I have no idea G, the DC offset can be longer than 40uS sometimes and once it appears does not diminish that much even though my driving electronics should be still pulsing like mad, so once it's there, it's there no matter what until the conditions are met by a pulse or noise sequence to close it down, It's like I've found a way of turning on a dc gradient tap, i don't believe the energy is coming from my system because it would vary in intensity, so in that case where can the energy be coming from, if i could work out how to trigger on it i might be able to see it more clearly.
What ever is happening i believe it is the reason why i have been getting Dc offset pulses all along, just now i have stumbled on a way of it lasting much longer.
EDIT
Having thought on this some more, There must be a capacitor that's charged, maybe the insulation around the wire conductor, so in that case an event happens that charges the dielectric, holds the charge for a while until the conditions are met to uncharge it. So then the question would be, can the tip of the probe touching the insulation of a wire be enough to form a capacitor of enough capacity to cause the effect seen.To be honest i am not sure if the tip was touching or just laid by, but i can confirm this.
