The 30MHz calibrator output on the 8553B from the 141T system was intentionally rough to give you a series of markers to calibrate to. FWIW, Dave Wise...
The large response at 3 MHz may actually be the zero Hz response that all analyzers provide. It would not be unusual (probably even in spec) to be off by 3 MHz...
I'm always impressed by brave souls who buy kilobuck+ instruments and open the cabinet to "fix" them before opening the manual. Wish I had that kind of nerve....
