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 If the current setting of the power sensor’s range is no
longer valid for the new measurement, specifying the expected power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 37 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
