Last updated: December 3, 2008

SYSTem:AUDio:OUTPut:SOURce

Function

GSM TA

Set/queries whether the audio generator signal or the FM demodulation signal is selected to be routed to the AUDIO OUT port of the test set's front panel.

When audio generator is selected for output at the front-panel AUDIO OUT port, use AFGenerator Subsystem to control the audio generator.

NOTE

The selection of FM Demod signal is useful only in AMPS system. A bandpass filter, expander circuit, and deemphasis circuit can be individually inserted or bypassed in the FM Demod signal path. Use the command SYSTem:AUDio:OUTPut:FMDemod:BPFilter:STATe to insert the bandpass filter. Use the command SYSTem:AUDio:OUTPut:FMDemod:EXPandor:STATe to insert the expandor circuit. Use the command SYSTem:AUDio:OUTPut:FMDemod:DEEMphasis:STAT to insert the deemphasis filter.

NOTE

There will be no guaranteed performance for the signal present at the Audio Out port when FM Demod is selected for output.

! Selects FM Demod signal for output at the front panel AUDIO OUT port.

SYSTem:AUDio:OUTPut:FMDemod:BPFilter:STATe

Function	GSM TA	Sets/queries whether the fixed bandpass filter is inserted or bypassed in the FM Demod signal path. It is useful only when FM Demod signal is selected for output at the front-panel AUDIO OUT port (see SYSTem:AUDio:OUTPut:SOURce ). When the state is ON, a 300 Hz to 3 KHz bandpass filter is inserted in the audio signal path. When the state is OFF, the bandpass filter is bypassed in the audio signal path

SYSTem:AUDio:OUTPut:FMDemod:EXPandor:STATe

Function	GSM TA	Sets/queries whether the expandor filter is inserted or bypassed in the FM Demod signal path. It is useful only when FM Demod signal is selected for output at the front-panel AUDIO OUT port (see SYSTem:AUDio:OUTPut:SOURce ). When the state is ON, the expandor filter is inserted in the audio signal path. When the state is OFF, the expandor filter is bypassed in the audio signal path.

It is useful only when FM Demod signal is selected for output at the front-panel AUDIO OUT port (see SYSTem:AUDio:OUTPut:SOURce ). When the state is ON, the deemphasis filter is inserted in the audio signal path. When the state is OFF, the deemphasis filter is bypassed in the audio signal path.
