Alıntı YapMemory depth / ((time per division setting) * 10 divisions) = sample rate (up to the max sample rate of the ADCs).
For example, let's assume a time base setting of 160uS/div and a max memory depth of 4,000,000 samples. That would be 4,000,000 / ((160uS/div) * 10 divisions) = 2.5 gigasamples/second.
