BUS:B<x>:AUD
io:WORDSel:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the word select source waveform .
D0-D15 specifies a digital channel as the word select source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
Examples
BUS:B1:AUDIO:WORDSEL:SOURCE CH1 sets CH1 as the word select source.
BUS:B1:AUDIO:WORDSEL:SOURCE? might return
:BUS:B1:AUDIO:WORDSEL:SOURCE CH2 indicating that the word select source
is set to CH2.
BUS:B<x>:CAN:BITRate
Specifies the bit rate for the CAN bus.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application
module for all 4000 series models, or the MDO3AUTO application module for
MDO3000 series models.
Group
Bus
Syntax
BUS:B<x>:CAN:BITRate <NR1>
BUS:B<x>:CAN:BITRate?
Arguments
<NR1> is the bit rate. The instrument supports bit rates at 10 bps intervals. You
can enter any positive integer
, and the instrument will coerce the value to the
closest supported bit rate.
Returns
The query always returns the numerical bit rate value.
Examples
bus:b1:can:bitrate 50000 sets the CAN bit rate to 50000.
bus:b1:can:bitrate? might return :BUS:B1:CAN: BITRATE 50000
indicating the bit rate is set to 50K.
