1 Turn on the test equipment and the oscilloscope. Let
them warm up for 30 minutes before starting the test.
2 Set up the oscilloscope calibrator.
a Set the oscilloscope calibrator to provide a DC offset
voltage at the Channel 1 output.
b Use the multimeter to monitor the oscilloscope
calibrator DC output voltage.
3 Use the 8- by- 2 test connector and the BNC cable
assembly to connect digital channels D0- D7 to one side of
the BNC Tee. Then connect the D0- D7 ground lead to the
ground side of the 8- by- 2 connector. See
