You may select Low Speed (1.5 Mb/s) or Full Speed (12 Mb/s).
8 Press the D+ and D– softkeys to select the channel connected to the USB signal
D+ and D– lines. The D+ and D– labels for the source channels are
automatically set.
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.
