Sorry, my apologies for not being clear (it's my first time doing anything like this).
Yes I have several X-Y Plotters, two of them do have Time/Sweep in the horizontal plane. What I want is to provide a Ramp signal for all the Plotters, so that the pens can be made to travel from left to right, over a period of time, switchable from one minute to 24 hours, to monitor long-term activity.
The Ramp signal should be just one shot, with a switch to start the sweep, and a switch to reset to zero.
Pen lift does not need to be included.
Hope that this explains it a little bit better.
