Detailed Description

This section contains all trigger hold off related functions.

Trigger hold off defines a period of time after starting a measurement in which the oscilloscope will not respond to triggers. It is used to get stable triggering on periodical signals that have multiple moments that would otherwise generate a trigger.

When pre samples are selected, trigger hold off can be used to ensure that all pre samples are measured before a trigger occurs. Set the trigger hold off to TH_ALLPRESAMPLES to measure all pre samples and have no invalid pre samples.

Trigger hold off is set in a number of samples. By default the trigger hold off is set to: 0 samples.
