Trigger point
Press the front panel Trig Menu button to enter the trigger function menu.
[Type] Select the pulse width and press V0 to confirm.
[Data source] Select CH1～CH4 or LA as the trigger source.
Note: LA must be inserted when LA is used as the trigger source.
[Polarity] Select the positive or negative polarity of the trigger.
[When] Select the trigger conditions [＞, ＜, ＝, ≠], And press V0 to confirm.
＞ [Greater than the set time value]: When the positive or negative pulse width of the
input signal is greater than the set pulse width, it can be triggered (pulse width error is
5%).
＜ [Smaller than the set time value]: When the positive or negative pulse width of the
input signal is smaller than the set pulse width, it can be triggered (pulse width error is
5%).
＝ [Equal to the set time value]: When the positive or negative pulse width of the input
signal is equal to the set pulse width, it can be triggered (pulse width error is 5%).
≠ [Not equal to the set time value]: When the positive or negative pulse width of the
input signal is not equal to the set pulse width, it can be triggered (pulse width error is
5%).
[Width] Set the pulse width time from 8ns to 10s.
[50%] Set the trigger level to the vertical midpoint of the peak-to-peak value of the trig-
ger signal. The trigger level value is displayed in the upper right corner of the screen.
[Mode] Select the acquisition mode [Auto, Normal] and press V0 to confirm.
[Holdoff] Set the holdoff time.
