NI DAQ 6281 Programmable Low Pass Filter r feature

[AutomationUET]

Dear Sir

I am using NI DAQ 6281 M-series. In device mannual I read that it has programmable low pass filter to remove the noise and to prevent antialiasing. But when I connect DAQ card with my PC and check in LabVIEW, no low pass filter option appears. Only I can set incoming signal range, connection mode, sampling rate, number of samples and acquisition mode.

Can you please guide me how I can set the low pass filter. I need to set low pass filter at 4 KHz.

Best Regards

Automata,

you have to use channel property nodes to enable and configure the lowpass filter on the 6281.

Dear Sir

I have found channel property node and select the low pass filter. But can you please guide me how I can read data from the analog input port of DAQ using this property channel and after filteration make plot.

My Block diagram is attached.

Automata,

you cannot use that property for tasks you encapsulate in the DAQ assistant.

You can create code from your DAQ assistant (right click >> Generate DAQmx Code) and the add the properties to the task before starting it.

PS: Your loop wastes a lot of space....please make it a little smaller so it fits on a screen....
