Too bad we don't have a halscope button to AC couple a channel.
Looking at the velocity output of the encoder, at 300 revs, its so
close to a flat line that at maximum gain and offset which still
puts the active trace on screen, its one pixel from a flat line, so
low its not possible to see an encoder quadrature cyclic error. This
is going to work a heck of a lot better.
HALScope has an AC coupled input option, better still, it has a input
offset option that does not suffer the AC modes baseline wander
Where do I find that, Peter? It hasn't nibbled on my conscious yet...
Its on the "Offset" popup
