#182043 - Ground impedance? Responding to: ???'s previous message |
It sounds like a ground bounce problem. If the servo current flows through a non-zero impedance to ground it will raise the 'ground' voltage of the camera. It could be that the display sees this ground voltage added to the video signal. I would make sure that there is a dedicated return signal for the video and that no ground currents flow through it. |
