I have just learned what the ref save and recall does and was wondering if there was any way to reposition the image or do I continue to setup the trace in the position I want the reference image to be displayed.The reference waveform is simply a kind of screenshot of a trace. You can't do anything with it other than look at it, afaik.
can you explain to me what to look for in the schematic that shows a strong DC offset?The current direction through the transformer is always the same, thus the net DC flux in the transformer's core.
Soft ferrites are not permanently effected by heat (unless you go to the extremes near 1000 C). They however have a relatively low curie temperature and thus don't work as long as they are hot (e.g. > 150 C). This effect is however reversible. The air gap can be a big issue - there would have been a spacer that is not much different from the glue.It's certainly not as much as 1000oC as I've seen cooked transformers with useless cores and no way they heated up that much while having bobbin remaining in one piece or FR-4 PCB not catching flames under toroidal one. But it's not 160oC either.
In therory there could be flybacl transformers with a permanent magnet premagnetization, that could be effected by heat. However I have not seen such a thing, except for linearity correction with CRTs. So I doubt one would find it in more normal PC supply - though they would do all kind of tricks to save a few cents.
For all my projects based on Atmel ATF150x CPLDs I successfully use a homemade 'ByteBlasterMV' programming cable (on parallel port) in conjunction to the program ATMISP version 6.7.

P.S.
I program .JEDs instead of SVFs
It is possible that it is compatible with PSG9080. If so, then can be used my tool: https://github.com/qrp73/PSG9080_ARBThis looks like a good instrument! Alltough its not so cheap, i consider getting it.
