means the AC power source This
trigger mode is suitable for observing signals
related to the AC power e g the correlation
between lighting equipment and power source
equipment to achieve stable synchronization
2. Determine the action of your
oscilloscope at trigger. This oscilloscope offers three
trigger modes for selection : auto, normal and single.
The system will acquire and
display waveform data automatically when
there is no trigger signal input When the
trigger signal is generated, it automatically turns
to trigger scan for signal synchronization.
Time base of the scan range can b
e set to
50ms/div or slower to generate a roll waveform.
In this mode your
oscilloscope samples waveforms only when
triggering conditions are met. The system stops
acquiring data and waits when there is no trigger
signal. When the trigger signal is generated,
trigger scan occurs.
In this mode you only have
to press the RUN button once and the
oscilloscope will wait for trigger. One sampling
will occur and the acquired waveform will be
displayed when the digital storage oscilloscope
detects a trigger. Then trigger will stop.
3. Trigger coupling determines
which quantities of the signal are tr
ansmitted to
the trigger circuit. Coupling modes are DC, AC,
low frequency suppression and high frequency
suppression.
:Allowing all quantities to pass
:Intercepting DC quantities and attenuating
signals under Hz
:Intercepting DC quantities and
attenuating low frequency quantities under
kHz
:Attenuating high frequency
quantities over kHz
