Selftest fail #bug_report

 

My TinySa Ultra+, just bought on Amazon from
Pinsaitec, fails on selftest #8. I have implemented newest firmware, have done several calibration runs! No efford! What can I do, before returning the device to vendor??
Best regards, Hartmut
 

This does not look good and can not be repaired by different FW or other user action

You did not buy from an authorized vendor so you might have received a clone.
 

Sorry, it really isn't a clone. This is due to a deviation in the IF filter, and although we have rechecked it several times during the production process, there are still some with smaller deviations that passed the test during production, but could not pass the test in subsequent tests. You can try contacting your supplier for a replacement.

Hugen,

your comment is interesting for me, because the test fail #8 did not occur in every test run. Sometimes there are 4 or 5 good runs , but the next fails. Sometimes there a 3 or 4 bad runs that fail in sequence.? Therefore I ran several level calibrations, but they did not fix it.?


I will return it to vendor!

Hartmut?

Erik,

Maybe you want to lower the tolerance for this self test item.
