单动键<<操作程序见第5.4至5.6节>>
这是使用活动跟踪波形（以下简称
当前显示的波形）来设置测量条件。
设置条件要求显示激活记录道的波形。
一个操作密钥名称描述
峰值→ REF LEVEL将活动记录道测量波形的峰值设置为
参考标高。
标记器→ 参考标高将移动标记标高设置为参考标高。
峰值→中心设置活动记录道的峰值波长或峰值频率
测量波形到中心波长或中心频率。
平均WL→中心设置阈值3 dB中心波长或中心频率
主动跟踪测量波形到中心波长或中心
频率
查看→MEAS将当前显示的缩放比例设置为测量比例
（居中、开始、停止、跨距）进行下一次扫描。
标记器→中心将移动标记的波长设置为中心波长或
中心频率。
Δλ→SPAN将扫描宽度设置为RMS 20 dB宽度的六倍
主动跟踪测量波形。
MKR L1-L2→“跨距”设置扫掠宽度的线标记1和2之间的间距。
峰值→ZOOM CTR设置活动轨迹测量的峰值波长
波形到缩放显示的中心波长或中心频率。
标记器→ZOOM CTR将移动标记的波长设置为中心波长或
缩放显示的中心频率。
MKR L1-L2→缩放范围为缩放的扫描宽度设置线标记1和2之间的间距

One-Action Keys > This is the general name for a key that uses data from the active trace waveform (the currently displayed waveform) to set measurement conditions. Setting conditions requires that a waveform is displayed for the active trace. One-Action Key Name Description PEAK → REF LEVEL Sets the peak level of the measured waveform of the active trace as the reference level. MARKER→ REF LEVEL Sets the moving marker level as the reference level. PEAK→CENTER Sets the peak wavelength or the peak frequency of the active trace measurement waveform to center wavelength or center frequency. MEAN WL→CENTER Sets THRESH 3 dB center wavelength or center frequency of the active trace measured waveform to center wavelength or center frequency. VIEW→MEAS Sets the currently displayed ZOOM scale as the measurement scale (CENTER, START, STOP, SPAN) for the next sweep. MARKER →CENTER Sets the wavelength of the moving marker to center wavelength or center frequency. Δλ→SPAN Sets the sweep width as six times the RMS 20 dB width of the active trace measurement waveform. MKR L1-L2 →SPAN Sets spacing between line markers 1 and 2 for sweep width. PEAK→ZOOM CTR Sets the peak wavelength of the active trace measurement waveform to center wavelength or center frequency of zoom display. MARKER →ZOOM CTR Sets the wavelength of the moving marker to center wavelength or center frequency of zoom display. MKR L1-L2 →ZOOM SPAN Sets spacing between line markers 1 and 2 for sweep width of zoom display.
