The Pulse Trigger type triggers on the positive or negative pulse with a specied width.
Figure 6.11 Pulse Trigger
1. Press the Setup key to enter the Trigger Menu.
2. Press the Type softkey to view the available trigger types.
3. Turn the Universal Knob
4. Select Pulse and push the Universal Knob to select the trigger source.
5. Turn the Trigger Level Knob to adjust the trigger level to the desired place.
6. Press the Polarity softkey to toggle between Positive and Negative pulse.
7. Press the Limit Range softkey and 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 specied time value. For example, for a positive pulse, if you set t (pulse real width) 100ns, the waveform
will trigger.
Figure 6.12 Less than a Time Value
• >= (greater than a time value): Trigger when the positive or negative pulse time of the input signal is greater
than the specied time value. For example, for a positive pulse, if you set t (pulse real width) 100ns, the waveform
will trigger.
Figure 6.13 Greater than a Time Value
• [- -.- -] (within a range of time value): Trigger when the positive or negative pulse time of the input signal is
greater than the specied lower limit of time and lower than the specied upper limit of time value.
