2 Testing Performance
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 Figure 2.
