Hello Don,
I was reading something similar that these were metal foil labels and on
top the clear laminate was attached.
I found old reports that these labels were available for sale to other
people or cal labs from HP and also later Agilent but at some point they
were not sold anymore.
Thanks for the insight about the process done at that time.
Best regards,
Razvan

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 serial no., and the values would be printed on the label and the charted points. Then we put a clear laminate on top of the label, then installed the new label on the power sensor. I haven’t checked but suspect the blank labels may still be available from Keysight, since they are still calibrating the older sensors.
