Using INITiate and FETCh?
Example 3 - Specifying the expected power parameter
The previous example details the three optional parameters which can be used
with the CONFigure command and READ? query. The first optional parameter is
used to enter an expected power value.
The following example uses the expected value parameter to specify an expected
power of –20 dBm. The resolution parameter is set to its default value, leaving it
at its current setting.
Using READ?
Some finetuning of the measurements can be performed using the CONFigure
command and READ? query. For example, in the earlier program segment, some
finetuning can be performed by setting the filter length to 1024 and the trigger
delay off.
1 ABOR
2 CONF -20,DEF,(@1)
3 SENS:AVER:COUN 1024
4 TRIG:DEL:AUTO OFF
5 READ?
ABOR Aborts the measurement.
CONF DEF,DEF,(@1) Configures the measurement to measure using the
current expected power and resolution settings.
INIT Sets it to wait for a trigger state.
FETC? DEF,DEF,(@1) Triggers a measurement, and then retrieves the
measurement reading.
ABOR Aborts the measurement.
CONF -20,DEF,(@1) Configures the measurement to use an expected
power of –20 dBm and the current resolution
setting.
READ? Initiates and retrieves the measurement.
