Sa Rate
Displays system sampling rate.
When you acquire a signal, the oscilloscope converts it into digital form
and displays a waveform. The acquisition mode defines how the signal is
digitized and the time base setting affects the time span and level of detail
in the acquisition.
 Sampling: In this acquisition mode, the oscilloscope samples
the signal in evenly spaced intervals to construct the waveform.
This mode accurately represents signals most of the time.
Advantage: You can use this mode to reduce random noise.
