•WDM分析•EDFA-NF（光放大器增益，NF测量）•功率分析•DFB-LD分析的OSNR和总功率•FP-LD分析的总功率•LED分析的总功率•功率谱密度标记，集成功率标记自动测量>此功能自动设置输入光的佳测量条件并显示光谱波形。当输入光的特性未知时，此功能非常有用。可自动测量的输入光波长范围为1200–1670 nm。自动设置的测量条件如下所示。1、跨度（Span）2。中心波长（中心）3。参考等级（参考等级）4。分辨率（Resolution）其他测量条件（灵敏度、平均时间、采样点数量和间隔设置）设置为其默认值。显示的频谱波形的水平轴和垂直轴被缩放到适当的程度。Single Sweep>此函数执行单个扫描或强制停止扫描操作。

• WDM analysis • EDFA-NF (optical amp gain, NF measurement) • Power analysis • OSNR and total power of DFB-LD analysis • Total power of FP-LD analysis • Total power of LED analysis • Power spectral density markers, Integrated power markers Auto Measurement > This function automatically sets the optimal measuring conditions for the input light and displays the spectrum waveform. This function is useful when the characteristics of the input light are not well known. The wavelength range of input light that can be auto-measured is 1200–1670 nm. The measurement conditions that are set automatically are as follows. 1. Span (SPAN) 2. Center wavelength (CENTER) 3. Reference level (REF LEVEL) 4. Resolution (RESOLUTION) Other measuring conditions (sensitivity, averaging times, number of sampling points, and interval settings) are set to their defaults. The horizontal and vertical axes of the displayed spectrum waveform are zoomed to an appropriate degree. Single Sweep > This function executes a single sweep or forcibly stops a sweep operation.
