Fundamentally, the 182T is a 182A with longer persistence tube to help with slower spectrum analyser scans and somewhat different BNC outputs on the rear (which never really get used anyway). I do mean longer persistence and not a storage tube. If you want storage, the 184A could be used at the expense of a smaller display and the likelihood that the tube has been knackered by inexperienced users. The 853A spectrum analyser mainframe adds digital storage but will not take 'scope plug-ins.

BTW, you mentioned the calibrator readings being off, but did not say how you are measuring them. Can we assume that you are just looking at them on screen using the appropriate 'scope plug-ins? If so, are they decent square waves (once any 'scope probe has been compensated for that plug-in?
