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.
