Tutorial

D.Locate the controls in the SYNC box of the Analyzer. Verify that the

AUTO SEARCH function is ENABLED. The LED in the AUTO SEARCH key should be ON.

If the LED is OFF, press the AUTO SEARCH function one time to turn the ON. At this point, verify that the green LOCK LED is ON.

The Analyzer will now search and calculate a new data threshold. What is the value of the threshold selected by Auto-Search? You should expect to see this threshold value within a few hundred millivolts of the “data signal mid-point (or optimum threshold).

Note - Common Setup Problems

∙Connecting the Generator’s clock output to the Analyzer’s not-clock (clock- bar) input

∙Connecting the Generator’s data output to the Analyzer’s not-data (data-bar) input

∙Changing Generator’s CLOCK amplitude/offset when lab calls for adjustments to DATA signals

∙Failure to connect the external DATA THRESHOLD cable from rear of unit to NOT_DATA input.
