Neo software releases prior to the above may exhibit non-compliant intermittent AM/CWM removal timestamp compensation at the instrument receiver at the following rates: 100G FEC, 25G FEC, 50G and 40G, resulting in spurious time errors (dTE) of up to 12.8ns. Occurrences are very intermittent (intervals of up to several hours), are dependent upon PTP packet/marker coincidence - which may not happen, and are evident in measurements that the time errors cause an issue for. However, to guarantee DUT performance release 9.00.36 or greater is recommended.
