26 / 72
than the specified time value.
> (greater than a time value): trigger when the positive or negative slope time of the input signal is
greater than the specified time value.
!=(not equal to a time value): trigger when the positive or negative slope time of the input signal is not
equal to the specified time value..
=(equal to a time value): trigger when the positive or negative slope time of the input signal is equal to
the specified time value.
7. Press the Time softkey and turn V0 to set the reference value of the slope time.
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.
