:MEAS:ARR:AFAN:DCVoltage
:MEASure:ARRay:AFAN:FREQuency
Query
The query form of this command will perform the measurement the specified number
of times (int1 parameter). As soon as all measurements have been completed, all
measurement result values will be returned in a string. The string delivered back will
contain int1 floating point real numbers. The physical dimension of the measure-
ment result values is volt, measured peak-to-peak (V
pp
).
The single measurement results are separated by commas.
Example
:MEAS:ARR:AFANanlyser:ACVoltage:PEAKp? 5
The string returned is: "0.7,0.8,0.75,0.71,0.79".
Syntax
:MEAS:ARR:AFAN:DCVoltage <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 measurement of the RMS-valued AC component of a DC signal applied
to the audio analyser a specific number of times (set with the int1 parameter). To
read out the entire measurement results array, use the :FETCh:AFAN:DCV com-
mand.
Note: Any AF test command will need the Audio Option to be installed on your
Willtek 4400.
Query
The query form of this command will perform the measurement the specified number
of times (int1 parameter). As soon as all measurements have been completed, all
measurement result values will be returned in a string. The string delivered back will
contain int1 floating point real numbers. The physical dimension of the measure-
ment result values is volt, RMS-valued (V
rms
).
The single measurement results are separated by commas.
Example
:MEAS:ARR:AFANanlyser:DCVoltage? 5
The string returned is: "0.025,0.029,0.019,0.030,0.025".
Syntax
:MEASure:ARRay:AFAN:FREQuency <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 measurement of the frequency of the audio signal applied to the audio
analyzer a specific number of times (set with the int1 parameter). To read out the
entire measurement results array, use the :FETCh:AFAN:FREQ command.
Note: Any AF test command will need the Audio Option to be installed on your
Willtek 4400.
Query
The query form of this command will perform the measurement the specified number
of times (int1 parameter). As soon as all measurements have been completed, all
measurement result values will be returned in a string. The string delivered back will
contain int1 floating point real numbers. The physical dimension of the measure-
ment result values is Hertz.
The single measurement results are separated by commas.
Example
:MEASure:ARRay:AFANanlyser:FREQ? 5
The string returned is: "1000.0,1000.5,1000.9,999.9,1000.0".
