Yes I know, I was having problems in the early days with previous/current scans coming in and changing the scan range at the same time, so I made it stop the scan whilst your editing the scan range -

It ought to be working, not sure what might be wrong yet. This is on my little VNA-H. Not very good up at 2.7GHz but it's doing it.

v0159 does not disconnect the serial. Editing the Start/Stop fields changes the actual scanning range only after pressing Enter. The Enter stops scanning - thus you have to start the scan again by

Try the latest Igor, let me know if it's still wrong. v.0.1.59

H4 always work on 10752000U, 8MHz come from H variant on my try set code some But yes you can try all variants

I see thereis a higher AUDIO codec ref clock set now // Define aic3204 source clock frequency (on 8MHz used fractional multiplier, and possible little phase error) //#define AUDIO_CLOCK_REF (

you can try use my compiled variant (v1.0.11 better), at this moment i try find better stable settings

After entering a new frequency in Start or Stop fields and pressing the Enter it disconnects from the H4.

OK, I messed something up before, I've done the build again and it runs now on H4 here (commit 0.7.1-154-g8e95645). It freezes when in the "Version" screen after couple of minutes here, however.

The maximum that the software will do is just over 4.1GHz (unsigned 2^32), not sure what's going wrong for you. Can you maybe show me the comms window output, see what it's actually sending to the VNA

For what it's worth, SMA connectors are as good as N for the most part, until you get into fancy N or 3.5mm connectors. Are you "gauging" your connectors before measuring? Using a torque wrench?

I upload only 192k support, now need find better settings (not upload part of them, you can select variable table support and try 12,24,28k offset settings). At this moment 24 and 28k IF frequency

Hello David, SAA-2N still uses the original SAA-2 PCB without any changes.

Hello Mike, the cost of using DHL to send to the US is about $25.

Hello OneOfEleven, we are evaluating whether our supplier can provide SMA connectors comparable to Amphenol. If possible, we will use better connectors in next-generation products.

Hello Rich, using DHL, you are expected to receive it before the end of August.

Dear Dr. David Kirkby, Hello, our products have been commercialized and we attach great importance to compliance. We have sorted out all licenses that may be involved in NanoVNA and SAA2. NanoVNA

Hi Igor, Did that too, enabled RTC, SDCARD, enabled 192K and it works ok for me. Also, in order to have the same IF as with 96K I've modified the nanovna.h at line 50 with this //#define

I've built from latest sources with RTC/SDCARD and 192k ADC but H4 does not start..
