計(jì)算指定帶寬中的功率譜密度，并將結(jié)果寫(xiě)入
跟蹤F。
目標(biāo)記錄道是從記錄道a到E中選擇的單個(gè)記錄道。
您可以以0.1 nm的步長(zhǎng)將帶寬設(shè)置在0.1 nm到10 nm的范圍內(nèi)。跟蹤
數(shù)據(jù)區(qū)側(cè)面顯示“PWR/NBW@”。
標(biāo)記器功能<<有關(guān)操作程序，請(qǐng)參見(jiàn)第6.9節(jié)>>
標(biāo)記函數(shù)可用于輕松測(cè)量波長(zhǎng)差異和電平
差異，并搜索峰值波長(zhǎng)、峰值水平和光譜寬度。
有標(biāo)記、線標(biāo)記和標(biāo)記。
標(biāo)記
共提供1025個(gè)標(biāo)記（一個(gè)移動(dòng)標(biāo)記和1024個(gè)固定標(biāo)記）。
使用旋轉(zhuǎn)旋鈕箭頭可以將移動(dòng)標(biāo)記移動(dòng)到任意波長(zhǎng)
鍵或數(shù)字鍵盤(pán)。也可以用鼠標(biāo)拖動(dòng)標(biāo)記。移動(dòng)
標(biāo)記可以在波形上移動(dòng)以顯示標(biāo)記值（波長(zhǎng)
和級(jí)別值）。如果移動(dòng)標(biāo)記固定在任意位置，則
更改固定標(biāo)記。
固定標(biāo)記是固定到設(shè)置移動(dòng)標(biāo)記的數(shù)字的標(biāo)記。固定的
標(biāo)記從001開(kāi)始按順序分配標(biāo)記編號(hào)。您可以輸入
使用旋轉(zhuǎn)手柄、箭頭鍵或數(shù)字鍵盤(pán)輸入任意數(shù)字。多為的數(shù)字
可設(shè)置1024。設(shè)置多個(gè)固定標(biāo)記時(shí)，可以顯示波長(zhǎng)
給定標(biāo)記和相鄰標(biāo)記之間的差異和水平差異。
Computes the power spectral density in the specified bandwidth and writes the results in Trace F. The target trace is a single trace selected from Traces A to E. You can set the bandwidth in the range from 0.1 nm to 10 nm in 0.1 nm steps. The trace display at the side of the data area shows "PWR/NBW @". Marker Functions > Marker functions can be used to easily measure wavelength differences and level differences, and to search for peak wavelengths, peak levels, and spectrum widths. There are markers, line markers, and advanced markers. Markers A total of 1025 markers (one moving marker and 1024 fixed markers) are provided. Moving markers can be moved to an arbitrary wavelength using the rotary knob, arrow keys, or numeric key pad. You can also drag the markers with the mouse. Moving markers can be moved over a waveform to display the marker values (wavelength and level value) in the data area. If a moving marker is fixed in an arbitrary position, it changes to a fixed marker. Fixed markers are markers fixed to a number on which the moving marker was set. Fixed markers are assigned marker numbers in order starting from 001. You can enter an arbitrary number using the rotary knob, arrow keys, or numeric key pad. A number up to 1024 can be set. When multiple fixed markers are set, it is possible to display wavelength differences and level differences between a given marker and adjacent markers.
