Re: #ultra Bug in the correction
#ultra
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 --

New ULTRA FW release: SD card file names and hangup fix
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 Although some users have demonstrated that it is possible to see signals close to 18GHz, the measured levels will be completely wrong and there is little dynamic range. --

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

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.? Erik may selectively release some of the more useful scripts in the future. ? 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. So, the timeout issue was already present before Erik modified the application for the tinySA.??  Herb

Re: Invitation: How high will your tinySA Ultra go?
That would be great, gives us a change to explore SHF more.
We have local beacons on 13, 9, 6, 3,? and 1,5 cm? ( 6mm 47 GHz is planned).
Also the local GSM mast has a 39 GHz link according to antenneregister.nl

I don't understand the problem of using dfu-util (or dfu-util.exe on Windows). Just type: "dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D tinySA_vx.y.z-nnn.bin"It works out of the box on Linux (even on a Raspi), MacOS, FreeBSD (as well as other BSDs). The only thing a Windows user has to do is to execute Zadig just one time as a setup. So it is a real "platform independent" solution. Martin

Re: Invitation: How high will your tinySA Ultra go?
That sounds interesting.....
Does it mean that it is more difficult to clone the Ultra? .... Excellent.

Re: TinySA Ultra and TinySA App
The TinySA app, with repeated scan off, makes a routine call to the TinySA for information (every 4 or 5 seconds) this includes the vbat data. I ran this for over one hour without any sign of failure. So I think the fault is not just vbat, but depends on other circumstances, maybe when the TinySA is very busy scanning and servicing comms there is an occasional glitch around the time of servicing the vbat routine ?

I can move the command to unlock above 12GHz to the expert config menu Internals menu will remain locked as it has many ways to kill the tinySA performance. --

Herb, unfortunately it's related to the firmware of the tinySA & Ultra. The vbat command of the tinySA sometimes times out and therefore tinySA-App hangs. Please let us know, what Python script you are usings and a link to try. 73's de OE1MWW Wolfgang

Erik, wouldn't it be useful to be able to do FW updates/reloads from MicroSD? It would be platform independent, as long as you can write to the card, you can do updates.
