In my thinking the HP 8566B and HP 8668B are what most other analyzers measure up to. In this case the description of a tested working unit at the lowest price I have seen, with lower cost shipping made this a great find. The 8566B came vary well packed and no damage.
I connected it to the display I already had from my 8568B and it worked first try.
Item arrived with considerable cosmetic damage. I have a parts unit that I used to make repairs. Unit works and as best I can tell works perfectly and meets it's specifications. It was very inadequate packaged. It had two handles that were completely broken, two that were bent and mangled the display glass was broken and the tabs that hold the two sections together are broken. I paid quite a bit extra for a freshly calibrated unit and cannot consider it to be calibrated because of the great impact it recieved.
