BUS:B<x>:AUD
io:DATa:SIZe
Specifies the number of bits per word for the AUDIO bus.
NOTE. The number of bits specified for this command must be always
less than or
equal to the number of bits per channel (set using
BUS:B<x>:AUDio:CHANnel:SIZe).
Conditions
This command requires DPO4AUDIO application module for the
MDO4000/B
/C series, and MDO3AUDIO for MDO3000 series.
