2.3 Response
On receiving a query from the controller, this
instrument returns a response message to the
controller. A response message is sent in one of the
following two forms.
• Response consisting of a header and data
If the query can be used as a program message
without any change, a command header is attached
to the query, which is then returned.
Example
SAMPLE:GATE:MODE?<PMT>
SAMPLE:GATE:MODE EVENT<RMT>
• Response consisting of data only
If the query cannot be used as a program message
unless changes are made to it (i.e. it is a query-only
command), no header is attached and only the data
is returned. Some query-only commands can be
returned after a header is attached to them.
Example
STATUS:ERROR?<PMT>
0,"NO ERROR"<RMT>
When returning a response without a header
It is possible to remove the header from a response
consisting of a header and data. The
"COMMunicate:HEADer"
command is used to do this.
Abbreviated form
Normally, the lower-case part 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 part enclosed by [ ] is also
omitted in the abbreviated form.

2.4 Data
Data
A data section comes after the header. A space must
be included between the header and the data. The
data contains conditions and values. Data is classified
as below.
