8. Press the Mode softkey, turn V0 to select the trigger mode (auto, normal), and press V0 to confirm.
Auto: When the oscilloscope meets the trigger condition, it completes a trigger acquisition once; when the trigger condition
is not met, it can run the acquisition waveform freely.
Normal: When the oscilloscope meets the trigger condition, the input waveform is displayed; when the trigger condition is
not met, the original waveform is displayed.
9. Press the Holdoff softkey and turn V0 to set the time that the oscilloscope waits before a trigger to the next trigger, so that
complex waveforms are displayed stably.
2.7.5. Overtime Trigger
Trigger when the time interval (△T) from when the rising edge (or falling edge) of the input signal passes through the trigger
level to when the neighboring falling edge (or rising edge) passes through the trigger level is greater than the timeout time set,
as shown in the figure below.
1. Press the [Trig Menu] button on the front panel to enter the Trigger system function menu.
2. Press the Type softkey, then use the Multifunctional Knob to select Overtime and push down the knob to confirm.
3. Press the Source softkey, turn the Multifunctional Knob to select CH1~CH2 as the trigger source. Select channel with
signal input as trigger source to obtain stable trigger.
4. Press the Polarity softkey to select Positive or Negative edge.
5. Press the Time softkey, turn the Multifunctional Knob to select the desired value.
6. Press of 50% softkey to set the trigger level to the vertical midpoint between the peaks of the trigger signal.
7. Press the Mode softkey, turn V0 to select the trigger mode (auto, normal), and press V0 to confirm.
Auto: When the oscilloscope meets the trigger condition, it completes a trigger acquisition once; when the trigger condition
is not met, it can run the acquisition waveform freely.
Normal: When the oscilloscope meets the trigger condition, the input waveform is displayed; when the trigger condition is
not met, the original waveform is displayed.
8. Press the Holdoff softkey and turn V0 to set the time that the oscilloscope waits before a trigger to the next trigger, so that
complex waveforms are displayed stably.
2.7.6. Window Trigger
Windows trigger provides a high trigger level and a low trigger level. The instrument triggers when the input signal passes
through the high trigger level or the low trigger level.
