The MDO-2000A SERIES generates an
internal trigger if there is no trigger
event, to make sure waveforms are
constantly updated regardless of
trigger events. Select this mode
especially when viewing rolling
waveforms at slower timebases.
Normal
The MDO-2000A acquires a waveform
only when a trigger event occurs.
