Hi Altrez,
It is the range.

Once you see the ripples click the up arrow until the range shows Mv like 50MV range, then
Switch to the right arrow for a while. then up again.
Once in range you will get all those.

Unless of course that rms instead of peak to peak etc. is displayed or
the ground dc switch got turned on and the ac is off. That is a toggle with a short pulse with your thumb.

Let me know if it still isn't working,

Ok so all i need to do is turn on the scope. Hit the Div button. Press up until I see the small ripples and then hit left?

I am sure its looking for AC should I change it to look for DC?

Thanks!

I think the second waveform is the most interesting in that, you can see as I tune it in, there are 3 distinct overlapping waves in a braided rope like form and then, with the right adjustments (thanks Jim) I was able to freeze the wave and you can clearly see it.  This amazes me.

Thanks for posting that video. I knew we would all be glad when you got your scope up n running!
Thanks Jim for helping Bill, too.

I get the braided rope too, but when I freeze it, I don't see more than a single wave. I just assumed it was too quick for my eyes.
I think I will go out and see what is happening in the heat of the noonday sun. (Photons with blue sky background are what make it possible for me to catch it on my camera.)

left first only if there is no x axis.
Right after you get the x axis,
Up to get the ripples and up more to get them nice and tall,
then right to see them closer in and spread the wave out a bit.
I get the smooth curve at the 2us spot = all the way to the right. but I cannot start there. There will be no x axis.

I am sure its looking for AC should I change it to look for DC?

No AC is what you DO want.
I was trying to think of the things that have stopped me.
I always check for AC if I am not getting what I think I should get.

The rms instead of peak to peak is also a sure killer.

How do I make sure its not RMS? Is there a way to make sure its peak to peak?

Thank you

There is hardly anything today. I just went out.
I will post my shots in a minute.
The screen will tell you if it is reading rms or peak to peak but you just need to look.
If you still cannot see it after you look closely at your screen, um maybe a pic, but I have a hard time seeing the digital numbers on a pic.

I want to post my pix of today first. This may be just what you are getting too.
