Picard TipsPicard management tip: Don't negotiate absurd schedules with engineers. Encourage truth telling and reasonable time estimates.
yeah the silicone caps are totally on another scale, both in price but also in tolerance and repeatability. I think Vishay also offered some reflow solberable ones a while ago but they were discontinued. Accu-P would also be my go-to if price isn't an issue. There are also some very high frequency low C caps that intentionally use miniscule amount of lossy dielectrics (X7R et al.) to avoid sharp resonances due to the package parasitics (DLI, I think there under the Knowles brand know)

Darrell HarmonRohde&Schwarz NRP-Zxx USB power sensors are not USB TMC but something undocumented and cursed.
You send it null terminated SCPI commands chunked into 16 byte pieces and 0 padded as USB bulk.
It sends back 16 byte USB bulk, byte 0 indicates what it is which can be a status, a little endian single precision float, 10 bytes of string or an indication that it's done sending a string.
Picard management tip: Even without game-changing results, experimentation is time well spent.
