16.4.5 Functional Buttons
This group of buttons includes trigger setting buttons allowing you to set
trigger source and trigger mode, a Time base button for adjustment, and a
Measurement button with options for various measurement types.
Trigger On/Off
– taps to turn on/off the trigger. The button displays as
Trigger Off when it is activated, and vice versa.
Once the trigger is activated, a voltage scale reference line and a time
base reference line will be displayed on the measurement grid, the cross
point of the 2 lines indicates the trigger point, allowing users to adjust its
position by moving each of the 2 lines.
Trigger Source
– assigns the trigger to a specific channel
Trigger Slope
– sets trigger to occur by rising or falling voltage edges
Trigger Mode
– configures the trigger mode:
A.
Normal Mode
– configures the trigger to occur every time when the
captured signal waveform reaches the trigger point, so the scope
starts to draw the waveform when the signal reaches the trigger
point.
