I have an HP 8656B that I picked up. It had a problem which I fixed, but I can't really tell how well it is working and if it is up to spec.
My limited gear can confirm basic functionality, but nowhere near good enough to give me an accurate indication. Things look OK on the scope, but I can't measure frequency accurately (yet) let alone check attenuator accuracy or distortion - and I don't have any means to check its communication abilities.
It's more kit than my bench and anticipated needs will require, and since it could probably command a fair price, it is destined for sale. As such, while I want to maximise the sale price, I don't want to misrepresent the item.
SO ... what would you do? Calibrate? Not calibrate? Sell as is, showing what testing I have been able to perform?
... and if to calibrate - where would be the place to go in Sydney (preferably western suburbs)?
