Sweep mode when EVENT trigger is used
When using an EVENT trigger, set the sweep mode to Normal or Single.
If Auto is set, waveforms are acquired automatically even if it does not satisfy
the specified condition and it is not possible to acquire the specified phenomenon
correctly.
MISSING
Automatically generates valid trigger signal when there is no trigger
signal within specified time. The valid trigger is generated within 50ns
after the interval time has passed from the last trigger. It allows waveform
to be acquired when part of repetition signal is missing due to power
interruption or data dropout.
