Long story short, I have a synchro bearing repeater (active, with amp) which was rebuilt. The aligment is unknown. I have digital synchro simulation device, reference generator, all good and ready to do aligment. But the designators for reference are like this: simulator "RH" and "RL", bearing repeater "Com" and "Line".
So the question is, do you think RH = Com and RL = Line, or vise versa? Obviously, if I connect wrong, I will align the device 180 deg off. In some sources they also use "R1" and "R2" as reference designators.
I hate this nomenclature and I hate these synchro systems, built before I was even born (really needed to vent).
