Re: HP 3456A repair/restore
Getting pretty intermittent time for this, and mostly reading time, rather than bench, I've been studying a bit the calibration procedure (the meter seems to be about 25ppm high at 10V). I searched a

Re: Power Sensor Calibration Labels
Back in the 1990’s we calibrated power sensors, all of them but the 50GHz ones, we used metal foil HP labels (2 types - long and short) using an other brand printer (about 4”w x 6”h x 8”d) the

Re: Power Sensor Calibration Labels
As explained already, the dimensions of the labels are specially made for HPAK with a reference that I cannot indicate here. They are used for the following sensors : N848X : 28 x 88 mm 848X : 28 x

Re: 8566B Performance Verification with 8620C
You might as well upload to both unless someone complains :) Another option for a sweeper is the synthesised HP 83752A from the 1990s. These only cover up to 20 GHz but they can be found for sensible

Re: Power Sensor Calibration Labels
I have been using GALVA for many years to make custom labels. The results are limited by your imagination and the print stock that you can buy. An example of a replacement of a damaged label for a

Re: Power Sensor Calibration Labels
I have the older and smaller models that can only print up to 18mm. I see the new ones can print up to ~1" but I guess the tapes are the 24mm ones. I wanted to get something as close as possible to

Regarding older 8566 performance verification procedures: for those interested I have uploaded my scan of the 8566A performance verification. Fun to compare equipment requirements to the well known

Re: HP - a summary of what went wrong.
Yes, that book is great. The chapter where Carly is late for dinner at Bill Hewlett's is priceless and tells volumes about the differences between their two management styles. There is also a story

Re: Power Sensor Calibration Labels
I attached 4 pictures with the labels. These are from the late 80's. Are you sure they are made with a plotter? Also they seem to have a plastic foil on top, non-glossy one on my labels. I have one

Re: Power Sensor Calibration Labels
For the picture sent, we can see easily that it was printed (plotted) with a plotter from the 747XA family. Few years ago (2020's), it was used a Brady printer with Polyester labels specially made (95

Re: HP 3456A repair/restore
The BAMA library has a manual version with the missing pages - the "high res" version. But that's the only one. So for anyone looking for those, that's where to find them.

Re: Tool to remove "fancy" BNC nut (0590-1251)
I've always used an adjustable wrench with pristine jaws and a sheet of paper cut out to not mar the front panel, then press down so the wrench doesn't slip up the rounded edges.? It's always worked
