The
<source_list>
parameter has the same syntax as SCPI
<channel_list>
. For
example, the Frequency function uses (
@1
) to specify channel 1.
If the instrument receives an unexpected parameter, it processes the command,
ignoring the unexpected parameter, and sets the “Command Warning” bit of the
Data Questionable status reporting structure.
The response format for
:MEASure
query,
:READ?
, and
:FETCh?
is ASCII data. If no
valid data is available, the instrument generates error -230 (Data corrupt or stale).
COMMAND
:CONFigure[:SCALar]:<function> <parameters> [,<source_list>]
Configures the instrument to perform the specified function but does not initiate
the measurement.
COMMENTS
– Use
:INITiate;FETCh?
or
:READ?
to make and query a measurement.
– Parameters (other than
<source_list>
) can be defaulted by substituting the
keyword
DEFault
. The
<source_list>
parameter can be defaulted by omitting
it. The default values are specified by the particular function description.
– This command defaults several instrument settings. To change the function
only, while leaving all other instrument settings as they are, use
[:SENS]:FUNC[:ON]
.

Summary of the Measurement Instruction Commands
Command
Description
:MEASure query
This command is the simplest to use, but it allows little flexibility. This command
lets the instrument configure
itself
for an optimal measurement, initiate the
measurement, and return the result; i.e., it provides a complete measurement
sequence (:MEAS query is equivalent to the :CONF, :INIT, :FETC? command
sequence, but with no flexibility.)
:CONFigure
:READ?
The combined use of these two commands allows for more control when the
instrument performs a measurement, initiates a measurement, and returns the
result. Use this command sequence when you want to customize the configuration
between the measurement setup and acquisition.
:CONFigure
:INITiate
:FETCh?
This combination of commands provides the most flexibility the Measure
Instructions allow. This command sequence configures the instrument, initiates the
measurement as specified, and returns the result.
