N5234A How to get SnP data?

Dear all,

I'm using Labview 12 to remote control the Agilent N5234a VNA. I want to get the S parameters include “S11, S12, S21, S22”. In the labview program I use the instrument I/O assistant to control the N5234a. The code sequences are: 

  The 1st line, select the N5234a VNA. 

  The 2nd line,
     command: Query and Parse,  code: *IDN?
     there is no error and some information about the N5234a are returned.

  The 3rd line, 
     command: Write,   code: calc:par:sel "CH1_S11_1"
     there is no error. After this command, if I use the command of "calc:par:sel? ", it returns "CH1_S11_1", which show the 3rd line code is executed rightly.

  The 4th line: 
    command: Query and Parse,  code: calc:data:snp:ports? "1,2"
    there is no response in I/O assistant. An error of "Query INTERRUPTED (-410)" occurs on the N5234a screen.  
 
   So, how to modify my command sequences to obtain the S parameters?

   By the way, if the code of the 4th line is replaced with: 
calc:data:snp:ports:save "1,2","d:\test.s2p";*OPC?
   I find the test.s2p file is stored in the N54234a VNA, but not in my local computer! So, how to store the SnP file in my local computer?

Thanks.
