Adjust trigger level
The trigger level can be coarsely adjusted and finely adjusted.
Coarse adjustment: Slide up and down in the trigger level adjustment area.
Fine adjustment: After moving the trigger level, tap the fine adjustment button in the lower left corner of the screen
for fine adjustment of the trigger level.
Note: Fine adjustment requires activation of the trigger level control function.
In addition, if the final operation of the oscilloscope is to adjust the trigger level, tap and select the "level"
item to adjust the trigger level to 50% of the waveform amplitude of the trigger source channel.
Set trigger hold-off time
The trigger hold-off time can set up the waiting time of the oscilloscope after the trigger and before the trigger
circuit is reconnected. During hold-off, the oscilloscope does not re-trigger until the end of the hold-off time, and
the hold-off time can be used to stably trigger complex waveforms. The trigger hold-off time ranges from 200ns~10s.
The hold-off may be used to trigger on repetitive waveforms with multiple edges (or other events) between
waveform repetitions. If the shortest time between triggers is known, the hold-off may also be used to trigger on the
first edge.
For example, to obtain stable trigger on the repetitive pulse trigger shown below, set the hold-off time to a value
of >200ns but <600ns.
Figure 6-9 Trigger hold-off Time
Set trigger hold-off time:
1) Tap “Trigger” on the main menu to open the trigger menu. Under “Common”, tap the box after “hold-off Time”
to open the hold-offtime adjustment interface. The trigger time is displayed on the upper left, the fine
adjustment time scale is displayed on the upper right, and the coarse time scale is displayed below, as shown
in Figure 6-10.

When adjusting the time, drag or tap the coarse adjustment scale for coarse adjustment, and then drag the fine
adjustment scale for fine adjustment of the hold-offtime.
