Why is There Multiple Timestamp Rows in the ASCII Header File *.HDR?

Resources:

When viewing the ASCII Header File *.HDR, each timestamp row corresponds to the time a trigger occurs. Multiple timestamp rows will be created if the trigger mode is set to Single(N) and History is set to "All." The DL750 Scopecorder will save the trigger times of N waveforms into separate timestamp rows in the ASCII header file.

If the record length is set short on the DL750 Scopecorder , the memory is divided into blocks, and waveform data is saved into individual blocks each time a trigger occurs. In sequential store function, Single(N) trigger mode, you can specify the waveform acquisition count (block number), and the measurement stops when the specified count is reached.


Please download the sample HDR file, and open it using Notepad for an example of multiple timestamp rows.
