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 If the current setting of the power sensor’s range is no
longer valid for the new measurement, specifying the expected power value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 “Range” on page 60
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.
ABOR1 Aborts Channel A
CONF1 DEF,DEF,(@1) Configures the upper window to make a
Channel A measurement using the current
expected power and resolution settings
INIT1 Causes Channel A to make a measurement
FETC1? DEF,DEF,(@1) Retrieves the upper window’s measurement
