Then bring in an AM signal, set the scope timebase on 10 uS per division ( to have about 10 cycles of AM per division), and adjust the Trigger Level. If you see nothing, some scopes has "AUTO" setting where no triggering is needed; try AUTO. And change the TimeBase to 20 or 50 or 100 uS per division, where you will see 1KHz of voice/music modulation across the entire (10?) horizontal divisions of the display. | |
