A digital storage oscilloscope is specified to have a sample rate of 400 MS/s and an acquisitionmemory of 20K. (a) Determine the slowest possible time-base setting for which the specified samplerate is achievable. (b) If the time-base setting were 1 ms per division, what sampling rate would beachievable in this case?(a) 5s/div; (b) 2 MS/s4. A transient of 100 ms is to be captured on a digital storage oscilloscope on full screen in thehorizontal direction. If the transient is to be recorded at a sampling rate of 100 kS/s, what shouldthe minimum size of the acquisition memory be?10KFurther Reading1. Tomal, D. and Widmer, N. S.
