Figure 42 - Trigger
Setup: Press this button to open the trigger menu. This menu lets you control
how the oscilloscope's capture system decides when to capture a waveform.
This oscilloscope provides a variety of trigger types: Edge, Slope, Pulse, Video,
Window, Interval, Dropout, Runt, Pattern and Serial Bus
(I2C/SPI/UART/RS232/CAN/LIN).
Auto: Auto triggering is a triggering method that always lets you see a trace on
the screen. If the normal triggering scheme does not trigger after a certain
time, the oscilloscope generates a trigger.
Normal: Normal triggering has the oscilloscope trigger (i.e., capture the
waveform into memory and display it) when the trigger conditions are met.
After the waveform is displayed, the oscilloscope arms the trigger and waits
for another trigger event and displays the next waveform when triggered.
Single: This is the same as normal triggering except the trigger is disabled after
the first waveform is captured. This allows you to see the details of the
waveform that caused the trigger. It is useful for capturing transient events
that don't repeat.
