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.
2.7.4. Slope Trigger
The slope trigger looks for a rising or falling transition from one level to another level in the specified time range. In the series
of scope, positive slope time is defined as the time difference between the two crossing points of trigger level line A and B with
the positive edge as shown in the figure below.
1. Press the [Trig Menu] button on the front panel to enter the Trigger function menu.
2. Press the Type softkey, turn the Multifunctional Knob to set select Slop and then press the knob to confirm.
3. Press the Source softkey, turn the Multifunctional Knob to select CH1~CH2 as the trigger source.
4. Press the Slop softkey, turn the Multifunctional Knob to set select the desired trigger edge (rising or falling), and then push
down the knob to confirm.
5. Press the Level softkey and press of Lower Upper softkey to select Lower(V2) or Upper(V1) the trigger level; then turn the
Trigger Level Knob to adjust the position. The trigger different level value between Upper and Lower is displayed at the upper
right corner of the screen.
The Lower trigger level cannot be upper than the upper trigger level. V1 means the upper trigger level while V2 means the
lower trigger level.
6. Press the When softkey, then turn the Multifunctional Knob to select the desired slope condition, and push down the knob
to confirm.
< (less than a time value): trigger when the positive or negative slope time of the input signal is lower 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.
