Response
When the controller sends a query with a question
mark, the DLM4000 returns a response message to
the query. The DLM4000 returns response messages
in one of the following two forms.
• Response Consisting of a Header and Data
Responses that can be used as program messages
without any changes are returned with command
headers attached.
Example
:ACQUire:MODE?<PMT>
-> :ACQUire:MODE NORMAL<RMT>
• Response Only Consisting of Data
Responses that cannot be used as program
messages unless changes are made (query-only
commands) are returned without headers. However,
there are query-only commands whose responses
the DLM4000 will attach headers to.
Example
:MEASure:TRACe1:AREA1:PTOPeak:
VALue?<PMT> -> 10.0E+00<RMT>
If You Want the DLM4000 to Return Responses
without Headers
You can configure the DLM4000 so that even responses
that have both headers and data are returned without
headers. Use the
COMMunicate:HEADer
command
for this purpose.
Abbreviated Form
The DLM4000 normally returns response headers with
the lower-case section removed. You can configure the
DLM4000 so that full headers are returned. Use the
COMMunicate:VERBose
command for this purpose.
The sections enclosed in braces ([ ]) are also omitted
in the abbreviated form.
