Pulse Trigger
•
Pulse trigger means determining the triggering time based on the pulse width. You
can acquire abnormal pulse by setting the pulse width condition.
•
Adjust the pulse width from 2ns~10s by turning the control on the upper front panel.

Setup
Pulse
CH1
Set Ch1 as the signal source trigger signal
CH2
Set CH2 as the signal source trigger signal
EXT/EXT5
Set the external trigger input channel as the signal
source trigger signal or divided by 5
AC line
Set up as AC grid trigger
Alter
Ch1, CH2 trigger their own signals alternately
DC
Accept AC and DC signal components
AC
Prevents DC signal components
Low frequency
Restricts low frequency component lower than 80kHz
restriction
within the signal source
High frequency
Restricts high frequency component higher than 80kHz
restriction
within the signal source
Pos pulse width
Set positive pulse as the trigger signal
Neg pulse width
Set negative pulse width as the trigger signal
Auto
The system automatically samples waveform data
when there is no trigger signal input. The scan baseline
is shown on the display. When the trigger signal is
generated it automatically turns to trigger scan.
Normal
The system stops acquiring data when there is no
trigger signal. When the trigger signal is generated
trigger scan occurs.
Single
One trigger will occur when there is an input trigger
signal. Then trigger will stop.

Setup
Positive pulse
Set to positive pulse width as trigger information source
width
Negative pulse
Set to negative pulse width as trigger information source
width
<
To trigger when the input signal pulse width is smaller
than the set value of pulse time
>
To trigger when the input signal pulse width is larger
than the set value of pulse time
=
To trigger when the input signal pulse width is equal to
the set value of pulse time
20ns~10.0s
Set to trigger on the signals rising edge
Set to trigger on the signals falling edge
Set to trigger on rising and falling edge
