Should I use two port one for the waveguide end and the other at the coax and look at S21? What parameter is critical in determining the accurate performance of the device? Thanks in advance

You would need two ports.simple because of the reason you would like to know the transmission coefficients from the transition. and also you would like to measure the bandwidth over which the transition works efficiently.
