How to get the sparameter trace output from N9917A

I'm using a N9917A Agilent's Network Analyzer. I have difficulty in getting the output from the analyzer.

I have interfaced the Analyzer with the pc as given in the following link ( http://in.mathworks.com/help/instrument/examples/characterizing-a-low-noise-amplifier-by-measuring-its-s-parameters.html )

The diffculty comes when I want to get the output from the Analyzer as a .csv file. I'm working on a DUT with a sensor connected to the VNA.

I'm measuring s parameters. I need to get the s-parameter traces once every 10 seconds and the minimum values of the trace for each position should be obtained.

And the file format should be in a .csv format. I dont know to get the exact SCPI command for getting the exact file format.

Please help. Thanks.
