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.To meet this specified accuracy when measuring mobile station (MS) or user equipment (UE) within

3 dB of the required −33 dBc ACPR, the mixer level (ML) must be optimized for accuracy. This opti- mum mixer level is −25 dBm, so the input attenuation must be set as close as possible to the average input power − (−25 dBm). For example, if the average input power is −6 dBm, set the attenuation to 19 dB. This specification applies for the normal 3.5 dB peak-to-average ratio of a single code. Note that if the mixer level is set to optimize dynamic range instead of accuracy, accuracy errors are nomi- nally doubled.

c.ACPR accuracy at 3.2 MHz offset is warranted when the input attenuator is set to give an average mixer level of −13 dBm.

d.In order to meet this specified accuracy, the mixer level must be optimized for accuracy when measur-

ing node B Base Transmission Station (BTS) within 3 dB of the required -40 dBc ACPR. This opti- mum mixer level is −23 dBm, so the input attenuation must be set as close as possible to the average input power − (−23 dBm). For example, if the average input power is -5 dBm, set the attenuation to

18 dB. This specification applies for the normal 10 dB peak-to-average ratio (at 0.01% probability) for Test Model 1. Note that, if the mixer level is set to optimize dynamic range instead of accuracy, accu- racy errors are nominally doubled.

e.ACPR accuracy at 3.2 MHz offset is warranted when the input attenuator is set to give an average mixer level of −12 dBm.
