Run/Stop
5. Press the Run/Stop key several times and observe that the pulse
signal amplitude and width remains stable, due to high
sampling rate 1GSa/s.
Run/Stop
6. Change the horizontal scale to 100ns/div. Due to the additional
data memory requirement, the sampling rate falls from 1GSa/s
to 250MSa/s.
TIME/DIV 1GSa/s → 250MSa/s
7. Press the Run/Stop key several times and observe the pulse
signal. The signal amplitude and width becomes somewhat
unstable due to slower sampling rate 250MSa/s.
