GPIB Command Conventions

AFGenerator:COUPling

Function

 Sets the output of the audio generator to be ac or dc coupled to the front-panel AUDIO OUT port.
Setting

Range: AC or DC
Query

Range: AC|DC
*RST setting DC

Requirements

Test or Lab Application Revision: A.01 and above

Programming Example

 
OUTPUT 714;"AFGENERATOR:COUPling AC" !Sets the audio generator coupling to AC.

AFGenerator:FREQuency

Function

 Sets/queries the frequency of the audio generator. The units (HZ|KHZ|MHZ|GHZ) are optional. If no units are specified, then units default to HZ.
Setting

Range: 1 Hz to 20 kHz

Resolution: 0.1 HZ
Query

Range: 1 Hz to 20 kHz

Resolution: 0.1 Hz
*RST setting 1 kHz

Requirements

Test or Lab Application Revision: A.01 and above

Programming Example

 
OUTPUT 714;"AFGENERATOR:FREQUENCY 1000" !Sets the audio generator frequency to 1000 Hz.

AFGenerator:PULSe[:STATe]

Function

Sets/queries the audio generator pulse state.

The pulse state must be on when the test set's audio generator is used for audio stimulation during a decoded audio measurement.

When the state is on, the audio signal from the test set is pulsed at a 10 Hz rate with a 50% duty cycle.

Setting Range: 0 | OFF | 1 |ON

Query

Range: 0|1
*RST setting 0 (off)

Requirements

Test or Lab Application Revision: A.01 and above

Programming Example

 
OUTPUT 714;"AFGENERATOR:PULSE ON" !Sets the audio generator pulse to ON.

AFGenerator:VOLTage[:SAMPlitude]

Function

 Sets /queries the amplitude of the audio generator in volts and turns the state to on. The units (V|mV) are optional. If no units are specified, then units default to V.
Setting

Range: 0 to 9 V pk.

Resolution:

  • 0.5 mV pk. <= 1 V pk. output
  • 5 mV pk. > 1 V pk. output
Query

Range: 0 to 9 V pk.

Resolution:

  • 0.5 mV pk. <= 1 V pk. output
  • 5 mV pk. > 1 V pk. output
*RST setting 0 V

Requirements

Test or Lab Application Revision: A.01 and above

Programming Example

 
OUTPUT 714;"AFGENERATOR:VOLTAGE 2.1" !Sets the state to on and the output
                                     !voltage to 2.1 volts.

AFGenerator:VOLTage:AMPlitude

Function

 Sets/queries the amplitude for the audio generator when the audio generator state is on. The units (V|mV) are optional. If no units are specified, then units default to V.
Setting

Range: 0 to 9 V pk.

Resolution:

  • 0.5 mV pk. <= 1 V pk. output
  • 5 mV pk. > 1 V pk. output
Query

Range: 0 to 9 V pk.

Resolution:

  • 0.5 mV pk. <= 1 V pk. output
  • 5 mV pk. > 1 V pk. output
*RST setting 0 V

Requirements

Test or Lab Application Revision: A.01 and above

Programming Example

 
OUTPUT 714;"AFGENERATOR:VOLTAGE:AMPLITUDE 1.414" !Sets the audio generator output
                                                 !voltage to 1.414 volts peak.

AFGenerator:VOLTage:STATe

Function

 Sets/queries the audio generator state
Setting 0 | OFF | 1 |ON

Query

0|1
*RST setting 0 (off)

Requirements

Test or Lab Application Revision: A.01 and above

Programming Example

 
OUTPUT 714;"AFGENERATOR:VOLTAGE:STATE ON" !Set the audio generator state to ON.
