• The horizontal time/div (sweep speed) setting. At faster settings, fewer data
points appear on the display.
• When saving to a CSV format file, the maximum number of data points is 64K.
When necessary, the Length control performs a "1 of n" decimation of the data .
For example: if the Length is set to 1000, and you are displaying a record that is
5000 data points in length, four of each five data points will be decimated,
creating an output file 1000 data points in length.
When saving waveform data, the save times depend on the chosen format:
