Too many data points

[larsonn4]

I am new to Signal Express and need to use it to record data from 2 DAQ units.  I have been able to see the graphs in real time and to record, but when I export the data to Excel, there are too many data points.  For a 30 second record time I get thousands and thousands of points.  Excel can only graph 3200 at a time.

How do I reduce the sampling rate?

Hi larsonn4,

You can reduce the sample rate by changing the Samples to Read and the Rate (Hz) as shown in the included screen shot.  The rate is the acquisition rate and the samples to read are the samples read off the buffer each time.
