Measurement of Re Measurement of Re Measurement of Re Measurement of Receiving Level from Base Station ceiving Level from Base Station ceiving Level from Base Station ceiving Level from Base Station ( For trained
personnel)
1) Connect feeding cable, which has been connected to the outdoor antenna for
base station, with input of spectrum analyzer.
2) Set measurement environment of Frequency, Span, BW and Amplitude, etc of
the spectrum analyzer.
3) Verify Channel Power value of input signal.
