Question   Is there a relation between the time stamp (or sample time) in the Excel File and the Time Base chosen?
Answer
 
Question:
I have a question regarding the Excel Dump done from the software. I cannot find the time stamp in it or the sample time. Also, when I change the Real Time Recorder value in Ksamples/per seconds. I suppose, I cannot see any change in the generated Excel File. Is there a relation between the time stamp (or sample time) in the Excel File and the Time Base chosen?
 
Answer:
In the software, there are three commands to save data as excel file:
1:Save|Save as Txt: Here is saving current waveform/data displayed on the current screen. We can save the data at the auto/normal/single mode or the hold mode. The saved file only records the date and time while we execute the command.
