BUS:B<x>:SPI{:SELect|:SS}:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the source waveform.
D0-D15 specifies a digital channel as the source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
BUS:B<x>:STATE
This command specifies the on/off state of the bus.

SELect:{BUS<x>|B<x>}
Arguments
ON or <NR1> ≠0turnsonthebus.
OFF or <NR1> =0turnsoffthebus.
BUS:B<x>:TYPe
This command specifies (or queries) the bus type. The supported bus types are
dependent on the oscilloscope model and the installed application models. With
the exception of the parallel bus, all bus types require installation of an application
module. (Seepage2-15,Bus Command Group.)
NOTE. The PARallel bus is available on M SO/MDO4000/B models only as well
as MDO3000 and MDO400C models with option MDO3MSO or MDO4MSO
installed.

Commands Listed in Alphabetical Order
HIGH indicates
the bit rate is 480 Mbps.
Examples
BUS:B1:USB:BITRATE FULL sets the bit rate to 12 Mbps.
BUS:B1:USB:BITRATE? might return :BUS:B1:USB:BITRATE LOW,which
indicates that the bit rate is 1.5 Mbps.
BUS:B<x>:USB:PRObe
This command specifies the type of probe connected to the USB bus.
Conditions
This command requires a DPO4USB application module for 4000 series models,
and an MDO3USB application module for MDO3000 series models.
Group
Bus
Syntax
BUS:B<x>:USB:PRObe {DIFFerential|SINGleended}
BUS:B<x>:USB:PRObe?
Arguments
DIFFerential indicates the bus probe is a differential probe.
SINGleended indicates the bus probe is not a differential probe.
Examples
BUS:B1:USB:PROBE DIFFERENTIAL sets the bus probe to differential.
BUS:B1:USB:PROBE? might return :BUS:B1:USB:PROBE SINGLEENDED,
which indicates that the bus probe is not a differential probe.
BUS:B<x>:USB:SOUrce:DIFFerential
This command specifies the source waveform for the USB bus when using a
differential probe.
Conditions
