2.7.8. Interval Trigger
Trigger when the time difference between the neighboring rising or falling edges meets the time limit condition (<, >, !=, =).
To set interval trigger:
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 Interval and push down the knob to confirm.
3. Press the Source softkey, turn the Multifunctional Knob to select CH1~CH2 as the trigger source.
4. Press the Slope softkey to select rising or falling edge.
5. Press the When softkey, turn the Multifunctional Knob to select desired condition.
< (less than a time value): trigger when the positive or negative pulse time of the input signal is less than the specified time
value.
> (greater than a time value): trigger when the positive or negative pulse time of the input signal is greater than the
specified time value.
!= (not equal to a time value): trigger when the positive or negative pulse time of the input signal is not equal to the
specified limit of time.
= (equal to a time value): trigger when the positive or negative pulse time of the input signal is equal to the specified limit of
time.
6. Press the Time softkey and turn V0 to set the reference value of the time.
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.
2.7.9. Under Amp Trigger
The Under Amp trigger looks for pulses that cross one threshold but not another as shown in the picture below.
