About trigger mode
Auto : Even if no trigger condition is detected, the oscilloscope can still acquire waveforms. If there is no
trigger condition, after the oscilloscope waits for a certain period of time, it will trigger itself and start collecting data.
Since there is no correct trigger, the waveform displayed by the oscilloscope scrolls on the screen because it cannot
be synchronized. Once a legal trigger signal is detected, the waveform can be stabilized on the screen. Users can use
this mode to monitor low-frequency random signals or observe the amplitude of signals, such as the waveform of a
DC power supply.
Normal : The waveform data is collected only after the trigger signal is detected. If no trigger occurs, the
oscilloscope will not acquire a new waveform. The display content will not be refreshed.
Single : In single mode, once the trigger condition is detected, the oscilloscope starts waveform data acquisition.
When new data is acquired, the latest waveform will be automatically maintained.
About automatic waveform capture
1. Automatic waveform capture is only available in AC gear, and the automatic waveform capture time is about 5-15
seconds.
2. Automatic waveform capture signal requirements: amplitude greater than 0.3VPP. frequency greater than: 10Hz.
