• Sample points
Normal mode acquires a single sample point in each interval.
The maximum sample rate is 25 MS/s. At 10 µs and faster settings, this sample rate does not
acquire 480 points. In this case, a Digital Signal Processor interpolates points between the
sampled points to make a full 480 point waveform record.
