HP 8903B which manual to use

[Gmanfro]

Just bought a HP 8903B distortion analyzer serial # 3413A, not sure which manual to use to operate it or do I use both? Seems like the last update stopped at 2450A-2948A and there was a prior one. Seems like there is also a cal manual. This one was just recently calibrated, but want to print a operation manual so I know how to use it properly. Any help on operation or proper manual will be much appreciated.

The service manual is in two volumes, you need both. There is also an operation/calibration manual. My op/cal manual indicates S/N range 2450A to 2922A. I downloaded these from Agilent directly, and I don't know of a source of better quality or later manuals.

Thanks,  Got the op/cal manual and there is 2 service manuals. Looks like I have them located from Agilent. So 3 manuals in total. Guess my brain was overloaded the other day and just got confused. Thanks for straightening things out.
