Removethe antennafrom the EUT and then connecta low RF cablefrom the antennaport to the spectrum. 2. Set the spectrumanalyzer:RBW= 100kHz.VBW= 300kHz.Sweep= auto;DetectorFunction= Peak. Trace= Max hold. 3. Allowthe traceto stabilize.It may provenecessaryto breakthe spanup to sections.in orderto clearly showall of the hoppingfrequencies.The limit is specifiedin one of the subparagraphsofthis Section. 4.
