The current trigger polarity is displayed at the upper right corner of the screen.
6. Press the Limit Range softkey; turn the Universal Knob to select the desired
condition.
<= (less than a time value): Trigger when the positive or negative pulse time of
the input signal is lower than the specified time value.
For example, for a positive pulse, if you set t (pulse real width) ≤ 100 ns, the
waveform will trigger.
>= (greater than a time value): Trigger when the positive or negative pulse time
of the input signal is greater than the specified time value.
For example, for a positive pulse, if you set t (pulse real width) ≥ 100 ns, the
waveform will trigger.
[--,--] (within a range of time value):Trigger when the positive or negative
pulse time of the input signal is greater than the specified lower limit of time
