"USB High speed"
Selects USB high-speed protocol (480 Mbit/s). As the signal is differ-
ential, there is only one source and one threshold to be defined.

Remote command:

D+, D-
Define the source settings for the D+ and the D- data signals for USB low speed and
USB full speed protocols.
Usually, the source is one of the analog channels. Reference and math waveforms are
available as source if the trigger source is one of the analog channels but not the serial
bus.

Differential
Defines the source settings for the differential data signal (in USB high-speed protocol,
only). You can select analog channels "C1" to "C4", and also active math and refer-
ence waveforms as source. If you want to trigger on the serial bus, analog channel
sources are required.
