The setup used to evaluate baseband frequency sweep and
undesired sideband nulling of the ADL5374 is shown in Figure 40.
The interface board has circuitry that converts the single-ended
I input and Q input from the arbitrary function generator to
differential I and Q baseband signals with a dc bias of 500 mV.

Undesired sideband nulling was achieved through an iterative
process of adjusting amplitude and phase on the Q-channel. See
the Sideband Suppression Optimization section for a detailed
discussion on sideband nulling.
