HP / Agilent seem to have a habbit of changing parts, without changing the part numbers. This is quite a recent experience of this for me. 1) I have a couple of HP verification kits for vector network analyzers (85055A type-N and 85051B APC7). These consists of a couple of airlines, a couple of attenuators, in a wooden box, with foam to hold pieces in place. The foam degrades over time, so I ordered new foam for two kits. While the foam fitted in the bottom of the boxes, it was too small to fit the lid. So I had to make up my own. 2) I contact Agilent and ask if they can selll me the foam to fit the a third verification kit I have - HP 85053B 3.5 mm. The part numbers for the foam are still available, but I think they concluded they would not fit my box. 3) Agilent said I could buy a new box, with the foam that fits. The cost of this was around £350 (GBP) which seemed a bit excessive for a small wooden box with a bit of foam inside. There was nothing wrong with my box, so I declined. 4) Much to my delight, Agilent offer me a box free of charge to keep good customer relations. 5) Box arrives, but the airlines from my verification kit don't fit, as they are too long. So basically Agilent have changed * Size of airlines * Design of box * Size of foam to fit in lid of box all without any change in part numbers!! I've also got a 18 GHz type-N 85054B calibration kit for a VNA. The manual on the Agilent web site, is supposed to cover the serial number of the kit I have, yet the parts list printed on the bottom of the kit is different to the Agilent manual. In this instance they have changed * Part numbers of the sliding loads, although physically they look to be similar or identical. * Part number of the connector gages, which have changed the layout of these a bit, so they don't fit new foam perfectly. It does seem they can make significant changes to parts, without giving them a new part number.
