ACPR Accuracy
a
a. The accuracy of the Adjacent Channel Power Ratio will depend on the mixer drive level and whether
the distortion products from the analyzer are coherent with those in the UUT. These specifications
apply even in the worst case condition of coherent analyzer and UUT distortion products. For ACPR
levels other than those in this specifications table, the optimum mixer drive level for accuracy is
approximately −37 dBm − (ACPR/3), where the ACPR is given in (negative) decibels.
