How to generate a 1 millisecond impulse in Labview

[sakshi14]

Hi

I need to generate a 1 millisecond impulse in labview. I tried using the Impulse pattern VI. The minimum number of samples that i can input is 1, which gives me a duration of 1,5 sec approx. Moreover I still don't understand the impulse generation(no frequency input needed?)
Please help me with the generation of very short duration impulses which I then need to transmit through a speaker for some experimentation.
Thanks in advance.

Hi sakshi,

you can generate a millisecond pulse on your DAQ device when you output samples with a samplerate of 1kHz and set one sample to TRUE and all other to FALSE.

So you need to create a waveform specifying your signal and output it with the correct sample rate. That's all…

(Don't get the idea to try this with wait functions. It will not work reliable.)
