Read file located on Agilent PNA

Hello,

I have acquired the appropriate drivers for the Agilent PNA series Network Analyzers (I'm currently using N5230C and N5222A) and want to check a calibration file already located on the analyzers.  I've been unable to find a decent example of how to find a file already located on the analyzer, read it, and continue.  Can someone shed some light on a way to do this?  Thanks.
