continuing from thr = 0.99V again
  178   Thu Jul 3 09:10:55 2025 tb-crew thr scan W8-2 1E15Topside4.20.99-400 Good   
no proper beam atm
  192   Thu Jul 3 14:46:26 2025 tb-crew thr scan W3-8 5E15Topside4.20.95-50 Good   
changed DUT
  194   Thu Jul 3 14:57:35 2025 tb-crewbias scan W3-8 5E15Topside4.20.95-25 Good   
chip seems noisy, no good Correlations
  196   Thu Jul 3 14:59:49 2025 tb-crewbias scan W3-8 5E15Topside4.20.95-25 Good   
changed thr to reduce noise
  198   Thu Jul 3 15:03:03 2025 tb-crewbias scan W3-8 5E15Topside4.20.96-25 Good   
changed scan time to 5 min
  203   Thu Jul 3 15:29:45 2025 tb-crewbias scan W3-8 5E15Topside4.20.96-200 Good   
increased compliance to 200uA
  205   Thu Jul 3 15:32:40 2025 tb-crewbias scan W3-8 5E15Topside4.20.96-400 Good   
restart from -200V
  211   Thu Jul 3 15:58:34 2025 tb-crewbias scan W3-8 5E15Topside4.20.96-400 Good   
hit compliance at 400V
  214   Thu Jul 3 16:11:34 2025 tb-crewbias scan W3-8 5E15Topside4.20.96-350 Good   
can't set compliance to values > 200uA via producer, trying manually now
  218   Thu Jul 3 16:34:56 2025 tb-crewbias scan W3-8 5E15Topside4.21.1-400 Good   
increased threshold
  229   Thu Jul 3 17:44:29 2025 tb-crewbias scan W3-8 5E15Topside4.21.09-400 Good   
rerun bias scan with increased thr (hopefully no noise)
400V at thr = 970mV yielded 24% effi
