1 Trigger Source Input channel is used as the
trigger source
Input channel (CHI) is the most
commonly used trigger source. For the channel
selected as the trigger source, it should be
switched on before it works normally.
2 decide what the oscilloscope will
do when no trigger event occurs. Three trigger
modes are offered: Auto, Normal and Single
The system automatically acquires data
even there is no signal input and therefore displays
scan reference line on the screen when the
trigger occurs it converted into trigger scanning
and synchronizes with the signal on its own
Note: The Oscilloscop
e will go into SCAN mode if
waveform scan rate is set at 50ms/div or lower
timebase
Under this mode, the Oscilloscope
acquires the waveform only after the trigger
conditions are met. It stops to acquire and keeps
waiting if no signal is input Once the trigger
occurs, the scan starts.
You just need to press RUN button if
under single mode then the Oscilloscope waits
to trigger. It begins to acquire and display all
acquired waveforms once single-shot trigger signal
is detected, after that, it stops.
3 To decide to pass which
kind of components through the trigger circuits
The types include: DC, AC an
d Hf Reject.
passes through all components of the
signal
AC blocks DC component and attenuate
signals at 10Hz
attenuates high frequency
component at 80kHz
