For some reason my scope will not trigger on the output of my audio amplifier - I see no signal from it at all. I could not figure out the problem. It works with earbuds and is loud, but when I connect my probe to one of the channels there is no signal. It worked fine yesterday.
I played with settings a bit anyway and single trigger works only with one event, and to capture additional events is cumbersome to get a zoom view after.
Normal trigger does not allow enough delay to see the second signal. When you try to offset, the delay jumps from 10s to 5s, and then you have to zoom out.
I have not played much with zoom mode, but that does let you offset the signal enough, but then zoom is limited. This might work.
The period is actually closer to 13.5s, so I had sweep set to 2s/div and yes it does show 500kS/s, so resolution is half what I thought.
Well, I'm kind of back to the higher level problem of detecting the signal I want, a quiet click sound.
