[GreenKeys] CRT Question

[Keith Densmore]

Time for another question......
My Dovetron  MPC  1000 has an LED crosshair tuning display, which works just 
fine but.....
I have a couple of spare 
o'scopes here and I really like the kind of display that shows mark/space and noise. Tuning is correct when the display shows vertical/horizontal tuning of mark/space

.
This type of display was used on some older TU's 
I have seen and that tuning method is also used on MMTY.

Question is how is that type of display wired into a terminal unit?  
It's no problem picking off mark/space pulses but how do you make them display as the 'ball 
of noise'?

Thanks,
Keith
