Abstract

Study the phase noise for 126 comb carriers LUT with differenct desiged power level for each carrier.
Check if the IF switch and BB switch used for IF board add any additional noise.

Why

We have confirmed the amplitude and phase noise is related to the total signal power. We want to learn how the noise related to each carrier in the same LUT (which mean the total power is fixed) with different indivicual power.
