Latest tests of PH optimization |
|
|
We did some tests by running the latest version of pXar on modules M1521, M1529, M1534 and M1536, specifically trimming and PH optimization. Of the 4 modules tested, the PH optimization converged only for M1521. We plan to further investigate with Urs' help possible reasons for failed PH optimization.
We also noticed a change in the threshold distribution plot of the latest trim bit test compared to the previous version of the test (see attached plots). |
