define signal range

Hi, 

1. How to smooth this signal? 

  Sample Module(myDAQ) -> Calculation Module -> output

Calculation module input is: 1 data point, output 1 data point,

we tried to implement low pass fileter in calculation module, but it said, 0<fs_low<fs_high<fs/2.

Can anyone look at the signal file, and give us some suggestions?

2. We use labVIEW to capture a sample data, and want to import to "Arbitrary Signal" module, however, after I load data, "Define signal" window freezed. 

Sample file has 5915 data points, will this out of range?

I attached the sample data file and screen shot of freezed window.

Forum doesn't allow me to upload .lvm file, so I changed its extension to .txt.

Thanks
