BUS:B<x>:AUDio:CLOCk:SOUrce?
Arguments
CH<x>
speci fi es an analog channel as the clock source waveform for the audio bus.
CH<x>_D<x>
speci fi es a digital channel as the clock source waveform for the
speci fi ed audio bus.
Math<x>
speci fi es a math waveform as the clock source waveform for the audio
bus.
REF<x>
speci fi es a reference waveform as the clock source waveform for the
audio bus.
REF<x>_D<x>
speci fi es a digital reference waveform as the clock source
waveform for the speci fi ed audio bus.
Examples
BUS:B1:AUDIO:CLOCK:SOURCE CH1_D1
sets D1 of channel 1 as the clock
source for the audio bus.
