DAQ Pulses on LabVIEW Graph/Chart

[SRAZA]

Dear all

I am happy that i am getting required pulse with your guidanc and Help. Now i want to varry the pusle amplitue . Is it possible with current code?

Thanking you in advance.

Hello SRAZA,

I'm not aware of any instances where it is possible to vary the pulse amplitude programmatically in LabVIEW. However, you could possibly vary the voltage level of the counter output with external circuitry. 

Another option you could look into would be generating a square wave from the analog output instead of using the counter output and varying the amplitude of the square wave.

Also, for good programming practice with DAQ, outside of your while loop you should stop the task before you clear it.

Thanks for your suggession . 

 Will i be able to generate 9852 frequency from analog IO card? I have PXI 6704 with 16 AO .

Hello SRAZA,

Have you tried using DAQmx Timing and setting the rate?
