COMMAND :MEASure[:SCALar]:<function>? <parameters> [,<source_list>]
This query provides a complete measurement sequence: configuration,
measurement initiation, and query for result.
COMMENTS • This query is used when generic measurement is acceptable, and fine
adjustment of Counter settings is not necessary.
• 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.
• For :POWer, <resolution> must be defaulted or set to 0.01[dB].
• If an <expected_value> parameter is outside the measurement
capabilities of the Counter model, an error is generated, and the
command does not execute.
• Issuing this query while a measurement is in progress aborts the
current measurement before initiating the measurement specified in
the query. The Counter then waits for the measurement to complete.
This has the effect of holding off processing of further commands until
the desired measurement completes. This hold-off action can be
canceled only by the completion of the measurement, Device Clear,
or power-on.
• If an <expected_value> parameter is outside the measurement
capabilities of the Counter model, an error is generated, and the
command does not execute.
• For :POWer, <resolution> must be defaulted or set to 0.01[dB].
• See “Descriptions of the Measurement Functions” on Page 4-16 for a
description of each of the measurement functions.
• Refer to Table 4-2 for a summary of the <function>, <parameters>,
and <source_list> for each of the measurement functions.
