This chapter describes how to use the digital channels of a Mixed-Signal
Oscilloscope (MSO).
The digital channels are enabled on MSOX3000T X-Series models and
DSOX3000T X-Series models that have the MSO upgrade license installed.
To connect the digital probes to the device under test
1 If necessary, turn off the power supply to the device under test.
Turning off power to the device under test would only prevent damage that
might occur if you accidentally short two lines together while connecting
probes. You can leave the oscilloscope powered on because no voltage appears
at the probes.
