For trigger indices NDIGO TRIGGER TDC to NDIGO TRIGGER BUS3 PE the threshold is ig-
nored.
ndigo bool t edge
If set this trigger implements edge trigger functionality else this is a level trigger.
For trigger indices NDIGO TRIGGER AUTO and NDIGO TRIGGER ONE this is ignored.
For trigger indices NDIGO TRIGGER TDC PE to NDIGO TRIGGER BUS3 PE this must be set.
ndigo bool t rising
If set trigger on rising edges or when above threshold.
For trigger indices NDIGO TRIGGER AUTO and NDIGO TRIGGER ONE this is ignored.
For trigger indices NDIGO TRIGGER TDC PE to NDIGO TRIGGER BUS3 PE this must be set.
3.4.3 Structure ndigo trigger block
ndigo bool t enabled
Activate triggers on this channel.
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
Precursor in multiples of 3.2ns. The amount of data preceding a trigger that is captured.
The precursor setting is ignored for the timestamp channel.
int length
In multiples of 3.2ns.
The total amount of data that is 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 3.2ns wide, 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.
