In this video we get another step closer to doing a calibration/alignment on the 7854 frame. I address the issue of ROM ROT that these scopes suffer from just given their age. The 7854 being the first sampling scope that I am aware of I would like to get one up and running totally for the lab but I have confirmed that both of my units are out of spec when It comes to their alignments. Therefore they both need work.
