Help file for the Plug and Play driver of Agilent Technologies E5071C

I just download the Plug and Play driver of Agilent Technologies E5071C from the below link:
http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=5692
I find that there is only some examples and not any help file with detail description for each input of those VIs. Although there is brief description for each VI when I press "Ctrl+H" on the VI,I still can't figure out how to use this driver. :-(
Is there any help files with more detail description?
Or any related examples for my reference? I hope to measure the S11 and S21 of the SMA cables
