Re: NanoVNA firmvare, compiled by DiSlord
#firmware
i don`t understand
1 variant is last firmware
2 variant - is 0.8.4.3 (Only 8kHz IF change)
3 variant - is old 0.8.4.4 (2x external freq)
You not fogot reset self NanoVNA calibration before calibrate in NanoVNA Saver?
Try restore last worked firmware

DiSlord,
Flashed number 2,? threshold set to 300MHz,? recalibrated NanoVNA-Saver,? S21 at 0 now,? R+jX? R still not shown, S11 49.85 Ohms standard? way off , Marker 1 an 3 not shown. See pictures.

Check this 3 variants (all of them work good on my H4, try set threshold to 300MHz)
Need recalibrate

DiS;lord,
Flashed number 1, recalibrated in NanoVNA-Saver, still no good, see picture

What is the approximate cost of the device?

Please not use old calibration, recalibrate after update

In version v0.8.4.4, the level of CH1 rises after 300 MHz.

Hi DiSlord,
Loaded your latest version of00000000000000 firmware 0.8.4.4 into my NanoVNA H4 and calibrated in NanoVNA-Saver. Results are not as good as in previous firmware see the pictures attached, sorry.
Measuring my 49.85 Ohms standard as 54.xx Ohms , ? when I measure CH1, R? is not shown in R+jX and S21 is not 0. .
See also my pictures taken with the previous firmware I had sent.
Regards
Jos

In 0.8.4.4 i only change IF to 8kHz
Other changes only for H4 (H version can`t fast process DSP in 64bit integer, H4 have hardware support for it)
PS change 96kHz mode for AIC ADC i will revert (this mode have more noise), i found PLL set error in AIC init, and now i test fix

Hello DiSlord,
Yes, you did up to version 0.8.4.3.
Unfortunately the version 0.8.4.4 for the -H (not -H4) version is missing.
I am very happy with your version, especially for audio measurement (from 1
KHz upwards).
Please have a look at the appended screen shot
WSPR_Cauerfilter_LP5_3KHz_nanoVNA.png
It shows an audio Low-Pass filter measurement with a cut off frequency of 3
KHz.

Re: OT: looking for testers for a tiny handheld spectrum alayzer
Erik
I would like to be a beta tester. I have a RIGOL DSA1030 Spectrum Analyzer that goes from 9 KHz to 3000 MHz, a sweep generator that goes from 1 MHz to 1500 MHz, a RIGOL DS1202Z-E Digital Storage Oscilloscope that is 200 MHz dual trace with the software package to analyze various serial comm standards, and a Motorola R2200 Service Monitor that goes up to 1000 MHz. If you have any questions please contact me.

Re: NanoVNA firmvare, compiled by DiSlord
#firmware
Long read TLV320AIC3204 datasheet (unfortunately it is poorly written)
Revert external freq set 96kHz mode for AIC ADC (this mode have more noise), use internal multiplier as before (i found PLL set error in AIC init, and hope fix it)
Not use fractional multiplier for AIC PLL clock (look like less noise)
Add delay for SI5351 PLL reset (more stable on band change)
Some code optimization and definition fore easy control build
PS in CH1 mode noise level drop ~3-5dB
PSS i hope now not need change threshold

Re: OT: looking for testers for a tiny handheld spectrum alayzer
Hello Erik,
I would like to test your spectrum analyzer. I have used an old HP 8558B to illustrate USB and LSB. However, the resolution just barely illustrates this and I have been looking for a better SA. I also use it to show the difference between broadcast FM, our FM on two meters, and commercial narrow band FM. I also occasionally us a SA to troubleshoot amateur equipment. Below is a photo of some of my equipment.
I have also ordered a nanoVNA-V2 and am waiting like everyone else for its arrival. I have used a miniVNA for years to evaluate antennas for myself and club members. I¡¯m looking forward to a new device and being able to check antennas up to 1296.
I will be following the development of your SA.
Thanks,
Joe

During the last weeks I have been designing, together with Hugen, of a self contained, ready build, hand-held spectrum analyzer to be sold for a very acceptable price.
The outline and display are exactly the same as the nanoVNA and the tinySA will come with a housing.
As the HW performance now seems to be OK and the SW is more or less complete i could use the help of some (not many) testers.
Preferably people that already own (or have access to) a spectrum analyzer and are active building something that requires a spectrum analyzer in the 0.1MHz till 350MHz range.
This tinySA can also capture 240MHz till 960MHz (with somewhat reduced performance and functionality) and it can also be used as a signal generator (0-350MHz and 240MHz till 9060MHz)
If you think you could contribute to the testing feel free to send me a PM with some info on the project you'd like the tinySA for.
There will only be a limited number of tester products.
Selected testers will receive a tinySA and are kindly requested to use it and feedback their experience.
I create a dedicated tinysa group for this purpose. /g/tinysa/topics
More information on this version of the tinySA can be found in this wiki
Please be patient as the wiki is running a bit behind.

I had the same problem.? The H4 would not start but 1 time in 10.? and froze under computer control.
I put small nylon washers on the mounting screws as spacers to keep the case from touching the screen.
Also had to file out the hole for the USB-C cable.
Works great now.

It looks like your NanoVNA-H4 that we sold earlier has a distorted case,
you may need to loosen the screws on the back to start properly, we have
fixed this issue, you can contact us for a new case. Sorry again for our
mistake.

Re: OT: looking for testers for a tiny handheld spectrum alayzer
While I do have some test equipment and enjoy working on antenna I would love to get a hold of one of the units to connect it to a PC for a larger screen like NanoVNA-saver does for the NanoVNA.

Re: OT: looking for testers for a tiny handheld spectrum alayzer
Erik,
I have a pretty good set of test equipment and would be happy to test the tiny SA for you. Am particularly interested in the minimum bandwidth as someone else here mentioned to look at modulation sidebands,

Re: OT: looking for testers for a tiny handheld spectrum alayzer
Erik:
I had suggested the possibility of such an item (SA with tracking gen)
quite some time ago.
And, while I'd be very happy to be a "tester", I imagine there are many
others who would be better qualified than me.
In any event, I plan on following your development of this item.
Sincerely,
Paul
