Hi Erik, I will test the new FW update later today. BTW thanks for the nice job you did with this project and your quick response for every one that had some questions. 73, Wim.

I came here after being recommended to join the group in the QRPLabs groups as I was looking at getting a TinySA Looking at the information about how to spot a fake, mainly by serial number I

Hi Larry. I bought my tinySA in the first shipment available from Zeenko (they had maybe 100 units available). I asked in another post about the graph, just to be able to compare the result with other

Hello Erik, Thank you for developing the tinySA. You keep telling people where to buy an original. ?How the hell do some keep getting clones. ?Are the recommended dealers somehow receiving clones

Can you try if the new release solves the problems? -- ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

New FW release Version V1.3317 Changes: - Bug solved: Setting the actual input level gives wrong leveloffset - Bug solved: Green line remains after

Try a different charger. I had some of the cheaper chargers stop working after a few month the cheap capacitors used wear out because they are marginal to start with. I actually build a small linear

Erik. This is the result for my tinySA (first release). Is this the expected graphic for an original equipment?

Thanks, this confirms its a clone You will have, even after careful calibration at the target frequency, up to 5dB measurement error ------------------------------------------ For more info on the

Attaching the picture as suggested by you:

Thanks Erik for your quick response. Now my doubts are cleared. I will do the same as recommended by you. Due to not so friendly relationships with India and China recently, getting the original

Its an illegal clone, for sure. The passing of the self test does not ensure if you will have accurate harmonics measurements when the tinySA has been made with wrong components as shown at the end of

Try using a new USB-C cable, see if that helps. I've had loads of problems with the USB C cables wearing out quite quickly. The cable may not be the cause of your particular problem but it certainly

Hi Erik, First let me thank you for creating this lovely equipment, looking at the size and functionality of this test equipment few years back it would had been science fiction :-) Coming back to

I have a genuine TinySA purchased from the Zeenko store on AliExpress. it worked fine when i go it, battery charged up OK, over 4 volts. Now it will only charge to 3.27v and the red charging LED goes

I also noticed this error, even the error is in the adjustment of the LOW input and the HIGH input, but if you inform the calibration level exactly circa times, it will accept the correction in the

Thanks, maybe something went wrong with the latest FW update. Let me check. -- ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

Hi Erik, The high input calibration is done with a nanovna as hf generator at 250 MHz (CW) the output signal measured with the calibrated low input of the tinySA, that worked well and the self test

Wim, How did you perform the high input, or did you calibrate the hi output? -- ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

Hi Erik, installed the latest firmware update yesterday. when re calibrating the "hi-input" it turned out that this did not yield the desired result instead of e.g. -34.2 dBm I came to about -10 dBm
