:MEAS[:CONT]:AFAN:ACVoltage:RMS
:MEAS][:CONT]:AFAN:DCVoltage
:MEAS[:CONT]:AFAN:FREQuency
Syntax
:MEAS[:CONT]:AFAN:ACVoltage:RMS
Parameters
There are no parameters.
Description
Starts a continuous measurement of the RMS-valued AC voltage of the AF signal
applied to the audio analyzer. To read out the latest measurement result, use the
:FETCh:AFAN:ACV:RMS command.
Note: Any AF test command needs the Audio Option to be installed on your Willtek
4400.
Query
The query form of this command starts the measurement and delivers a string, con-
taining a floating point real number, representing the first measurement result value.
The physical dimension is volt, RMS-valued (V
rms
).
Example
:MEAS:CONT:AFAN:ACVoltage:RMS?
String delivered back: "0.25".
Syntax
:MEAS][:CONT]:AFAN:DCVoltage
Parameters
There are no parameters.
Description
Starts a continuous measurement of the RMS-valued AC component of an applied
DC signal. To read out the latest measurement result, use the :FETCh:AFAN:DCV
command.
Note: Any AF test command needs the Audio Option to be installed on your Willtek
4400.
Query
The query form of this command starts the measurement and delivers a string, con-
taining a floating point real number, representing the first measurement result value.
The physical dimension is volt, RMS-valued (V
rms
).
Example
:MEAS:CONT:AFAN:DCVoltage?
String delivered back: "0.025".
Syntax
:MEAS[:CONT]:AFAN:FREQuency
Parameters
There are no parameters.
Description
Starts a continuous measurement of the frequency of the audio signal applied to the
audio analyzer. To read out the latest measurement result, use the
:FETCh:AFAN:FREQ command.
Note: Any AF test command needs the Audio Option to be installed on your Willtek
4400.
Query
The query form of this command starts the measurement and delivers a string, con-
taining a floating point real number, representing the first measurement result value.
The physical dimension is Hertz (Hz).
Example
:MEAS:CONT:AFAN:FREQuency?
String delivered back: "1000.0".
