频谱显示操作Scope Operation
本章介绍 IC-7300 的频谱显示功能：SPECTRUM SCOPE 屏幕可实时显示所选波段上的信号活动及各信号的相对强度，支持 CENTER（中心）、FIX（固定）与 SCROLL（滚动）三种模式，并可开关瀑布图（Waterfall）显示。内容涵盖频谱屏幕的按键与触摸操作（点触信号即可直接 QSY）、基准电平与扫描速度的调整、SCOPE SET 屏幕的各项设置（发射时显示、峰值保持、中心频率类型、波形颜色、瀑布图尺寸与固定边界等），以及显示音频频谱与波形的 AUDIO SCOPE 屏幕。
This chapter describes the Scope function of the IC-7300: the SPECTRUM SCOPE screen displays the activity on the selected band and the relative strengths of various signals in real time, with Center, Fixed and Scroll modes and an optional Waterfall display. It covers the key and touch screen operations of the spectrum scope (touch a signal to directly QSY to it), adjusting the Reference level and the sweep speed, the SCOPE SET screen items such as the TX signal display, peak hold, center frequency type, waveform colors, Waterfall size and Fixed Edges, and the AUDIO SCOPE screen that displays the audio spectrum and waveform.
5-2频谱显示屏Spectrum scope screen
该频谱显示可用来显示所选波段上的信号活动情况以及各信号的相对强度。IC-7300 有两种频谱显示模式：一种是 CENTER（中心）模式，另一种是 FIX（固定）模式。还可以开启或关闭瀑布图（Waterfall）显示。此外，还可选择迷你频谱屏（Mini scope screen）以节省屏幕空间。
This spectrum scope enables you to display the activity on the selected band, as well as the relative strengths of various signals. The IC-7300 has two spectrum scope modes. One is the Center mode, and another one is the Fixed mode. You can also turn the Waterfall display ON or OFF. In addition, you can select a Mini scope screen to save screen space.

标记Marker
标记（Marker）用于在 SPECTRUM SCOPE 屏幕上指示工作频率。
The Marker displays the operating frequency in the SPECTRUM SCOPE screen.
• 关于 RX 标记：在 Fixed 模式与 Scroll 模式下，RX 标记在指定频率范围内指示工作频率，因此收发信机在频谱屏幕中始终显示 RX 标记。在 Center 模式下，工作频率保持在屏幕中心，因此收发信机不显示 RX 标记。当 Hold 功能开启时，会显示 RX 标记以指示工作频率的位置。
• About RX Marker: In the Fixed mode and the Scroll mode, the RX Marker displays the operating frequency within a specified frequency range. So, the transceiver always displays the RX marker in the scope screen. In the Center mode, the operating frequency stays on the Center of the screen. Thus, the transceiver does not display the RX Marker. When the Hold function is ON, the RX Marker is displayed to indicate the operating frequency's location.
