high power amplifier testing using PNA

Hi Groups,

 

I am studying the app. note "recommendations for testing high power amplifiers using the pna microwave analyzers".

For the p.22, I don't understand how comes the source provides -42~13dBm but it becomes -40~-12dBm after the 20dB source attenuation ?

Looks like the source attenuation does not affect the power level ?

 

Thanks.
