Responses

When the controller sends a message unit that has a
question mark ( ? ) in its program header (query), the
instrument returns a response message to the query. A
response message is returned in one of the following
two forms.
• Response Consisting of a Header and Data
If the response can be used as a program message
without any change, it is returned with a command
header attached.
:DISPlay:MODE?<PMT> ->
Example
:DISPLAY:MODE WAVE<RMT>
• Response Consisting of Data Only
If the response cannot be used as a program
message unless changes are made to it (query-
only command), only the data section is returned.
However, there are query-only commands that
return responses with the header attached.
Example [:INPut]:POVer?<PMT> -> 0<RMT>
When You Wish to Return a Response without a
Header
Responses that return both header and data can
be set so that only the data section is returned. The
" COMMunicate:HEADer " command is used to do this.
Abbreviated Form
Normally, the lower-case section is removed from a
response header before the response is returned to
the controller. Naturally, the full form of the header can
also be used. For this, the " COMMunicate:VERBose "
command is used. The sections enclosed by braces
( [] ) are also omitted in the abbreviated form.
