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 .
