Example 2 - Specifying the Source List Parameter
The MEASure command has three optional parameters, an expected power value,
a resolution and a source list. These parameters must be entered in the specified
order. If parameters are omitted, they default from the right. The parameter
DEFault is used as a place holder.
The following example uses 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.
The operation of the MEAS1? command when the source list parameter is
defaulted is described in the note
For the N1911A it is not necessary to specify a channel as only one channel is

available.
Example 3 - Specifying the Expected Power Parameter
The previous example details the three optional parameters which can be used
with the MEASure? command. 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 If the current setting of the power sensor's range is no longer valid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.
