Dear Sir:
I use the PSA at the spectrum mode under 1GHz and measure the minimum noise floor power. I discover that the linear average and log average noise power is different.
The value will be different 2~3dB.
Is any spectrum setting in my site is incorrect?
Thank you.

The problem is explained well in application note 150:
