either of these forms will be accepted during
operation, but intermediate forms will not be accepted. Further, during
operation both lower case letters and upper case letters will be accepted
without distinction.
Response messages generated by the 3332 are in long form and in upper
case letters.
Whether or not headers are prefixed to response messages is set by the
"HEADer" command. It is essential to prefix headers to program messages.
(1) Command program headers
There are three types of command: simple commands, compound commands,
and standard commands.
① Simple command header
This header is a sequence of letters and digits.
HEADer
② Compound command header
This header is made up from a plurality of simple command type headers
marked off by colons.
VOLTage:RANGe
③ Standard command header
This header begins with an asterisk, and continues with a standard command
stipulated by IEEE 488.2.
*RST
(2) Query program headers
These are for commands used for interrogating the unit about the results of
operations, about measured values, or about the current states of settings for
the unit. As shown by the following examples, they can be recognized as
queries by a question mark appearing after the program header. The structure
of the header is identical to that of a command program header, with "?"
always being affixed to the last command. There are queries possible in
each of the three previously described types of command form.
