I'm having trouble understanding the files for the GW Instek GDS-1054B Oscilloscope. I believe I understand the Detailed files but I cant seem to make heads or tails of the Fast CSV format. I am trying to use this to test the output of an automotive speedometer speed sensor. I have taken voltage output at several speeds measuring the VRS speed senor output and stored the data in both detailed and fast CSV format.
I believe the detailed files are giving me exactly what I want but I would like to be able to use the Fast CVS files for when I need to take data at higher rates. The detailed files give me both voltage and time. The Fast CVS only gives the voltage data in an integer format. Both files give me a vertical scale. If I scale the data by the vertical scale it seems fix the data for the Fast CSV files but it mutilated the data for the detailed CSV files. OK so I get that the Detailed CSV files are OK as is and no need to scale. But with the Fast CSV data I scale the data by multiplying by the Vertical scale factor. That makes the data linear and looks like something that I can use, except its too high like 1000V pk-pk. I found that when I scale the Fast CSV and then divide by 25 the output is the same as the detailed CSV. I cannot find anything in the docs to get the correct voltage output from the fast CSV.
Attached are two files one is fast and one is detailed. The excel file shows what happens when you calculate the output at similar frequencies and scale using the vertical scale from each file.
I hope this all makes sens and I hope someone can help.
