Dear All,
We are experiencing unexpected behavior with the time stamps in the
meta file headers. It
appears that in cases where the flowgraph experiences data drops, the
timestamp is properly
updated. However, in cases, where the flowgraph hits the maximum
segment size (4 MB in our case),
the calculation of timestamp is done in such a way that appears to
neglect a decimation factor
in one of our blocks (keep_1_in_n). Details can be found below.
Any suggestions as to what’s
going on or what to do about it would be most appreciated.
Sincerely,
Dan Marlow
