Shape Factor of N5222A For PS to PSD Conversion

Hi,

 

I am making some dBm/Hz measurements with a 1kHz IFBW with an N5222A VNA over a 26.5GHz bandwidth.

 

I need to convert from dBm to dBm/Hz so to do that I need to know the IFBW and the Shape Factor  (I don't know what keysight calls it).

 

So dBm/Hz = (Measured dBm) / (IFBW*SF)

 

Can someone tell me what this SF value is typical or how I can measure it? References to white papers or Dr. Joel's book are fine.

 

Thanks.
