Hi Victor65,
Yes, you may use the X Series counters to generate a retriggerable finite pulse train.
The X Series manual does mention this capability in the section regarding Counter Triggering (page 7-50😞
For counter output operations, a start trigger can be configured to begin a finite or continuous pulse generation. Once a continuous generation has triggered, the pulses continue to generate until you stop the operation in software. For finite generations, the specified number of pulses is generated and the generation stops unless you use the retriggerable attribute. When you use this attribute, subsequent start triggers cause the generation to restart.
When using a start trigger, the start trigger source is routed to the Counter n Gate signal input of the counter
An example of how to configure this in DAQmx (I'm assuming you are using LabVIEW, but the other APIs are similar) can be found here.
Best Regards,
