I have the files to program most TDS700x and TDS600x scopes including TDS520C, TDS520D, TDS620B, TDS640A, TDS644B, TDS654C, TDS680B, TDS684A, TDS684B, TDS684C, TDS694C, TDS744A, TDS754A, TDS784A, TDS754C, TDS784C, TDS754D, TDS784D, and TDS794D. These files were taken from 100% working ok scopes and not downloaded from the internet.
If your scope is not in the list you can message me to see what I can do for you. If you send me your good file, I can load it in.
