N5227A Noise Figure Opt 028

Hi all,

I am currently using NS 346CK01 and PXA N9030A with preamp of gain >27db and NF <6db for noise figure measurement. Prior to this measurement, i did S Parameter and Gain Compression measurement using PNA N5227A.

If i were to use PNA opt 028 for noise figure measurement, what would be changes to the calibration.

I am using Ecal N4694-60003 for my 2 port cal. Can that Ecal be use for NF cal? 

Will switching from Y factor method (PXA with NS) to Cold method (PNA) results in a more accurate measurement? 

What other steps be taken to further improve accuracy of NF measurement using PNA? 

All the questions focus on Opt 028 only. 

Thank you
