Select the slope type of signal. 
Select the type of trigger. The Normal mode is best for most 
pulse width trigger applications. 
AC 
DC 
Noise Reject 
HF Reject 
LF Reject 
Selects the components of the trigger signal applied to the 
trigger circuitry. 
Adjust  the  vertical  window  by  setting  two  trigger  levels. 
Select this option and press F3 to choose V1 or V2. 
Select the trigger condition. 
Press  F4  to  select  this  option.  Turn  the  multi-functional 
knob to set the time span. 
Overtime Trigger: In Pulse Width trigger, you may sometimes be puzzled with the long time for 
trigger, as you do not need a complete pulse width to trigger the oscilloscope, but want the trigger 
occurs just upon the overtime point. This is called Overtime Trigger. 
Select the trigger source. 
Select to trigger on positive or negative pulses. 
Press F5 to select Overtime option and adjust V0 to set the 
time. 
AC 
DC 
HF Reject 
LF Reject 
Selects the components of the trigger signal applied to the 
trigger circuitry. 
Holdoff: To use Trigger Holdoff, push the HORIZONTAL Menu button and set the Holdoff Time 
option by pressing F4. The Trigger Holdoff function can be used to generate a stable display of 
complex waveforms (such as pulse trains). Holdoff is the time between when the oscilloscope 
detects one trigger and when it is ready to detect another. During the holdoff time, the oscilloscope 
will not trigger. For a pulse train, the holdoff time can be adjusted to let the oscilloscope trigger only 
on the first pulse in the train.
