Sample Rate
Sample refers to the process that the oscilloscope converts analog signals to digital
signals at a certain time interval and stores the data in order. Sample rate is the
reciprocal of the time interval.

The analog channels sample rate of this oscilloscope is up to 4 GSa/s. Note that the
sample rate is displayed in the status bar at the upper side of the screen and in the
Sa Rate menu and can be changed by adjusting the horizontal time base (s/div)
through HORIZONTAL
SCALE or modifying the “Memory Depth”.
The influence on the waveform when the sample rate is too low:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost and the waveform displayed is rather different from the actual
signal.
