Where to start with self-calibration?

[mike3177]

I am interested in calibrating equipment on my own, and I would like to start off by calibrating my own equipment. (I am not talking about becoming accredited/licensed to calibrate other people's equipment, I understand that I would probably need to start off with some NIST traceable calibrated equipment if I wanted to do that.) However, if I were to purchase a used piece of equipment, I would like to be able to do some work on said piece of equipment and be able to say with a certain degree of confidence that it is now calibrated.

Here is a list of my current equipment which was all purchased second hand.

HP 4192A impedance analyzer with 16047A test fixture
HP 8753B VNA with opt 10 and 85047A S Parameter test set
85032B type N calibration kit
HP 3403C RMS voltmeter
Tek 2465B 400 MHz scope
Tek 2232 100 MHz scope
Various probes / test leads / adapters / connectors
Fluke 81 function generator with pulse generator capabilities
Cheap multimeter but I will be picking up a couple of good ones soon
Will also be picking up a couple of variable power supplies soon

If you were me, where would you start? Is there a certain machine that I should calibrate first since its accuracy is more important than the rest? Or will I need to have at least one specific machine professionally calibrated to give me a starting point that I can trust, and if so which machine?

Thanks
Mike

I would suggest downloading the service manuals if you can find them and see for yourself how the machine is calibrated with what equipment and whether it is within your capability.My guess is you will need to spend some money on certain pieces of test equipment. Really read it carefully since you want to learn.
