Function

Returns a comma-separated list of the generated frequency for each frequency point (see SETup:SAUDio:FREQuency:POINts ).

When you specify the start frequency, stop frequency, and the number of measurement points, the test set calculates the intermediate frequencies that are generated. You cannot directly set the intermediate frequencies using this command, you can only query them.

Query

Range: up to 60 comma separated values

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:FREQUENCY:VALUE?" !Queries the list of generated frequencies.

Function

Sets/queries the number of evenly-spaced frequency points in the sweep. If this value is set to 1, only the start frequency is used in the sweep.

Setting

Range: 1 to 60

Query

Range: 1 to 60

*RST Setting

5

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:FREQUENCY:POINTS 20" !Make audio measurements at 20 frequency points in the sweep.

Function

Sets/queries the frequency at which to begin the sweep. The default units are Hz.

It is possible to set the start frequency higher than the stop frequency. If this is done, the sweep starts at the higher frequency and stops at the lower frequency.

Setting

Range: 300.0 to 15000.0 Hz

Query

Range: 300.0 to 15000.0 Hz

*RST Setting

300 Hz

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:FREQUENCY:START 450HZ" !Start the frequency sweep at 450 Hz.

Function

Sets/queries the frequency at which to end the sweep. The default units are Hz.

It is possible to set the stop frequency lower than the start frequency. If this is done, the sweep starts at the higher frequency and stops at the lower frequency.

Setting

Range: 300.0 to 15000.0 Hz

Query

Range: 300.0 to 15000.0 Hz

*RST Setting

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:FREQUENCY:STOP 1500HZ" !Stop the frequency sweep at 1500 Hz.

Function

Queries the total multi-measurement count. This is equal to the number of frequency points in the sweep multiplied by the multi-measurement count set for the swept audio measurement.

*RST Setting

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:ICOUNT:MAXIMUM?" !Queries the total number of measurements made.

Function

Sets/queries the expected peak voltage of the swept audio measurement. This determines the range and resolution of the sampled voltage values.

Setting

Resolution: 1 mV

Query

Range: 1 mV to 20 V

*RST Setting

20 V peak

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:PEAK:VOLTAGE 5V"

Function

Sets/queries how long swept audio measurements wait to start an audio measurement after setting the audio source's frequency. A setting of 0.0 seconds let's swept audio measurements run at maximum speed.

Settling time may be needed when testing a device that has a time delay through the audio path. Path delays can cause the audio generator's signal to change frequencies before the output signal can be analyzed at that frequency. Specifying a settling time ensures that the audio generator stays at each frequency point long enough for the audio analyzer to correctly measure the device's audio output.

Setting

Range: 0.0 to 999 ms

Resolution: 1 ms

Query

Range: 0.0 to 999 ms

*RST Setting

0 ms

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:SETTLING:TIME 20MS"

Function

Sets/queries whether SINAD and distortion measurements are enabled. Turning on SINAD/Distortion measurements will cause the swept audio measurement to run significantly slower because of added sampling and calculation times.

*RST Setting

0 (off)

Programming Example

 
OUTPUT 714;"SETUP:SAUDIO:SDISTORTION:STATE ON"
