Data Logged To File using a Reference Trigger with SignalExpress Is Corrupted

Primary Software: LabVIEW Signal Express>>Development System
Primary Software Version: 1.1.1
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I logged data to file using a reference trigger in Signal Express 1.1.1. When I try to open the file in SignalExpress it says the file is corrupted. I opened the file in a text editor and it is missing all of the pretrigger samples. Why is this happening?

Solution:
SignalExpress 1.1.1 is not able to log pretrigger samples. This results in a mismatch between what the header of the data file says and the number of samples in the data file. You should still be able to open the file in a text editor. If you open the file in the text editor you will find that all of the pretrigger samples are missing. SignalExpress Patch_1.1.1.003 fixes this behavior. Please visit the SignalExpress 1.1.1 Drivers and Updates page linked below to download and read more about this patch.
