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.
