6.2 Trigger
The IFD module provides 2 additional configurable 5V @ 50Ω (15V optional) trigger. These trigger
signals have a configurable duration and the timing of the leading edge (in respect to the master trigger
from the PCI receiver card) can be configured too. The following parameter are used to configure the
triggers.
6.2.1 TrigXEnable
Enable/disable trigger x (e.g. Trig0Enable or Trig1Enable)
Type: boolean
Default: false
6.2.2 TrigXDuration
Duration of the trigger in µs (range 0...100µs). Resolution approx. 15ns
Type: float
Default: 1
Unit: µs
6.2.3 TrigXStart
Start of the leading edge in respect to the leading edge of the master trigger. (range -100...100 µs)
Type: float
Default: 0
Unit: µs
