Trigger Setup
Use Trigger to determine when the Analyzer should start displaying waveforms on the screen so that
the waveforms displayed by each refresh can be aligned. Once the set trigger condition is met, the
screen is triggered, the waveform displayed on the screen is aligned at that point.
The Analyzer offers a variety of trigger methods to support multiple trigger sources and trigger modes.
Enter the Trigger Setup Menu:
•
From the main screen of Scope select

( Trigger ).
The options are as shown in

Trigger Level
The up and down arrow keys increase or decrease the trigger level. Each time
the key is pushed, the trigger mark on the screen moves in the up/down
direction.
Note
If the trigger level is not set properly, under the “Auto” mode, the starting point of the
waveform displayed (signal level at the left side of the screen) may be unstable, it will
jitter left and right; the waveform may not be displayed at all under “Normal” mode.
