The TG-1 was a two suitcase affair and each part weighed approximately 80 lbs. The TG-2 was a single piece weighing about 60lbs. Only one generator was needed for a standalone camera or a group of cameras. If there were more than one camera in a given location, the drive and sync signals were looped from CCU to CCU and then terminated at the last CCU in the group.
The sync generator was not a physical part of the switcher. The switcher was a standalone unit of its own. In addition to switching, it provided the intercom functions need for everyone to communicate with each other and also tally light functions for directing the on-camera talent to know which camera was on the air at any given moment.
I hope the above answers your questions. Any more?
