Re: New tinySA failing Self-test after FW upgrade

It seems your attenuator is bad.Erik, ? To take the drudgery out of manually entering 31 attenuator values, would it be possible to either add a module to TinySA-App (Settings?) that performs an extended attenuator test, as outlined by yourself above, or write a separate executable that performs an extended attenuator test?? An extended attenuator test would also help hugen to detect a device with a borderline bad attenuator in the QA process before shipping it. ? Does the manufacturer? specify the number of operations the attenuator can be switched (MTBF?) before it needs to be replaced? ? I can throw something together for myself in C#, but my programming skills are not good enough that I would trust publicly releasing an executable. - Herb |

Re: What to do when you think you bought a tinySA clone.

Well, we have already established it is a fraudulent, and by the way illegal, fake. The customer service representative is asking for more and more info, while it is already clear that this is a fake item. (I don’t care whether it works, which it doesn’t properly:? it’s a counterfeit item, and I bought the real tinySA.) For your amusement (Schadenfreude? :-), an internal photo of the fake is attached (I only took the plastic cover off, no other changes by me). Grü?e, Carsten |

What to do when a selftest fails
If one or more of the self test of the tinySA fails AND you did NOT buy from one of the safe sellers (see wiki) you can do the following:
If the Attenuator test (test 12 in the latest FW) fails follow this guide in the wiki:? If the serial number at the back of your tinySA starts with "AD" you have a clone. Complain and get a refund. If the text next to the high input connector is "HICH" you have a clone. Complain and get a refund. For other failures make a photo of the front and back of the tinySA and a photo or screen capture of the failing self test such that it is possible to read the text on the screen and post a message with the pictures. ------------------------------------------

I seem to be getting intermittent Test 3 errors as well.This could also be caused by an attenuator problem but it is not a big problem, just on the edge ? -- ------------------------------------------

Hopefully this is helpful.It seems your attenuator is bad. You can verify this by enabling the cal output at 30MHz (MODE/Cal Output/30MHz) and putting the tinySA in low input mode with center 30MHz and span 10MHz.? Set LEVEL/ATTENUATE/MANUAL 0 (0 dB attenuation) and write down the level of the 30MHz signal Then increase the attenuation in 1dB steps and see how the noise floor moves up and the level of the 30MHz signal stays the same. If the 30MHz signal level suddenly makes a jump up or down when changing the attenuation write down the attenuation levels before and after the jump and post your observation. If the attenuator is bad you can contact your seller and the issue will be resolved ? -- ------------------------------------------

Selftest errors
I just received my TinySA on friday. So after watching videos on how to use it, I ran the selftest and I have a couple of errors. Test 10 gives me a signal level critical error and test 11 give me an attenuator error. I purchased it from R and L in the states so I'm sure a received a good one. Is there anything I can do to fix these issues or should I contact R and L about a replacement for the defective unit?
Thanks, Hal |
Re: New FW release: Corrected hang after display test fail
I just installed the new firmware and when running the self test on test 10 I'm getting Signal level Critical? for the status. Then on test 12 I'm getting Attenuator Fail for the status. I just received my TinySA on Friday so this is all new to me.
Thanks, Hal |
