Examples
BUS:B1:AUDIO:
BITDELAY 2
sets the bit delay to 2.
BUS:B1:AUDIO:BITDELAY? might return :BUS:B1:AUDIO:BITDEL AY 1
indicating th
at the number of delay bits is 1.
BUS:B<x>:AUDio:BITOrder
Specifies the bit order for the AUDIO bus.
Conditions
This command requires the DPO4AUDIO application module for the
MDO4000/B/C series, or the MDO3AUDIO for MDO3000 series.

Bus
Syntax
BUS:B<x>:AUDio:BITOrder {MSB|LSB}
BUS:B<x>:AUDio:BITOrder?
Arguments
MSB specifies that the most significant bit will be expected first in the order.
LSB specifies that the least significant bit will be expected first in the order.
Examples
BUS:B1:AUDIO:BITORDER LSB sets the bit order to LSB.
BUS:B1:AUDIO:BITORDER? might return :BUS:B1:AUDIO:BITOR DER MSB
indicating that the MSB is first in the bit order.
BUS:B<x>:AUDio:CHANnel:SIZe
Specifies the number of bits per channel for the AUDIO bus. (To specify the
number of bits per word, use BUS:B<x>:AUDio:DATa:SIZe).
NOTE. This command is applicable only for TDM audio bus type
(
BUS:B<x>AUDio :TYPe TDM
)
Conditions
This command requires the DPO4AUDIO application module for the
MDO4000/B/C series, or the MDO3AUDIO for MDO3000 series.

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
