Programming Guide
If an <expected_value> parameter is outside the measurement
capabilities of the Counter model, an error is generated, and the
command does not execute.
See "Descriptions of the Measurement Functions" on page 4-16 for a
description of each of the measurement functions.
See Table 4-2 for a summary of the <function>, <parameters>, and
<source_list> for each of the measurement functions.
When [:SCALar]:<function> is specified, the instrument retrieves the
specified result if it matches the current measurement type or can be
derived from the current measurement type.
When [:SCALar]:<function> is omitted, the function specified/used by
the last :CONFigure, :MEASure, :READ, or FETCh is used, if
possible.
Issuing this query while a measurement is in progress prevents
further commands from being processed until the measurement
completes. This hold-off action can only be canceled 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.
