Specifications

Dynamic range
The dynamic range required to test the AUT is the difference, in decibels, between
maximum boresite level and minimum AUT level that must be measured. Examples of
these include side-lobe level, null depth, and cross-polarization levels.
Measurement accuracy/signal-to-noise ratio
Measurement accuracy is affected by the measurement sensitivity of the system. The
signal-to-noise ratio will directly impact the measurement accuracy of the system for
both amplitude and phase measurements. Figure 15 illustrates the relationship between
signal-to-noise ratio and magnitude and phase errors.

Determine your signal-to-noise ratio based on the magnitude and phase errors you
can accept.
