Programming a Decoded Audio Measurement

June 2, 1999
This section provides an example of how to make a Decoded Audio (DAUDio) measurement. The following
procedure assumes that an active link is established between the test set and the mobile station. See
"Establishing an Active Link with the Mobile Station" on page
1. Configure decoded audio measurement parameters using the SETup subsystem.
2. Setup the audio source to stimulate the MS with a pulsed audio signal.
3. Start the decoded audio measurement using the INITiate subsystem.
4. Use the INITiate:DONE? command to find out if decoded audio measurement results are available.
5. Use the FETCh? command to obtain decoded audio measurement results.

Programming Example

10 OUTPUT 714;"SETUP:DAUDIO:CONTINUOUS OFF"
20
30 OUTPUT 714;"AFGENERATOR:PULSE:STATE ON"
40 OUTPUT 714;"AFGENERATOR:VOLTAGE:SAMPLITUDE 100MV"
50 OUTPUT 714;"AFGENERATOR:FREQUENCY 2.1KHZ"
60 OUTPUT 714;"SETUP:DAUDIO:FILTER:SFREQUENCY 2.1KHZ"! Specifies the tunable
70
80
90 OUTPUT 714;"INITIATE:DAUDIO"
100 REPEAT
110 OUTPUT 714;"INITIATE:DONE?"
120 ENTER 714;Meas_complete$
130 UNTIL Meas_complete$="DAUD"
140 OUTPUT 714;"FETCH:DAUDIO?"
150 ENTER 714;Ingerity,Decoded_audio
160 END

Returned Values

The measurements returned by this program are:
• Integrity returns the measurement
measurement with no errors).
• Decoded_audio returns the decoded audio measurement results in percent (%).
