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 using the
MULTIPURPOSE control.

Setup
Edge
CH1, CH2
Set CH1, 2, 3 or CH4 as the signal source trigger signal
CH3, CH4
EXT, EXT/5
Set the external trigger input channel as the signal source
LINE
Set to AC power trigger
CH1 & CH2
CH1 & CH2 trigger their respective signals alternately
CH3 & CH4
CH3 & CH4 trigger their respective signals alternately
Grid
Set up as grid trigger
Alternate
Ch1, CH2 trigger their own signals alternatively
Rising
Set to trigger on the signals rising edge
Falling
Set to trigger on the signals falling edge
Rise & Fall
Set to trigger on the signals rising and falling edge
Auto
Set to sample waveform only if no trigger condition is
detected
Normal
Set to sample waveform only if trigger condition is satisfied
Single
Set to sample waveform once when detecting one trigger
and then stop
DC
Allow AC and DC quantities of the input signal to pass
AC
Intercept DC quantities of the input signal
H/F reject
Reject high frequency quantities above 80kHz of the signal
L/F reject
Reject low frequency quantities below 80kHz of the signal
Setup
Pulse
CH1, CH2
Set CH1, 2, 3 or CH4 as the signal source trigger signal
CH3, CH4
EXT, EXT/5
Set to external trigger or divide the external trigger by 5
LINE
Set to AC power source
CH1 & CH2
CH1 & CH2 trigger their respective signals alternately
CH3 & CH4
CH3 & CH4 trigger their respective signals alternately
Larger
Trigger when pulse width is larger than default value
Smaller
Trigger when pulse width is smaller than default value
Equal
Trigger when pulse width equals to default value
Set positive pulse as the trigger signal
Pos pulse width
Set negative pulse width as the trigger signal
Neg pulse width
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
generates 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.
