(1) A 185-MHz, full-scale, sine-wave input signal is applied to all four channels.

(2) There are two sources of gain error: internal reference inaccuracy and channel gain error.

(3) Phase and amplitude imbalances onboard must be minimized to obtain good performance.

(4) The minimum value across temperature is ensured by bench characterization.
