The Span setting selects the number of channels to display on the measurement screen (graph). The channel (when 1CH is selected in Span) is the channel that was selected in the Frequency/Level menu (refer to section “Frequency & Reference Level Configurations” and to Step 2 and substep Step b). You can use that menu to change the channel number. When multiple channels are displayed (by using the Span setting), the channel number that is selected in the Frequency/Level menu is displayed as the center channel.
The channel number, the channel frequency, and the power level are displayed in green in the graph. The frequency and power level at the blue diamond marker are displayed in blue in the graph. The blue diamond marker always denotes the peak level within the green zone.
