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

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

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: NanoVNA firmvare, compiled by DiSlord
#firmware
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 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

Re: OT: looking for testers for a tiny handheld spectrum alayzer
Hi Eric,
I will be closely monitoring the progress of this project as I am very
limited on space for all things RF as I live in a 40 foot travel trailer
and travel frequently.
My radio station/lab is limited to an area about 2 ft deep by 3 ft long,
so not much space for everything.
I am active on 1.8-440 Mhz. And I am starting to work on a 1.2 Ghz
transverter. I would be interesting in adding a Spectrum analyzer to the
kit.
Let me know how I can help.
Thanks and 73,
James Hickox, AA5AO

I would be interested in being a tester for your product, as I have 2 project antennae in the works now, and plan on another in the near future.

Rudi,
Please be aware that the H4 has more flash memory space and a faster processor
than the -H. Some features that were introduced for the H4 by DiSlord such as
201 pts and 7 configuration slots can not fit in the -H limited flash memory
space.
That was one of the prime motivations for me upgrading to the H-4 besides it 4
" display. The H4 is more future proof and I foresee more innovative features
for it in the future. DiSlord is already considering implementing support for
the optional sandisk capability of the -H4 for saving screen shots and trace

Hello Herb, In posting 12801 in that thread DiSloard publishes an address of google drive. In that archive I found file NanoVNA-H_v0.8.4.3_96kHz_ADC_800Hz_sweep_points.dfu (83 KB) That works on a 8 month old nanoVNA. 73, Rudi DL5FA

Re: OT: looking for testers for a tiny handheld spectrum alayzer
Erik,
I might be interested in playing with one of those.? I don't have a project so much as I do have friends who are excited to learn about electronics.? I showed one how AM and FM spectra are different and how they change with modulation depth and frequency.? It was interesting to see his take on what goes on, that the books were really right about all of it, including Bessel nulls and all.? Another aspect is to see how the old signal generators have incidental FM which not only spoils the modulation quality but also offers an unintended FM generator.
Seeing how harmonics change depth with signal amplitude is also interesting, as the panel controls and manuals give no clue.? And again, the old generators have gratuitous distortion.
Audio generators are not free of these complications either.
I have a few spectrum analyzers which could serve as comparison vis amplitude and frequency calibrations.
So if I can be of help let me know.? I am in Los Angeles California.

Hi Hugen!
That was a very simple solution. I loosened the screws up and the device started working. Then I tightened them just enough for the case to close and all is working fine now.
Thanks a lot!! I was afraid to have to send the device back and wait another 6 weeks.

After waiting for 6 weeks I received my NanoNVA-H4 today. Very nice device, even nicer packaging.
When I started the Nano the right-hand menu showed up and was stuck at the RECALL option. I was not able to select any other option. Whenever I tap the screen I get back to the RECALL option. Sometimes is cycles between RECALL 4 and the RECALL sub menu.
I think something is stuck in the touch screen, however, I cannot see any physical damage.I upgraded to the latest version on which was supposed to fix the stuck screen, but this doesn¡¯t help.
Do you think my screen is broken?
Thanks,
Ton.
