Erroneous 2-sample delay in Epoc_Store_With_Offset timestamp

Tech Note: TN0877
Product: OpenEx, RPvdsEx
Version: < 72
Date Added: 2010-10-07

Issue

When using the Epoc_Store_With_Offset macro, the onset timestamp is delayed by two samples. This can cause the onset to appear to have occurred two samples before it actually did and will not by synchronized with other Epoc_Stores in the circuit.

Solution

Upgrade to the latest version of TDT Drivers and OpenEx. This issue was resolved in v72.
