Pulse Width Measurement

[Dennis_Knutson]

What is the point of that image? Do you get the same signal in MAX and LabVIEW? If you do, what happens when you pass the signal to the pulse width code you have?

A DAQ task can be configured for multi-channel acquisition and set to return a 1D waveform array. This can be passed to a for loop that has the measurement code inside and it would return an array of calculated pulse widths for each channel.

The image is coming from an Zero crossing detector circuit. It gives a pulse every times Ac voltage crosses zero. And the 1st pulse width is smaller because the circuit was switched at maximum voltage. Here is a better picture.

I get the same signal from MAX. But I am struggling to use it in the pulse width code.

Can you maybe help me to get in my pulse code where I can get the signal from outside to the input of hardware. Or as you said corfiguring for multi-channel. 

Can you help me with that ?

Stop posting images from that hardware and start posting images of your LabVIEW acquisition code. There are several shipping examples of analog acquisition using DAQmx. If you can acquire the signal in MAX, you can acquire it in LabVIEW.

Here is the VI.

But here the signal is generated from VI itseft.

Can you help me to get signal from outside. So i can put signal on my input channels.

Kind Regards,

As I said, open the DAQmx examples. At the most basic level, create a new VI and drop a DAQ Assistant on the block diagram.

Can someone help me with the error in connection.

Thanks.
