NOTE. Peak Detect and Hi Res modes take advantage of sample points that the oscilloscope would have discarded at lower
sweep s
peeds. Therefore, these modes only work when the current sample rate is less than the m aximum possible sample
rate. As soon as the oscilloscope starts to acquire at the maximum sample rate, then the Peak Detect, Hi Res and Sample
modes all look the same. You can control the sample rate by setting the Horizontal scale and the Record Length.

5. Push Record Length.
6. Scroll through the available choices.
Choose among 1000, 10 k, 100 k, 1 M,
10 M, and 20 M points.
