Trigger level
Press the front panel Trig Menu button to open the trigger function menu.
[Type] Select the interval 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.
[Slope] Select the positive or negative polarity of the trigger.
[When] Select the trigger condition (＞, ＜, ＝, ≠), And press V0 to confirm.
＞ [Greater than the set time value]: It can trigger when the interval between two rising
or falling edges is greater than the set reference time (pulse width error is 5%).
＜ [Smaller than the set time value]: It can trigger when the interval between two rising
or falling edges is smaller than the set reference time (pulse width error is 5%).
＝ [Equal to the set time value]: It can trigger when the interval between two rising or
falling edges is equal to the set reference time (pulse width error is 5%).
≠ [Not equal to the set time value]: It can trigger when the interval between two rising
or falling edges is not equal to the set reference time (pulse width error is 5%).
[Time] Set the reference time (8ns～10s).
[Mode] Select the acquisition mode (auto, normal) and press V0 to confirm.
[Holdoff] Set the holdoff time.
Trigger level knob: The analog channel can modify the trigger level value. Trigger the
mark and move up and down with the knob. Turn the trigger level knob to adjust the
trigger level to obtain a stable trigger.
Digital channel: You can change the trigger threshold of the digital channel by setting
the threshold voltage.
Under Amp trigger
Under Amp triggering is used to trigger pulses that cross one trigger level but not an-
other trigger level, as shown in the figure below:
