tinyPFA high accuracy settings

[@paulcohen1555]

WOW! So much in this small package!

[@germanjohn5626]

The first thing that came to my mind was holy shit.... Thanks Eric, well done

[@sq7dqx]

Erik - your contribution to education of electronic or ham radio oriented youth and oldies is unbleiveable! I bow my head and salute! Is that software will work with other palm size VNA's?

[@ErikKaashoek]

No, only nanoVNA-H4

[@VasyVasii]

Tinypfa does not support high signal levels, I use the GPSDO as a reference, for synchronization up to 1 Hz the frequency meter PLJ-8LED, and up to 0.01Hz (10ppb) the oscilloscope, anyway, the sources I use are not below 20 ppb stability for 10 minutes

[@ErikKaashoek]

@@VasyVasii I always use 20dB external attention at each input. With this you can use sources up to 20dBm

Thank you

[@SeAfasia]

Nice firmware...thanks for posting your infos...

[@ErwinSerle]

What signals do you provide on the ports and from what external equipment Erik ?

[@ErikKaashoek]

See www.tinydevices.org/wiki/pmwiki.php?n=TinyPFA.FirstUse The source does not matter a lot, as long as its fairly stable I was using a two output 16 bit DDS based signal generator

[@johnwest7993]

Are other versions of the NanoVNA also getting firmware to do this, or are they not hardware compatible with the code you are implementing?

[@ErikKaashoek]

Can only be implemented on nanoVNA-H4
