Vane Attenuator and VSWR

Folks,

  We've been looking at different methods calibrating this device.  More specifically determining VSWR for this device, the first method
utilizes a SWR bridge, the next method utilzes a scalar analyzer.  Both these methods uses a ratio method.  The SWR method takes the squareroot of the ratio Vmax and Vmin. 
The scalar analyzer method takes SWR and divides it by the input signal (R/A).  How would I do it on a E8364B VNA?  Are all these different methods equivalent?
