Using "Z" Mod on a scope.

[Murphyv310]

Hi David.
The circuit I'm using is a "Ramp" generator, the reset is tied to +B for free running, the BC557 supplies constant current. Negative going sync is fed to pin 5.
All electronic standards can be resolved as can some of the electronic/mechanical hybrid standards (240/25p & 180/25p)









As can be seen there is some distortion on the lower part of the scan, more so on 25p (25Hz) than on the interlaced systems.
Also there is a problem with the stored image on 240/25p, I'll look for a suitable test card of the time.
All a bit of fun but none the less successful.
