Re: New ULTRA FW release: Bug solved: UI for ultra correction table not working
Wow Erik, in germany we say, you are faster than the police allows ;-)
I'm wobbeling the tinysa after the calibration at the moment. I'm at 2GHz at the moment. If it is finished, I try the new version.

Re: New ULTRA FW release: SD card file names and hangup fix
Is there a place where I can find a change log, rather than looking through the messages? Basically, this with the dates? The only change log I found on the wiki was for the wiki itself.

As stated in the wiki the tinySA can only do AM detection, to hear FM stations you need to use "slope" detection. This is what I do to listen to the FM broadcast band. Attach telescopic antenna Plug in sensitive headphone Set start to 85MHz Set stop to 105MHz Enable LNA See all the FM stations appear  ?Set RBW to 100kHz Enable LEVEL/LISTEN Grab the marker and move on the side of the FM signal (as shown above) Now you may hear the FM station For sure you will hear noise --

Re: Unable to get Listen to work on Ultra
Sam,
The Listen function works only for AM modulation signals not for FM.

Also I noticed that often the sweep stops when I check the listen box but restarting the sweep makes no difference. I can set the span to 0 and see the audio so I know that is working with plenty of amplitude.
This is a brand new unit I bought directly from the official store so I know it in not a clone. I received it a few days ago,
Thanks for you help.

Re: New FW release: Add SAVE STATE and LOAD DEFAULTS to PRESET menu
Thank you Erik for the quick response. I understand that it is related to the 10 Kcycles of the flash memory endurance.

Re: TinySA Ultra and TinySA App
The disconnect problem seems to be fixed with installation of the latest firmware...thanks Erik! --

New ULTRA FW release
Version V1.3555
Changes:
- Bug fixed: after some time the tinySA Ultra hangs when scanning using the tinySA-App
- Added menu STORAGE
- Added option STORAGE/AUTO NAME to enable manual naming of files
- Added STORAGE/LOAD CMD function to load and execute commands from sd card
- Added STORAGE/LOAD BMO function to browse capture screens from sd card
- Added CONFIG/MORE/EXPERT CONFIG/HARMONIC which makes it possible to set harmonic to 5 allowing the Ultra to reach 20.7GHz. All level calibration above 800MHz will be invalid after changing harmonic
- Added option PRESET/SAVE STATE, when disabled the tinySA will always start with the range set in the STARTUP preset and not load the last used range.
- Bug fixed: In clean output mode it is possible to set output frequencies above 4.4GHz
Erik, ? Using firmware Version V1.3555, I ran tinySA-App in continuous scan mode for over an hour under various operating conditions (switching focus to another application and back, going to screen saver mode, performing screen shots) and could not induce a timeout fault.? Hopefully you have put that issue to rest.? Maybe someone who is using tinySA Ultra to continuously record a portion of the frequency spectrum to disk can test more thoroughly. ? The additional SanDisk file operations in the new firmware are a welcome addition, as are the new command files. Maybe you or DiSlord can provide some example cmd files for setting various color schemes on the tinySA Ultra.? The current $119 selling price of the tinySA Ultra is tremendous value and your technical support makes it even more so.? Any electronics enthusiast would be happy to find the tinySA Ultra in their Christmas stocking. Herb

Re: New ULTRA FW release: SD card file names and hangup fix
Erik ? I have the new release ?tinySA4_v1.3-555-g359ccc1 running with connection to TinySA App on continuous scan for over an hour without any problem. The occasional change in the VNA comms trace where the new entry doesn’t feed in at the base of the window (as the screen scrolls up), but the window is largely clear and the entry line is toward the top of the window, ?is now occurring very rarely. So rarely that I have only seen it occur twice, whereas before it seemed to be every 4 or 5 minutes ? A very good result ? Thanks ? Mike G8EII . ? ?

Re: #ultra Bug in the correction

That is on purpose
You can only update the level using a known test signal using the UI
Use the usb commands to change the frequencies? --

#ultra Bug in the correction
#ultra
In the correction for the ultra mode is a bug. It's not possible to correct the level for a frequency in the tinysa itself. If I click on a frequency entry, nothing happens. In the normal mode it works. The only way to correct the levels is to do it in the command line.

It would be nice if you can test the latest FW with HARMONIC set to 5 above 6GHz Maybe measure the reported level of a -10dBm or 0dBm input signal every 0.5GHz up to the maximum input frequency (20.7Ghz) Make sure you set the attenuation to manual 0dBm as the attenuator induce a big measurement error above 6GHz. This will give prospective users an idea what sensitivity (if any) to expect --

Re: Invitation: How high will your tinySA Ultra go?
Hi,
if there is any need, I can do tests up to 40GHz with a Anritsu 37369A VNA, a Anritsu 40GHz source and IFR power meter up to 46GHz.
The equipment isn't officialy calibrated but I know how my tools run ans can be accurate to 1dB up to 2GHz and to 2dB up to 40GHz.
So please tell me if I can do some measurements that help you.
All the Best,
Isidro

Hi Herb, MirekD and others
It is correct I have the facilities to create correction tables beyond 6GHz actually to 18GHz. I am presently working on all the correction tables now the TinySA ULTRA is produced on pick and place machines and not hand soldered as the prototypes was, which has improved some characteristics.
I think it just is a matter of the ULTRA receive correction table and it takes just a split second to swap the original correction table specific for ULTRA (after a prior backup) with a new Ultra trial correction table.
It is simply done in the terminal command screen of a terminal emulator program like KiTTY and first read the embedded Ultra correction table (and copy paste it to a text editor as a backup) and then copy paste the new experimental Ultra correction table delivered as a *-txt file
Kind regards
Kurt ?

My guess is that ham operators and electronic enthusiasts will see the potential in the tinySA Ultra and articles will start appearing that extend the capability of the tinySA Ultra to 12GHz and above.? The software is an area where a guru could definitely fill a void and build a multi-platform application, such as nanoVNA-Saver, for the tinySA Ultra. Erik has done a fine job modifying Cathy's nanoVNA-App program for the tinySA, but his real expertise is hardware and firmware.? That is the main reason tinySA-App is not as robust as the hardware.

Erik,
I am bound by a strict NDA on why, when, and how the units WILL fly.
As the project progresses, I will certainly update you if you wish.?
My registration has my email, please reach out that way.
Now that I know serial communications are an option, three units will go? ...3, 2, 1 ignition!
If the vehicle team allows it, there will also be a video.
Now, for the tricky part... find four or five TinySA Ultras, for it is out of stock everywhere.
If you have the answer to that one, I will put my supply chain folks on the task.
Thank you for replying... much appreciated.

Wolfgang, ? ?Erik has provided a Python library at:???.?? The long running scripts I mentioned were written by Erik during beta testing to characterize the operation of the tinySA Ultra.?

The tinySA Ultra can also be controlled from NanoVNA-APP v1.1.209 and I received a serial timeout within an hour of run-time.
