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
This command requires the DPO4AUDIO application module for the
MDO4000/B/C series, or the MDO3AUDIO for MDO3000 series.

Syntax
BUS:B<x>:AUDio:DATa:POLarity {NORMal|INVERTed}
BUS:B<x>:AUDio:DATa:POLarity?
Arguments
NORMal specifies positive data polarity for the audio bus.
INVERTed specifies negative data polarity for the audio bus.
Examples
BUS:B1:AUDIO:DATA:POLARITY INVERTed sets the data polarity to Inverted.
BUS:B1:AUDIO:DATA:POLARITY? might return
:BUS:B1:AUDIO:DATA:POLARITY NORMAL indicating that the data polarity is
set to Normal.
