1) Exactly what probe are you setting to 75 ohms? Is this a scope input setting?
2) What do you mean by "fall in the correct place?" If the procedure says min or max at the marker, it means only that - the vertical position of the marker should be min or max. If the curve ends up looking wrong *at the end after all adjustments have been made*, there is something wrong with your setup or you made a mistake earlier in the procedure.
It is possible the curve won't look right when you are only part way done.
