4.1.3 Trace AverageTaking the average is the digital processing. It is to plus current value in each tracepoint and previous average value, and then take the average. Choose the operationof taking average. When spectrum analyzer is doing the automatic coupling, it canmake the displayed noise level get smooth to change detection mode into samplingmode.1) Reset spectrum analyzer2) Set the frequency of signal source and amplitude as 1 GHz and -80 dBm.Connect the RF OUT port of signal source to the RF IN port of spectrumanalyzer and turn on the signal output.3) Set center frequency, span and reference level: Press FREQ ĺ 1GHz Press SPAN ĺ 5MHz Press AMPTĺ - 40dBm4) Press TRACE ĺAverage (ON) to turn on the average function. Press 100 ĺ ENTER, set the number of average as 100. Because theoperation of taking the average will make the trace be smooth, and the lowlevel signal will be clearer.
