are all at digital high levels. Record the oscilloscope calibrator voltage in the
Performance Test Record (see page 46 ).
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 Table 5 .
9 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 7 and 8) for digital channels D15-D8 to verify
threshold accuracy and record the threshold levels in the Performance Test
Record (see page 46 ).
