Hello to all, I am trying to load the updated firmware to the tinySA, but when I go to put th3 file in the DFU File Manager, set the tinySA to DFU mode,I cannot see the tinySA in the Available DFU Devices, and it will not install. I am wondering if I need to install a Driver for this tinySA,or what to do,i am running Windows 10. Any help or let me know what I need to do will be Appreciated. I want to thank al who may help me out. Have a great day,,also, this little thing is totally amazing, as I set my Signal Generator to the side, and use this SA when I am aligning CB radios, it works pretty well, need to get a power pack for this for when I go to work on the antenna this spring,as the batteries do hold up pretty well, as it is to hold for about 2 hours. Thanks again,,Mark,,

mine broke 1hr after getting my vna but rather than changing the switch i think i will go with a much simpler solution (for me) and just replace with 3 regular miniature push button switches and in my opinion these jog switches are way too easy to break again.

Thank you Erik!

Sorry, but this is an illegal clone. No doubt.
A very nice visual copy, but not at the right performance.

Seems authentic.

Robert,
I'm not sure this is a genuine tinySA
Can you post photos of the sticker on the back and the PCB?

Look at eBay item 121096249091. SLLB310400 ALPS. I bought two when I needed one.

Hi,

I received a second tinySA today.? Now I know why I have been having so much trouble navigating menus on the first unit, the spring (or something) is messed up in the jog switch.? The new unit I just received fails two self-tests but the jog switch is nice and firm and positive in its action when pressed or jogged.? I guess I got used to the switch going bad on my first unit.? Anyway, could a manufacturer part number, link or such information be provided so I can get a replacement for this switch?

Thanks and 73,

I've just updated the firmware with 1.1-77 and my unit with the S/N: SA-20080475 works fine. The self test and the linearity test are all OK.

Happy days!

One other thing.? The new (problem) unit seems "dirty" when the low and high inputs are connected together (no cal signal turned on).? My original has just two little spurs while this one has a bunch.? Sorry for the barrage of posts.? Hope the info will help to get to the bottom of the issue.

A data point.? I happened to notice that the Reference Level (set to auto) is going to +10 on the new (problem) unit and to 0 on the properly working unit.? Could this be a clue?

Please disregard the version screen that somehow got attached to my posting.? I had something odd going on with upgrades and both units were showing version V1.1-59 even though I was using V1.1-77 for the upgrade.? I redownloaded the file and made sure to use that one and both my units are now at V1.1-77 as indicated by the version screen.? Thanks.

Hi,

I just received a second tinySA and it is failing two self-tests.? It appears to be an authentic unit.

I upgraded to V1.1-77 on both of my units.

I performed the Level Calibration and then executed Self Test.? Here are the errors:

Test 5 Above Critical



Test 7 Stopband Fail



Otherwise, ST is okay.



Did attenuator test and that seems okay.



Thank you,

Robert, WA2T

Thank you everyone. It was indeed staring me in the face!!!!!!!!!

Open the Comms window (small button with USB connection symbol)
Connect tinySA and switch to high mode using tinySA-App
You should see in the log

and no error messages

I have. Bit of a loss with this at present.

This is not a problem, The fail threshold is -75dBm and you measure -74.6dBm. I guess I may have made the test just a bit too tight.

Very good service from R&L to resolve this.
