Power Meter Remote Operation

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.

MEAS1? DEF,DEF,(@1)
The operation of the MEAS1? command when the source list parameter is
defaulted is described in the note
"Keysight N8262A"
on page 65.
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. 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sensor's range is no longer valid for the new measurement, specifying the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 sensor's lower range (refer to
"Range"
on
page 86 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 displayed on the lower window.
