BUS:B<x>:USB:
SOUrce:DIFFerential
{CH1|CH2|CH3|CH4|MATH|REF1|REF2|REF3|R EF4}
BUS:B<x>:USB
:SOUrce:DIFFerential?
Arguments
CH1–4 specifies an analog waveform as the source. This channel should have
an attached differential probe.
MATH specifies the math waveform as the source.
REF1–4 specifies a reference waveform as the source.
Examples
BUS:B1:USB:SOURCE:DIFFERENTIAL CH2 sets the source to channel 2. You
should have a differential probe attached to channel 2 and connect it to the USB
data signal.
BUS:B1:USB:SOURCE:DIFFERENTIAL? might return
:BUS:B1:USB:SOURCE:DIFFERENTIAL CH4 indicating that channel 4 is
the source.
BUS:B<x>:USB:SOUrce:DMINus
This command specifies the source for the USB bus D- input. If you are using
single-ended probes, you need to set the sources for both the D+ and D- inputs.
Conditions
This command requires a DPO4USB application module for 4000 series models,
and an MDO3USB application module for MDO3000 series models.

|D9|D10|D11|D12|D13|D14|D15}
BUS:B<x>:USB:SOUrce:DMINus?
Arguments
CH1–CH4 specifies an analog channel as the source waveform for the D- input.
D0-D15 specifies a digital channel as the source waveform for the D- input.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
