Re: nanovna cases
#enclosure
That case looks really nice. Looks like it will keep a lot more dirt and grime out of the NanoVNA. Looking forward to hearing a price on them I'd be interested if the price isn't too high.

Just knocked up a case this afternoon in the mancave. This case uses the existing screws in the nanovna, so should be easy to pop together like a six piece jigsaw :-) Acrylic/polycarbonate cut with

Re: Can the nanoVNA be used as a scalar spectrum analyzer ?
Thanks Dave, and all the others who answered. Well, I don't need to use the nano as a scalar spectrum analyzer, for this I already have a Rigol. I was just puzzled by the fact that moving the

My NanoVNA-Saver app. on Ubuntu 16.04 identifies /dev/ttyACM0 as the serial connection, but it does not appear to connect. Same NanoVNA runs fine on Win 10. Is this a permission problem, and if so,

Re: Can the nanoVNA be used as a scalar spectrum analyzer ?
For example, the SWR plot is scalar - no sign or complex portion involved. Use the the analyzer's own frequency source, Channel 00, and inspect Channel 01 response. Ignore the sign. You have a scalar

Re: Can the nanoVNA be used as a scalar spectrum analyzer ?
Alberto, The short answer is that the NanoVNA only looks at 101 narrow frequencies evenly spaced from the Start to the Stop frequency. In this case, about every 200kHz. --John Gord

Can the nanoVNA be used as a scalar spectrum analyzer ?
