Waveform not smooth and frequency of waveform can't change

[Jason_Chan]

Hi,

I have taken out the loop of the example vi. I can run the program and change the amplitude but i have some problems:

1. When i change the frequency, the frequency of the waveform generated doesn't change.
2. The waveform generated is not smooth. (try to run the program few times)

I have attached the program. Please help me to solve the problem.

Best wishes. Chan

Hello

I can't see your Vi since it's saved in LabVIEW 7.1 version. Look at the LabVIEW examples, many times there you'll find the answers you're looking for. Here is a Vi that I took from there.
