In addition to the packages mentioned below, it is also necessary to install opt-python38-setuptools from the OpenSuSE site. Then pip can do its magic. Gary AG7TH

Agree, also have problems with CHibiOS compiling in STM32CubeIDE 1.3.1

You forgot update git submodules

And my H4 calibrated with stock coaxes and loads, and with 0db -3db and -23db (3+20) attenuators. FW - ~latest github source.

Hello, Went through all the steps to get Chibios Eclipse and Github, then cloned the source. It does A LOT when compiling but quits here: Makefile:90: ../../../os/hal/ports/SPC5/SPC563Mxx/platform.mk:

This freshly calibrated (OSL) with stock coax and load. Latest fw from github. Your little VNA-H looks good, imho..

Yes, you can install more than one OS - just re-partition your drive or install on different drives if you can. GRUB will be updated accordingly.

To get an impression of the usability it is useful to look at the phase of an open S11 i.s.o the magnitude of the noise Often at higher frequencies the magnitude is determined by various harmonic

Can I have both Ubuntu and OpenSuSE installed on the hardware ? ( I do not want to "update " Ubuntu ) It should work as "dual boot ", right? I was trying python for last two weeks and the "latest"

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
