generating trigger using a counter

[RaphaelCotty]

Hi,

I am wondering if it's possible to use a counter input to generate a trigger signal with one of the NI PCI boards.

Thanks

Hi Raphael,

What PCI card are you using?  Can you tell me a bit more about what you are trying to do?  In the example finder found in the Getting Started window when when labVIEW opens or in the help tab from within a labVIEW VI.  There is some good examples found under Hardware Input and Output > DAQmx then depending on what you want to do look under the relevant folder. 

Regards

Hi,

I am using a NI USB-6211 and plan to use a PCI equivalent.

My application needs to average pulses of data. I am using an acqiris averager for this.

I would also like to use the trigger of the pulses to generate every n times another trigger.

This trigger would be used to generate a clock for buffer position measurements of an angular encoder (using a NI DAQ).

That will allow me to synch the average of the pulses with the angular reading.

I am wondering if any NI device would allow me to do it (and the angular encoder reading as well).

Hope this clarify a bit the context.

Thanks

Hi Raphael

The PCI cards NationaI Instruments offer will be able to achive this task.  Did you look at the examples I suggested you look at? They show how it can be achived using the DAQmx VI's 

Hope this helps

Hi Raphael,

You can achieve this using frequency division feature (pulse train generation) of the card. This feature allows to generate the pulse with frequency that is a fraction of an input signal (see documentation to NI 6010 card, for example). This generated pulse then can be used as an input for trigger.
