Cellular Base Station Power Testing Requirements
Testing and monitoring the RF performance of wireless communications systems is becoming extremely important for new base station installations. You can use a handheld spectrum analyzer to test RF power; however, the tool may not be useful for power measurements that require accuracy better than 0.7 dB. What are your power accuracy requirements? Do you need to measure the average power only, or are other measurements -- such as peak power, burst power, peak to average ratio, etc. -- also required?
