S parameters with 8722A Network Analyzer issue

I am trying to get an .s2p file from my network Analyzer (HP 8722A) using LabVIEW and GPIB communication.
I first send "S11" then "FORM4" to specify the format to be in ASCII, then "OUTPFORM" at which point I read the data back.
I get a table with 2 columns.
It seems that the dB values (left column) are correct, but the frequency list consistently remains 0.
What am I doing wrong?

Also, is there a simpler way to get the .s2p file?
I went through all the SCPI commands of the 8722A and could not find one that would get this done.

Thank you very much for your help,
