Trigger
40
Single
The oscilloscope waits for a trigger and displays the waveform when the trigger condition is met, the acquisition is stopped
when the trigger conditions are met.
Single
trigger mode is appropriate when:
• Capturing a single event or a periodic signal.
• Capturing a burst or other unusual signals.
Note:
The oscilloscope can be forced to trigger by pressing the Single button twice. The trigger status in the upper left
corner of the screen will be displayed as "FStop".
6.3 Trigger Level
Trigger level and slope define the trigger point.
Figure 6.3
Trigger Point
Turn the Trigger Level Knob to adjust the trigger level for the selected analog channel.
Pushing the Trigger Level Knob sets the trigger level to 0 when AC Coupling is selected.
The position of the trigger level for the analog channel is indicated by the trigger level icon
(if the analog channel is
on). The value of the analog channel trigger level is displayed in the upper- right corner of the display.
The example in figure
highlights the Positive edge slope at a trigger level of 2.00 mV.
