I have searched for this topic in the forum and FAQ but I have just found this information:
Note: Digital channel entries are only recorded in the export file when data changes. Therefore, the number of entries in the resulting export file are dependent on the number of transitions that occur and not on the number of digital samples in the capture. This helps reduce the file size of the export file.
However, when exporting my measurements with Logic 2.3.37 I have encountered some ‘downsampling’. The original measurement gathered in Logic 2.3.37 is this, with a square signal quite well defined:
When exporting the signal and representing the data I got something like this:
And it is possible to see that the .csv file is missing some values:
The channel values presented in the other graphs are highlighted in red, and the data values that seem missing some ‘extra’ 1s are highlighted in purple.
This is of course a very tiny portion of the whole signal, and most of it is well exported. I was wondering if there is something I am doing wrong while exporting, if this is an issue already reported and if there is any solution to this.
My next step is going to try to record the signal as analogue to choose the sample rate when exporting.
Thank you very much in advance for your time and attention.
