5-2■ Spectrum scope screen This DSP-based spectrum scope allows you to displaythe conditions on the selected band, as well as relativestrengths of signals. The IC-R9500 has two modes forthe spectrum indication— one is center mode, and an-ther one is fixed mode.In addition, the IC-R9500 has a mini-scope screen tosave screen space.DD Center modeDisplays signals around the set frequency within theselected span. The set frequency is always displayedat the center of the screen.q Push [EXIT/SET] several times to close a multi-function screen, if necessary.w Push [F-1•SCOPE] to select the scope screen.• The spectrum scope shows the peak level holding func-tion. Peak levels are displayed in the background of thecurrent spectrum in a different color until the receive fre-quency changes. This can be deactivated and the wave-form color can be set in scope set mode. (p. 5-7)e Push [F-6•CENT/FIX] to select the center mode.• “ ” is displayed when center mode is selected.r Push [F-2•SPAN] once.• Multifunction switch guide changes to the span settingguide.t Push [SPAN+] or [SPAN–] several times to selectthe scope span.• ±2.5 k, ±5.0 k, ±10 k, ±25 k, ±50 k, ±100 k, ±250 k,±500 k, ±1 M, ±2.5 M and ±5 MHz are available.y Push [F-3•BW/SPEED] once.• Multifunction switch guide changes to the resolutionband width/speed setting guide.u Push [BW+] or [BW–] several times to select theresolution band width.• 0.2 k, 0.5 k, 1 k, 2 k, 5 k, 10 k and 20 kHz are available.i Push [SPEED–] or [SPEED+] several times to se-lect the sweep speed.o Push [F-4•ATT] several times to activate an attenu-ator or turn the attenuator OFF.• 10, 20 and 30 dB attenuators are available.!0 Push [F-5•HOLD] to freeze the current spectrumwaveform.• “ ” appears while the function is in use.• The peak hold function can be deactivated in scope setmode.!1 Push [EXIT/SET] to exit the scope screen.NOTE: If a strong signal is received, a ghost wave-form may appear. Push [F-4•ATT] several times toactivate the spectrum scope attenuator in this case.Spurious signal waveforms may be displayed if gen-erated in the internal scope circuit and do not indi-cate a receiver malfunction.HOLDCENTER[EXIT/SET][F-5][F-3][F-2][F-1][F-6][F-5][F-3][F-2][F-1] [F-6][F-4] [F-7]SPAN BW/SPEED CENT/FIX PEAKSETMENU1 ATT HOLDW-BPFMENU25 RECEIVE FUNCTIONS• Observed indication example
