The following examples use the source list parameter to specify the measurement
channel as Channel A. The expected power and resolution parameters are
defaulted, leaving them at their current settings. The measurement is carried out
on the upper window.
Although the READ? and FETCh? queries have three optional parameters it is not
necessary to define them as shown in these examples. If they are defined they
must be identical to those defined in the CONFigure command otherwise an error
occurs.

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. 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power sensor's range is no longer valid for the new measurement, specifying the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.
