I was wondering what is the best way to protect measurement equipment, when handling like oscilloscopes/spectrum analyzers/Vnas/sensitive circuits (especially when stored in (none esd) foam)?

I was thinking of buying end caps for some equipment but not sure what to use. Is it better to use a cap that shorts, has an open, 50ohm terminator or a high resistive value?

  • \$\begingroup\$ I started out thinking that encapsulating the measurement equipment inside a sealed sapphire sphere placed at the center of the Boötes void might be the best way to protect the equipment. Should be pretty safe. But is there anything wrong with a BNC cap? (Or if you have time and/or money, then use a feed-through terminator as a cap.) \$\endgroup\$

  • \$\begingroup\$ @jonk tank you for your comment. I was wondering because I saw an image here where the author had some sort of caps on their usb oscilloscope and not sure what he used and why... \$\endgroup\$

  • \$\begingroup\$ Those may be the feed-through terminators I'd mentioned. \$\endgroup\$

  • \$\begingroup\$ @jonk I'm not sure if they are really feed-thorugh (if you look in this image, you can see the don't have any bnc connector). I found these and they look like the ones used in the images on the PicoScope. Would it make sense for ESD purpose to use terminators on your oscilloscope? \$\endgroup\$
