I got mine yesterday from Zeenko.? Followed Kurt's video to install the latest FW and set the Ultra Code. I'm having the same (or similar) issues.? The touch screen makes no sense.? I can touch one

Many thanks, Erik!

John, You can also measure the attenuation without the math by first normalizing the CAL output signal as below: CALOUT: [email protected] TRACE1->NORMALIZE 20dB Attenuator between CAL OUT and RF IN.

Will be in next release -- For more info on the tinySA go to https://tinysa.org/wiki/

Is there no merit to my suggestion to remove the slash from the 0 digits? The slash makes it difficult to distinguish between 0 and 8. A slash (or a dot within the 0) is normally used only to help

Hi John When I just ordered the tinysa ultra from the official Store Zeenko store on AliExpress It did not say anything about backorder, Thanks Dave wrote:

Oh how true, I was very happy with my HP3400A. until I got a second one. There were some frequencies with a 16% discrepancy. Mikek

I would not be surprised, Seeing that the official stores have them on back order but e-bay and Ali express have several vendors selling them. Every day more vendors from China pop up on e-bay.

Thanks Erik I have ordered a tinySA Ultra From?Zeenko store on AliExpress Seeing this is the factory store I know all will be good, Thanks again for your help Erik Thanks Dave 2E0DMB

I never would have thought of using the CAL function in this manner - works like a charm: https://ae5x.blogspot.com/2022/12/using-tinysa-to-measure-attenuation.html -- John AE5X

Hi ,has the tinySA Ultra been cloned, am I safe getting it from AliExpress, Thanks Dave 2E0DMB

Yes, you have a clone. Next to the serial number, the screen capture from self test 7 tells me its a clone. I can not help you with performance or measurement problems. -- For more info on the tinySA

Ok Erik Thanks I will get the new model ultra when I have some cash, Thanks for your help Thanks Dave

Hi i have just been reading the tinysa info page, ad it says that if the s/n starts with AD it is a clone , is this correct ? my S/n is AD01210501246, Do i have a clone , i have done the other tests

You have a clone, can't help you. -- For more info on the tinySA go to https://tinysa.org/wiki/

Test 7 flatness fail

i am using a HP radio test set to measure the output from the tinysa Thanks Dave

Hi Erik, if i set the tinysa to output -10dbm at say 100mhz the real output is only -17.5 -18dbm so the output gain is a lot lower then it should be , do i have a bad amp stage in the tinysa, this

Can you share a screen capture or photo of test 7 failing. The fail is due to overly strict criteria as we are only now collecting statistical data on the correct boundaries for test 7 Do you mean
