As you press the D+ or D– softkey (or rotate the Entry knob), the D+
and D– label for the source channel is automatically set and the
channel you select is shown in the upper- right corner of the display
next to "USB".
If you have connected the oscilloscope's analog source channels to the
D+ and D- signals: Adjust the trigger level for each connected analog
channel to the middle of the waveform by pressing the D+ or D- softkey,
then turning the Trigger Level knob.
If you have connected the oscilloscope's digital source channels to the
D+ and D- signals (this applies to MSO model oscilloscopes only): Press
the [Digital] key and select Thresholds to set an appropriate threshold
level for the digital channels.
The value of the trigger level or digital threshold is displayed in the
upper- right corner of the display.
