Before proceeding to the next step, make sure that you
have recorded the oscilloscope calibrator voltage levels for
each of the threshold settings shown in
9 When testing 3000 X- Series MSOs, use the 8- by- 2 test
connector to connect digital channels D15- D8 to the
output of the oscilloscope calibrator. Then connect the
D15- D8 ground lead to the ground side of the 8- by- 2
connector.
10 Repeat this procedure (steps 6 through 8) for digital
channels D15- D8 to verify threshold accuracy and record
the threshold levels in the Performance Test Record (see
63). Be sure to set the thresholds with the User
page
softkey for the appropriate set of channels.
