Starting time of the external TTL trigger for DT9837A or B

[daquser]

Is it possible to delay the starting time of external TTL trigger a little bit, so that some transient data a little before the rising or falling edge of the TTL can also be acquired? If yes, could you provide sample code in Matlab?

Hello,

There is no trigger delay feature with the DT9837A, B, or C. Instead, you could investigate how to delay a digital signal. For example, putting a circuit in line with the DT9837 trigger input to delay the trigger pulse. Another approach could be to capture more data and discard the data at the beginning.  

Best regards,
