Acquisition System

Introductory on how to use the acquisition control and set the sampling system of the
handheld oscilloscope.
Overview
To understand the oscilloscope's sampling and acquisition modes, it is helpful to
understand sampling theory, sample rate and oscilloscope bandwidth and sample rate.
Sampling Theory
The Nyquist sampling theorem states that for a limited bandwidth (band- limited) signal
with maximum frequency f , the equally spaced sampling frequency f must be greater
MAX S
than twice the maximum frequency f , in order to uniquely reconstruct the signal
MAX
without aliasing.
f = f = Nyquist frequency (f ) = folding frequency
MAX S/2 N
Sample Rate
The maximum sample rate of the oscilloscope is 1GSa/s. The actual sample rate of the
oscilloscope is determined by the horizontal scale. Press the Horizontal Scale Button
to adjust the sample rate.
The actual sample rate is displayed in the information area at the bottom right corner of
the screen.
