trigger_delay generator_synchronization in DAQ

[TDLAS_DE]

Hi all,

I use a delay generator (P400, highland technology) to generate four separately programmable delay-and width outputs. This four outputs will be connected to a laser controller (LDC-3908, ILX lightwave), which control 4 different lasers. Now I use the internal trigger in the delay generator at first. All detected laser signals will be measured by DAQ system.  And I have the synchronization problem in data acquisition. Can we send an external trigger from PCI 6115 to the delay generator in a LabVIEW program?

Thanks!

Hello,

you can use the DAQmx counter output event to generate a trigger signal based on your input signals. See for more detail here:

Without more detail about your synchronization problem it is difficult to provide more information.

Kind regards

Thanks for your reply. I found a simple solution. I connect the leading edge T0 (dely generator) to the PFI 0 (Digital input on BNC 2110) als a start input trigger. There are two Analog input  (We use two detectors and AI0 and AI1 on BNC2110) and I use the following vi:

Unfortuntly there still synchronization problem...
