Re : TTL signal Production

[DKLabView]

hi.. I am using DAQ 6216. I want to generate a TTL pulse with 1ms on time and 10ms off time

[JB]

As mentionned here : LV menu >> Help >> Find Examples... >> Hardware Input and Output >> DAQmx >> Counter Output

Doesn't this help ?

Hi thanks for reply ..

 i cudnt find any such example in the help

 I had able to make a vi  using DAQ assistant for the same. But  want to make one without DAQ assistant function .. for more flexible output

Thanks

So just convert the VI from the DAQ Assistant and adapt it to your needs. The conversion is straightforward :

1. Right-click on the VI
2. Select Generate NI-DAQmx code (uncertain translation from french DAQmx, second to last entry of the contextual menu).

Hi..

Thanks for reply...

While using this vi , on DAQ output I am getting almost 6ms ON time and 15 ms OFF time (on Oscilloscope).

How to use a signal generator function to give input

What do you want to do exactly ? A function generator with variable frequency, duty cycle... ? Anything else ?
