User Manual 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 select Pulse 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. Turn the Trigger Level Knob to adjust the trigger level to the desired place. 5. Press the Polarity softkey to select Positive or Negative pulse that to trigger on. 6. Press the When softkey, turn the Multifunctional Knob to select the desired 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. For example, for a positive pulse, if you set t (pulse real width) > (greater than a time value) : trigger when the positive or negative slope 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) >100ns, the waveform will trigger. != (not equal to time value) : trigger when the positive or negative slope time of the input signal is not equal to the specified time value. = (equal to time value) : trigger when the positive or negative slope time of the input signal is equal to the specified time value.
For example, for a positive pulse, if you set t (pulse real width) = 200ns, the waveform will trigger. 7. Press of 50% softkey to set the trigger level to the vertical midpoint between the peaks of the trigger signal. The trigger level values are displayed at the upper right corner of the screen. 8. Press the Width soft key and select V0 to set the reference width of the pulse signal. The pulse width of the data source must be ≥ 5ns so that the oscilloscope can detect the pulse. ＝ , ≠: Within a ±5% tolerance, triggers the oscilloscope when the signal pulse width is equal to or not equal to the specified pulse width. 22 / 67
