Re: Shipping overseas?
Maybe. Ship printed circuit boards to Germany, from the U.S., using a 'Priority Mail International Flat Rate' medium box. (or small, or large too) AFIK, you gotta use customs form 'PS Form 2976-A' On

Re: HP8510C TRL Calibration
I note the HP8510C driver, so i should be able to use this to access the 'switch terms. Also i'm interested to see how fast it reads the s-parameters! Thank you for this, N

Re: HP8510C TRL Calibration
However, when i run from the PC and file data, the first line in the s2p file is: !HP8510C.07.14: Aug 26 ?1998, so that indicates a different software version. (well the monitor is CRT, so pretty

Re: HP8510C TRL Calibration
I've been looking at scikit-rf to do the TRL calibration and it mentions using the 'switch terms' to improve the calibration. I'm just wondering, how do i read the switch terms from the HP8510C, which

Re: Shipping overseas?
Hey, in the past, I used Stackry and was happy with their service. MyUS was also great when it came to handling and shipping but their small print can inflate your budget. This is 5 yr old

Yep, I have seen the fireworks in the lab, too. Been a while, fortunately. More than 25 years ago we had a technician who installed a few tant caps backwards into a VMEbus chassis. Blam, molten

Hey again, Here are the photos. The one with the big blob is the blown one. It does melt with the iron so it's indeed solder. Thanks for the info on possible replacements.
