Set analyzer center frequency to DTS channel center frequency. RBW=3kHz, VBW3RBW, Span=1.5 times DTS bandwidth, Detector=Peak, Sweep=auto, Trace= max hold. 2. Allow trace to fully stabilize, use the peak marker function to determine the maximum amplitude level within the RBW. 3. Repeat above procedures until other frequencies measured were completed.
