Hi Simon,

Please have a look at this page:

Hi Andi,

It works very well, thank you very much.

there is a further insurmountable difficulty, could you please help me.

Please refer to the attached program,after acquired over 1000  pulses of each channel of the sensor output,I have to calculate  width of each pulse using  a while loop structure.but PC run speed is very very slowly,could you please tell me how to speed up the while loop.

Regards,

Simon

Hello Simon,

the only way to speed the while-loop up, is to exchange the property node with a local variable. Though I can't understand what you are doing in the while-loop, you wrote in your last post something about pulse width, I think that the VI "Pulse Measurements.vi", which you are already using, should do the thing. Have you looked into the help to this vi?
