filter pxi-6602 LabVIEW DAQ-mx

Hi,

 

I have a PXI-6602 card.

The signal to measure is on the gate pin.

On the source pin, it is the internal 20MHz.

The counter uses the ND_BUFFERED_EVENT_CNT mode.

I have a LabWindows code with NI driver DAQ for this card which uses filter with this function <<< Line_Change_Attribute( device number, line name, ND_LINE_FILTER, ND_5_MICROSECONDS) >>>

 

I must rewrite the code to LabVIEW with NI driver DAQ-mx.

I use the counter to count edge mode.

I don't know how to configure the same filter in LabVIEW with DAQ-mx.

 

Can you help me ?

thanks

 

best regards

Assuming you're using the external signal as a "sample clock" in your edge count task, you would enable the filter like this (called before starting the task):

There are other ways to configure what is essentially the same thing though--if you're using the external signal as something other than a sample clock (e.g. a "pause trigger") then there would be a different property that you would need to set instead.
