7. Trigger System
Trigger determines when the oscilloscope starts to collect data and display waveform. Once the trigger is
correctly setup, it can convert unstable signals into meaningful waveform. In the beginning of data
acquisition, it collects enough data to compose the waveform at the left side of the trigger point, and
continue to collect the data until the trigger condition is met. When a trigger is detected, the oscilloscope
continuously collecting enough data to draw the waveform at the right side of the trigger point.
In this chapter, take 4 analog channel (MSO2XX4CS) as example to introduce vertical channel setting.
