- Reception test for 1541, 1542, 1543 OK
- Cap gluing
- FT:
-- 1539: C/B/B. First -20 is C due to INCOMPLETE TEST: DTB stuck
==> Must be retested at -20C and then files merging
-- 1541: C/C/C. Electrical Test is C due to Trimbit test failure in ROC13. Threshold is reasonable (see attachment)
==> Manually regraded to B
-- 1542: C/C/C. Electrical Test is C due to RelGain of 0.200 instead of <0.1 (too wide Gain distribution).
-- 1543: B/B/B (-20/-20/+10). Electrical Test is B due to mean noise >200e. |
