ndigo bool t retrigger

If a new trigger condition occurs while the postcursor is acquired the packet is extended by

starting a new postcursor. Otherwise the new trigger is ignored and the packet ends after the

precursor of the ﬁrst trigger.

The retrigger setting is ignored for the timestamp channel.

ndigo bool t reserved1

Defaults to false. Do not change.

ndigo bool t reserved2

Defaults to false. Do not change.

int precursor

The amount of data preceding a trigger that is captured.

The precursor setting is ignored for the timestamp channel.

int length

The total amount of samples that are recorded in addition to the trigger window. Precursor

determines how many of these are ahead of the trigger and how many are appended after the

trigger. In edge trigger mode the trigger window always is one sample, in level trigger mode it

is as long as the trigger condition is fulﬁlled.

The length setting is ignored for the timestamp channel.

int sources

A bit mask with a bit set for all trigger sources that can trigger this channel.
