Part II: Settings and Measurements
Trigger Recording Setup
Trigger Condition
In the figure above, the purple rectangle indicates the trigger condition. If the signal amplitude is higher
than the amplitude range covered by this area, or if the signal enters the trigger area from the left or right
sides, then persistence recording will not trigger. Recording will only occur if the signal enters the "rectangle
from below, and does not reach higher than the top side. If these conditions are met, the signal will trigger
the persistence recording function.
Setting Up the Trigger Pattern
1.
In Record > Trigger > Setup, press
Min Freq
(F2) and use the arrow keys to shift the rectangle’s left side
(minimum frequency) left or right. You can also turn the rotary knob for more sensitive adjustments, 10%
the speed of the arrow keys. Then press
Max Freq
(F3) and define the rectangle’s right side (maximum
frequency).
2.
Press
Max Level
(F4) and use the arrow keys and rotary knob to shift the rectangle’s top side (max signal
level) up or down. Then press
Min Level
(F5) and define the rectangle’s bottom side (min. signal level).
3.
Press
Move
(F6). Here, you can adjust the entire trigger zone’s position on the measurement grid. Use
the arrow keys to move it up or down, and the rotary knob to move it left or right.
