98BAND SCOPE (Multi-function receiver/Component screens only)10■ OperationThe band scope function has 2 modes, Frequency and Timemodes.When Frequency mode is selected, the band scope functionsweeps in the specified span from the displayed frequencyand allows you to visually check the received signal strengthon the function display.When Time mode is selected, the band scope function dis-plays the received signal strength in the specified time periodon the function display while sweeping.• When SSB or CW mode is selected, receive audio ismuted while monitoring the band scope.• According to the setting combination of the sweep widthand sweep tuning step, some signals may not be dis-played on the function display during sweeping.• During IC-PCR2500’s dualwatch operation, band scopefunction is available on Main band only.D Using Frequency modeqClick zFREQx to select Frequency mode.• Time mode is selected when zTIMEx is clicked.wClick the sweep start button (z≈x) to begin a sweep; signalconditions appear starting from the center of the range.• Conditions over the entire set frequency span can be observedaround the center frequency of the currently received frequency.• When a strong signal is received, the waveform is indicatedsmall.eClick zSPAN +x or zSPAN –x to select the sweep widththrough SPAN1 (±25.0 kHz) to SPAN5 (±500 kHz).*• Choose SPAN1 when band conditions are crowded (many sig-nals are present); choose SPAN5* when few signals are present.*When the wide band scope function is selected, sweep width ex-pands to SPAN8 (±5 MHz). (p. 103)rClick zYx(TS) or zZx(TS) to select the sweep tuning step.• “LIMIT” appears when a selected sweep tuning step is outsidethe automatic sweep step setting. (p. 86)tClick the waveform to select the frequency of the signal.• Click z❙ ❙x to pause a sweep and monitor the frequency. Repeatto resume the sweep. (“PAUSE” is displayed.)• While pausing the band scope, you can also select the displayedsignal frequency by clicking the waveform.In this case, the selected frequency does not move, and the pre-viously received frequency is kept to center. So you can selectthe previously received frequency simply by clicking a center.yClick the sweep stop button (z‘x) to stop a sweep.D Using Time modeqClick zTIMEx to select Time mode.• Frequency mode is selected when zFREQx is clicked.wClick the sweep start button (z≈x) to begin a sweep; thereceived signal strength is displayed.eClick zTIME +x or zTIME –x to select the time scale for in-dication through 100 min, 30 min, 10 min and 3 min.rClick the sweep stop button (z‘x) to stop a sweep.
