Re: Banggood, is tinysa.org updated?

 

To my knowledge there are today (May 12, 2025) no clones of the Ultra+ models.

Re: Banggood, is tinysa.org updated?

 

¿ªÔÆÌåÓý

Hi, I think I'll chime in with my Banggood experience. I did not know about this group when I bought it, or the concerns about copies and clones were so bad.?

It also did not come with a stylus.

I don't have any complaints about it, it works good.

I did ask the seller beforehand, if it was authentic, and capable of being upgraded, because I saw their policy said "flashing firmware voids your warranty."? I did do /some/ research first.

It is the ZS-406 model, and it can measure up to 12.072 GHz after unlocking Ultra mode. Barely into the range I really want to measure (Starlink). I guess they were liquidating their older inventory, thus the sale price.

Now I wonder if ZS-407 can go higher, since the base frequency range is up to 7.3 instead of 5.4, I wonder how that corresponds to the Ultra range expansion, and how that compares to authentic hardware. Which is newer? Can the cloners make more capable hardware than the authentic version?

Thanks, Stewart

This is how looks tinysa ultra + from banggood. I dont have any calibrated signal generator to test how to measures. Seller says its genuine, i dont think so, there was no pen stylus inside.

Very interesting. Please let me know which settings have you used, as I have a similar problem in 6m band. It's a wide-band QRM. It's impulsive and is also present as well.

Re: Level Cal -> signal level incorrect (only sometimes)

 

Hi Erik, understood, many thanks for your fast answer and have a nice Sunday.

Re: Level Cal -> signal level incorrect (only sometimes)

 

Judging from the picture the signal level is just on the edge of a rather arbitrary boundary condition I've defined.
You can safely ignore this.
Will adjust the value in a future FW release.

Level Cal -> signal level incorrect (only sometimes)

 

Hi there!
?
I recently bought an ZS-407 (HW 0.5.4, FW -197) from Eleshop and just wanted to ask if it is a non-issue when the Self-Test is fine, but the "Level Cal"
says "Signal Level Incorrect" (-> but only sometimes).
It does that like 1 in 7 Cals. It does not seem to matter which cable(s) I use.
?
Example see picture please
?
And many thanks in advance for some insight :)
Regards, Seb.

Re: Auto Save Issues

 

If it's any help, QtTinySA can save trace data continuously to a PC (including Pi) and does it as fast as the tinySA can scan.

The Wiki describes how it works:

Re: clone or not?

 

Michael,

Strange behavior.
Normally, the switch on the left is on the OFF position and the switch on the right is on the ON position. Regardless of whether the USB is plugged into a computer or 5V DC source or not plugged.
Re: Auto Save Issues

 

Thanks you for you're reply,

you confirm me the Tiny SA Ultra+ can't record the integrality of the realtime signal on his sdcard, and need external recorder ?

What sort of model of rasberry pi is correct to record in term of power (cpu, IO...)
if have two or three tiny sa in // the Pi can record them simultanously with your're software ?

Re: clone or not?

 

Thanks for the quick reply and I'm glad it's an original. As I plan to buy some more I had to be sure that they are not copies.
With the firmware it was stupidity on my part because I thought the programming time was displayed, but it is the build time and this does not change if the current firmware is already installed. Installing an earlier version works fine and then the build time also changes.
Another thing that drives me crazy is the power switch. When I have connected the TinySA via USB, I cannot switch on the device.
When I unplug the USB and move the switch from the right to the left position and then immediately back to the right position, the device switches on. Is this normal switch-on behaviour? Incidentally, I can also switch the device on in this way if I have connected the USB cable to a power supply unit rather than to the PC.
However, I always have to switch the switch back and forth quickly.
I've tried it umpteen times and always get the same result.
Re: clone or not?

 

Eleshop for sure does NOT sell clones.
Did the FW version number change?
If not, you may have loaded the FW in the wrong direction (into your PC) or you have a problem with a USB 3 port
Download the FW again and try again to update
If the updating takes a very long time you are probably connected to a USB 3 port. Find a cheap USB 2 hub to put in between the tinySA and the PC or a computer with USB 2 ports as USB 3 on some computers is not compatible with the FW update protocol.
If the battery level is yellow or red, selftests may fail although some measurements are still possible.

clone or not?

 

Hello,
?
I bought a TinySA from the secure seller Eleshop B.V. Nevertheless, I am not so sure that it is an original. The following points:
Switching on only works by toggling the power switch and when USB is connected it usually does not work.
Even after updating the firmware, the firmware release date shows an old date, even if the firmware is actually up to date.
Yesterday I had problems with the self tests. It could also have been due to the battery level which I unfortunately did not check and this morning after it has charged overnight the self test works again.
Yesterday self test 1 did not work at first, later 1+2 and then later 1-4 did not work.
