BUS:B<x>:AUDi
o:CHANnel:SIZe <NR1>
BUS:B<x>:AUDio:CHANnel:SIZe?
Arguments
<NR1> specifies the number of bits per channel.
Examples
BUS:B1:AUDIO:CHANNEL:SIZE 8 sets the number of bits per channel to 8.
BUS:B1:AUDIO:CHANNEL:SIZE? might return

BUS:B<x>:AUDio:CLOCk:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the clock source waveform for the audio
bus.
D0-D15 specifies a digital channel as the clock source waveform for the audio
bus. (MSO/MDO4000/B models only as well as MDO3000 and MDO4000C
models with option MDO3MSO or MDO4MSO installed.)
Examples
BUS:B1:AUDIO:CLOCK:SOURCE D1 sets D1 as the clock source for the audio
bus.
BUS:B1:AUDIO:CLOCK:SOURCE? might return
:BUS:B1:AUDIO:CLOCK:SOURCE CH1 indicating that the clock source is
set to CH1.
BUS:B<x>:AUDio:DATa:POLarity
Specifies the data polarity for the AUDIO bus.
Conditions
