I) Acquiring Signals System
Showing as the follow picture, the “ACQUIRE” button for Acquiring Signals system is at the menu.
When you acquire a signal, the oscilloscope converts it into a 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.
Disadvantage: This mode does not acquire rapid variations in the signal that may occur between samples.
This can result in aliasing may cause narrow pulses to be missed.
In these cases, you should use the Peak Detect mode to acquire data.
