Example 3 - Specifying the expected power parameter
The previous example details the three optional parameters which can be used
with the CONFigure and READ? commands. The first optional parameter is used
to enter an expected power value. Entering this parameter is only relevant if you
are using an E-Series power sensor or N8480 Series power sensor (excluding
Option CFT). The value entered determines which of the power sensor's two
ranges is used for the measurement. If the current setting of the power sensor's
range is no longer valid for the new measurement, specifying the expected power
value decreases the time taken to obtain a result.
The following example uses the expected value parameter to specify a value of
-50 dBm. This selects the power meter's lower range (refer to
page 78 for details of the range breaks). The resolution parameter is defaulted,
leaving it at its current setting. The source list parameter specifies a channel B
measurement. The measurement is carried out on the upper window.

READ1?
Some fine tuning of measurements can be carried out using the CONFigure and
READ? commands. For example, in the above program segment some fine tuning
can be carried out by setting the filter length to 1024 and the trigger delay off.
