Minimum and Maximum Values in CSV Files
If you are running a Quick Measurement Minimum or Maximum
measurement, the minimum and maximum values shown in the
Quick Measurement display may not appear in the CSV file.
Explanation:
When the oscilloscope’s sample rate is 4 GSa/s, a sample will be
taken every 250 ps. If the sweep speed is set to 100 ns/div, there
will be 1000 ns of data displayed (because there are ten
divisions across the screen). To find the total number of
samples the oscilloscope will take:
For measurement data, the oscilloscope will decimate the 4000
points to 1000 points that will fit on the display. This
decimation will not lose track of the min and max values at each
of the 1000 horizontal data points, and min and max values will
be displayed on screen. However, the oversampled data is also
processed to provide a best-estimate value at each of the 1000
horizontal points. The data in the CSV file will be the
best-estimate value at each of the 1000 horizontal points.
Therefore, the min and max values may not appear in the CSV
file.
This occurs when oversampling occurs
(10 * seconds per division * maximum sample rate > 1000).
