Synchro1, you are just embarrassing yourself.  TinselKoala's device generates nice, pure, smooth, sine waves.  There is no abrupt/violent redirection of current, voltage spike, etc.

Tinselkoala's scope is not showing the 90 degree phase shifted reactive power from the field collapse.

There is really something wrong with you.

Still learning scopes as you know-but why the DC coupling on an AC system?
And what scope program is that one your using,or do you need a cpu scope card aswell?

Tinselkoala,


Very nice scope shot! We're discussing serial events of charge, field collapse and reactive power that are graphically depicted in two dimensions on the scope. In three dimensions the second sine wave at 90 degrees would produce a blinding flash of light from the A.C. field collapse flyback. This is a negative micro henry, because  consumption is positive, so power input measures negative.

The second question is simple. The display is from the generously donated Link 2100 DSO, which uses the PC as its display/control interface. It is similar to the modern Hantek scope that I have recommended several times to beginning DSO users. Unfortunately the Link's math is very limited, it cannot do trace multiplication. I think the Hantek can, though.

The first question.
AC versus DC coupling is the most misunderstood feature of scoposcopy by far. 
All the "AC coupling" function does is to put a capacitor, usually 0.1 microFarad or so, in strict series with the probe's input lead. That is all it does. Period. The "DC coupled" setting is Direct Coupled, duh, without the capacitor.
Now, what effect does this have on the measurements you make with the scope? It should be obvious to you: the capacitor does not permit DC to pass, but it does permit AC to pass. So it effectively _removes_ any DC offset to an oscillating signal, and brings the _average_ of the oscillating part down to the zero reference of the scope's channel. This of course wreaks havok with almost all trace math and measurements, except for p-p amplitudes. You lose the DC offset information and the true amplitude of peak voltages when you use "AC coupled" settings.
OK, what are they for then?
The most often-used reason for AC coupling is to look at small ripples riding on top of large DC offset voltages. If you are DC-coupled and simply select high amplification settings on the vertical control, the DC offset will take your trace off the screen and you may not be able to move it back down with the vertical position controls... and you already know what your DC offset is anyhow. So you select "AC coupled" and bingo! The whole DC component is blocked, your vertical position control stays centered and the _average_ of the Ripple Only is now moved to your trace reference baseline position.

Now-- consider the times we have seen people making claims about power when one or more of their scope measurement came from a channel that is AC-coupled. You could literally have any amount of DC power flowing as offset, and you would never see it.
