Pulse Trigger 
Trigger on the positive or negative pulse with a specified width. In this mode, the 
oscilloscope will trigger when the pulse width of the input signal satisfies the 
specified pulse width condition. 
Trigger Type: 
Press Type, rotate   to select “Pulse” and press down  . At this point, the trigger 
setting information is displayed at the upper right corner of the screen. 
For example, 
. The trigger type is pulse trigger; the trigger source 
is CH1; the trigger level is 168 mV. 
Source Selection: 
Press Source to open the signal source list and select CH1-CH4 or D0-D15. For the 
details, please refer to the introduction in “
Trigger Source”. The current trigger 
source is displayed at the upper right corner of the screen. 
Note: Select channel with signal input as trigger source to obtain stable trigger. 
Pulse Condition: 
In this oscilloscope, positive pulse width is defined as the time difference between 
the two crossing points of the trigger level and positive pulse; negative pulse width is 
defined as the time difference between the two crossing points of the trigger level 
and negative pulse, as shown in the figure below.

Press When to select the desired pulse width condition. 
  : trigger when the positive pulse width of the input signal is greater than 
the specified pulse width. 
 
: trigger when the positive pulse width of the input signal is lower than the 
specified pulse width. 
 
: trigger when the positive pulse width of the input signal is greater than 
the specified lower limit of pulse width and lower than the specified upper limit
