The Harris analog has a Glitch in the video. It appears like light specks moving from left to right. It is?intermittent.
The suspect is the video module in Exciter at this time.
The other possibility is the flywheel sync circuit tipping the vertical interval there is a pot to adjust this.
The contact at Harris is Robert Spawn for these exciters.
A test setup on wheels needs to be installed as the exciter is across the room from the test rack.
Also a new video cable (or re-crimp ends) for video input.
