GETTING STARTED

Step 6 The same TRIG1 key that was used to select the trigger source is also used to select the trigger slope. Repeatedly pressing the TRIG1 button changes the triggering so that it occurs on the leading or trailing edge of the input signal. Note that the slope is also displayed in the bottom text line.

Step 7 For repetitive signals, you obtain a stable display when each successive timebase sweep is triggered at the same stable level of the input signal. You use the TRIGGER LEVEL control to adjust the level. Turn the control. The precise position in relation to the maximum signal amplitude (between +100 % and -100 %) is displayed on the screen.

SUMMARY

The previous steps covered the basic adjustments. Now you are ready to look at the special features of the oscilloscope. This includes the use of the cursors, advanced trigger functions and using the second (delayed) timebase for signal details.
