PXIe-5413-finite number of pulses-question

 

Hello all, 

 

I have a question regarding PXIe-5413 card (with one output).

I have looked on the drivers and examples from library but I do not understand if it is possible to output a finite number o pulses for example, triggered by software.

I do not see in the drivers "Burst" or Pulse function.

For example I want to output 3 square pulses with 2 second delay between them when I use software trigger( activated by a button on front panel).

 

Thanks in advance!

Aflorin,

 

That would likely be achievable with arbitrary waveform mode.

 

What is the pulse width (e.g. in milliseconds) you are looking for?

Hello Balexand, 

 

In the past I have worked with Keysight and Agilent. With this external instruments, I have found special functions in their drivers that let me to generate pulses with settable time and number without need to use arbitrary waveform mode.

With this pxie-5413 I see is not possible to choose this settings. 

 

I am not aiming to a precise with and number of pulses, and I want to let the user to choose.

I am asking this, maybe is something that I have not seen in the drivers.

I do not want to use arbitrary waveform mode in my setup because things will be more complicated for the final user.

Also I have attached 2 pictures from Keysight driver to be more clear about this setup. Also I use delacor tool(with classes) and I want to create a setup user friendly and I must integrate this pxie board and the child functions to be similar with Keysight and Agilent external instruments. If I use arbitrary waveform I do not think I will manage to have same setups for all the instruments.

 

Thanks for fast replay!

The NI-FGEN driver API doesn't expose those generation modes directly.  What I was suggesting is that such a programming interface could likely be implemented as a software layer on top of NI-FGEN.  Then you could have the simple Pulse or Burst interface that you need, and the fact that it uses arbitrary waveform mode under-the-hood is just an implementation detail.

Hello Balexand, 

 

I understand and you are right. Do you have any example with arbitrary waveform mode?

 

Thanks!
