MXA N9020A ACPR - how to offset power?

Question asked by mirek on Oct 1, 2014
How do you set offset to the measured power?
I measure LTE ACPR for 100W power amplifier at 30dBm Pout and I use on the input 35dB external safety attenuator. The problem is that the carrier power show lower value then it should be due to my safety attenuation. I do not see any setting in the Spectrum Analyzer that offset the power in LTE mode. 
If I am in standard Spectrum Analyzer mod you can offset the power in Amplitude setting. That setting is blank if you go to LTE ACPR.   
Any other way to offset the power.

Regards.
