A VNA gives you serial or parallel equivalent R or X ( C or L ) values at certain frequency.When you divide X value ( 2xPIxF or 1/2xPIxF ) you'll get L or C values respectively.
For instance, let say you have read 0.55+j*0.77 Ohm ( normalized ) impedance on your VNA @ 2GHz.It's a serial R+j*XL impedance.
Z=50*(0.55+j0.77)=27.5+j*38.5 @2GHz
So R=27.5 Ohm, L=3.06nH
If you need parallel equivalent, transform it to serial to parallel...
I hope I understood your question well...
