trigger information source is
the input channel CH1.
the commonly used channel
information source is input channel
CH1
The
channel selected as trigger information source
are under normal operation only its.
corresponding input channel have been opened.
decides activity modes of
oscilloscope under no trigger event status. Three
trigger modes: automatic, normal and single
trigger.
Automatic trigger: when no trigger signal input
status, the system shall collect waveform data
automatically, enabling to display scan baseline
on the screen
when there is trigger signal
the
automatic shall switch to trigger scanning and sync
with signal.
when scan waveform is set at the 50ms/div
or slower time base
oscilloscope shall enter
into SCAN mode
oscilloscope shall collect
waveform under normal trigger mode only
trigger conditions have been met
When there is
no trigger signal, it stops collecting data and awaits
trigger. While there is trigger signal, it shall
produce trigger scan.
under the single trigger mode,
press
operation
key once oscilloscope shall
await trigger and when detecting a trigger
it
shall collect and display the collected waveforms,
then stop it.
it decides which
components of signal will be transmitted to trigger
circuit
Coupling types include: DC, AC and high
frequency restriction.
pass all components of signal.
