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.
b. Accuracy is specified without NC. NC will make the accuracy even better.
c. The Fast method has a slight decrease in accuracy in only one case: for BTS measurements at 5 MHz
offset, the accuracy degrades by
±0.01 dB relative to the accuracy shown in this table.
