Using "Z" Mod on a scope.

[`FRANK.C]

Hi.
Fitted a better CRT today and modified a function generator I got from a member here a few weeks ago for a sync input.
On the triangular output and synced up the linearity is reasonable, but no interlace, hardly a problem on the scope screen.
Next is to make a sync separator for composite video sources.

Hi Trevor

It's looking good.
If you wanted interlace you could try syncing to the falling edge of the field sync pulse you should get interlace as this edge varies by a half line for odd and even fields. But that edge occurs towards the end of the field blanking period so not ideal to sync off.
