Trigger 2 AO signal synchronously from a fire PFI

Hi all,

 

sorry for being redundant with my old post but i did not get a solution to my problem.

I have a NI PCI 6733 card. I get a signal (start and pause) from the fire ouput of a camera, the duration of the pulse signal is equal to the exposure time of the camera. This signal is connected to the PFI and must trigger SYNCHRONOUSLY two AO Voltage signal: the first one is a triangle signal which must do 2 periods during the exposure time, the second signal must be 5V during the duration of the pulse and 0 after.

I have manage to implement the tirangle signal but i do not manage to insert the 2nd signal. Someone told me to use a square waveform with the same frequency of the triangle signal but why I have to generate a waveform when the 2nd signal is just waiting for 2 values: 5V to be ON and 0V to be OFF. Maybe there is something that I do not understand.

Please help me

thanks

Hello,

 

The function square waveform generates a high pulse and then a low pulse. Moreover, you can specify how long is the high state with the pulse width and the frequency of the function. By using this function, you don't have to implement a piece of diagram, only using a function. Moreover, you already use a function which generates a waveform and you can synchronize your functions both. So why using something different?
