TinySA Ultra+ ZS406 Self test Test 8: Passband failed ? #bug_report #ultra
|
Hi guys, I got the? TinySA Ultra+ ZS406 today from Eleshop. I updated the firmware to tinySA4_v1.4-198-g996a67b.bin (Picture 1). ? Before that, I had a Firmware from January 2025. ? I did the Self test two times, which failed on Test 8 Passband failed (Picture 2 and 3). ? Then I did the Level CAL" 100kHz to 5,42GHz" and then I tried the Self test again same problem with Test 8 Passband failed. ? Then I Reset Calibration and did and did the Level CAL "100kHz to 5,42GHz" again. ? And then the Self test again and now all Test passed two times again. ( picture 4 ) ? ? And the third time it failed again Test 8: Passband failed again, everything else passed ( picture 5 ) ? ? And the fourth and fifth time Self test all passed again. ? Then i did the Level CAL "100kHz to 5,42GHz" again and Self Test again Test 8: Passband failed again ( Picture 6 ) ? ? The next two Self test all Test passed again. ? The third Self test on Test 8 Passband failed again ( Picture 7 ) ? ? Should I return it to Eleshop and get a new one ? Are the Values of of Test 8 off by so much or just minimally off ? |

Hi Hasan,
that is exactly the same selftest behaviour than with me! I have sent my Tinysa back to vendor, but I wonder it might be a systematic error. Perhaps the tolerances of test#8 are a bit tight? And Eric, what could be the consequences of a spurious fail of test#8? What does this test really messure? Hartmut Von meinem iPhone gesendet |
