Re: Erratic results on nanoVNASaver ?
Id like to try saver, but when I looked in the Git repo, the Win 64 dl link was not anywhere to be found. Is there a copy of it here in the group files, or maybe someone has a link that works? Steve

It seems reasonable to move there, but maybe a bit later) Thanks for suggestions! Merry Christmas! -- Alex

Export the file from the NanoVNA-F V2 #applications
I purchased the NanoVNA-F V2 and downloaded the NanoVNA-saver. I wanna use the VNA without connection with PC during measurements. So, I saved the s2p file to select "storage"->"S2P". It is possible

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Just want to mention that it is awesome that I have suddenly a phase noise and ADEV analyser in house! Thanks for this christmas gift, Erik! Your work is awesome! I use the Symmetricon/Microsemi

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Yes, there is a way to go get rid of this bump Shall we move this subject to the tinypfa support forum as this subject is of interest for all future users.

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Definitely, NOT! But what's about the mid-time range on ADEV (approximately after 10...100 s there is a noise bump, possibly caused by some internal drifts?) 1E-14 seems to be a long-term limit for

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Hi Erik, Thank you for making this firmware available! Is there a way to calibrate the reference by software? There is no NULL A FREQ menu. I installed the FW dated 2022-12-19. Thank you again! Best

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
The TAPR TICC is a good example of a conventional time measurent using time to time-to-digital technology to reach an accuracy beyond what is possible with only very fast counters. Counters may have

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Probably what you want is the TAPR TICC - Measures the time between two 1pps,

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
David, Correct. The tinyPFA is not a conventional frequency counter that measures from a start event to a stop event and counts the number of pulses. The tinyPFA measures the phase difference between

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Hi Alex, The internal clock is not the issue as any impact of the internal clock is totally eliminated by the method used. The nanoVNA-H4 uses a well balance system design where a number of design

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Hi, Erik, Thanks a lot for this new instrument, very cool to have such gear in a homelab! Very impressive! How do You think, what else could be done to further enhance the noise floor of the NanoPFM?

Re: Very accurate phase and frequency measurement using the nanoVNA-H4 HW
Just to clarify, I take it that it would not be possible to measure the offset and jitter between two 1 pps signals with the nanoPFA? Even if the levels were reduced to the -10/15/20 dBm level? The
