conversion of unratioed measurement values from magnitude to real/imaginary

To Whom It May Concern, 

Thank you for your attention on this post. 

I recently use PNA-X N5245A to measure unratioed values, like A, B, C, D. However, I found the measurement values are correct when we are using magnitude (either linear and nonlinear). But we found the corresponding real/imaginary value is not clearly defined. Would you mind to disclose the conversion formula from their magnitude/phase to real/imaginary. 

And what is actually the measured signal is, the voltage or current?

Best,

Da
