:MEASure:ARRay:AFANalyser:GROup
:MEASure:ARRay:AFANalyser:ALL
Syntax
:MEASure:ARRay:AFANalyser:GROup <int1>
Parameters
int1 is an integer.
The minimum value for int1 is 0, the maximum value is 100. The default value for
int1 is 0.
Description
Performs the audio tests, specified with the :CONF:MEAS:GRO:AFAN command
for a specific number of times (set with the int1 parameter). To read out the entire
measurement results array, use the :FETCh:AFAN:GROup command.
Notes:
– Please keep in mind that the start of a new AF test will always terminate all
other measurements (see section “The MEASure subsystem” on page 237 for
details).
– To perform any audio measurements on your Willtek 4400, the Audio Option
must be installed.
– For further details regarding group measurements, please refer to section
“:MEASure:...:GROup” on page 244.
– More information regarding ARRay measurements can be found in section
“MEASure:ARRay” on page 240.
Query
The query form of this command will start the sequence of audio measurements as
specified with the :CONF:MEAS:GRO:AFAN command for a specific number of
times (set with the int1 parameter). As soon as all measurements have been com-
pleted, a string will be delivered back. It will contain floating point real numbers,
representing the measurement result values. The order of the measurement result
values returned is as described below (see command
:MEAS[:GSM]:ARR:AFAN:ALL).
The single measurement result values are separated by commas.
Note: The number of measurement result values delivered back is the number of
measurement result values of a single test run multiplied with the int1 parameter.
Example
:CONF:MEAS:GRO:AFAN SIN,FREQ
:MEASure:ARRay:AFAN:GROup? 3
In this example, the group of measurements is defined by a SINAD measurement,
combined with an AF frequency measurement. This group of measurements will be
carried out three times. After all measurements have been completed, a result string
will be delivered back, containing six measurement result values.
The measurement result values returned are:
"1000.0,50.5,1000.1,50.1,999.9,50.6".
Because of the internal order, the first (third and fifth) measurement result value
delivered back is the audio frequency, the second (fourth and sixth) one the SINAD.
Syntax
:MEASure:ARRay:AFANalyser:ALL <int1>
Parameters
int1 is an integer.
The minimum value for int1 is 0, the maximum value is 100. The default value for
int1 is 0.
