The trigger setting of a DSO decides when the data
of the waveform starts to be collected and displays on
the screen. Once the trigger is correctly set, it can convert
unstable display into meaningful waveform display. Data
acquisition of a DSO starting trigger conditions satisfied.
After a signal trigger is detected, DSO will continuously
collect data and display the waveform on the right of the

trigger point. The trigger control area of the DSO operation
panel includes: trigger level adjustment knob; trigger
menu key: TRIG MENU for 72-10510/72-8225A/
72-8705A/72-8710A and [MENU] for 72-2650. For the
72-10510/72-8225A/72-8705A/72-8710A DSO, it can
set the trigger level to be at 50% of signal vertical midpoint
by the 50% button. For the 72-10510/72-8225A DSO, it
is achieved by pressing SET TO ZERO key. Forcing
trigger shall be achieved by pressing FORCE button.
FORCE trigger is a trigger signal generated by force
and is mainly applied in trigger mode and "normal" and
"single" mode.
