New Features  新功能

Purge feature  清除特性

Due to the high resolution and sensitivity of the AQ6376E, it can actually detect the presence of water molecules in the air. The water vapor is detected in the upper Near-IR wavelength region and could overlap with or mask the spectral characteristics of the actual device under test in that particular region.
由于 AQ6376E 分辨率高且靈敏，它實際上可以檢測空氣中的水分子。水蒸氣在高頻近紅外波長區(qū)域被探測，可能與被測器件在該特定區(qū)域的光譜特性重疊或掩蓋。

By continuously supplying a pure purge gas such as nitrogen to the monochromator through the ports on the back panel, the AQ6376E can reduce the influence of water vapor absorptions and provide more reliable and accurate measurements than ever before.
通過通過背板端口持續(xù)向單色器供應(yīng)純凈凈化氣體如氮氣，AQ6376E 可以減少水蒸氣吸收的影響，提供比以往更可靠、更準(zhǔn)確的測量。

Built-in cut filter for high order diffracted light
內(nèi)置高階衍射光切割濾鏡

Due to the diffractive technology used, the monochromator in some circumstances could generate high order diffracted light, which appears at wavelengths equal to the integral multiple of input wavelengths.
由于所使用的衍射技術(shù)，單色儀在某些情況下可以產(chǎn)生高階衍射光，這些光出現(xiàn)在等于輸入波長整數(shù)倍的波長上。

By cutting incoming light below 1500 nm with the built-in filter, the AQ6376E drastically reduces the influence of high order diffracted light on the measurement. Thus, the measured data are always reliable and replicate the real signal under test.
通過內(nèi)置濾光片切割 1500 納米以下的入射光，AQ6376E 大大減少了高階衍射光對測量的影響。因此，測量數(shù)據(jù)始終可靠，并能復(fù)制被測的真實信號。

Double speed mode  雙速模式

Increases the sweep speed up to 2 times compared to the standard sweep mode, with only a 2 dB penalty to the standard sensitivity value.
相比標(biāo)準(zhǔn)掃頻模式，掃描速度可提升最多 2 倍，且僅對標(biāo)準(zhǔn)靈敏度值增加 2 dB。

Long Wavelength Range: from 1500nm to 3400nm
長波長范圍：1500nm 至 3400nm

The AQ6376E covers not only the wavelength span used in communications, but also the 3µm region which is used for environmental sensing, medical, biology and industrial applications.
該 AQ6376E 不僅涵蓋通信中使用的波長范圍，還涵蓋了用于環(huán)境感測、醫(yī)療、生物學(xué)和工業(yè)應(yīng)用的 3μm 區(qū)域。

High Sensitivity: down to -65dBm
高靈敏度：低至-65dBm

The AQ6376E can measure optical power from +13dBm down to -65dBm thanks to its high-dynamic and very low noise components and circuits used for photo detection. This enables precise measurements of both high power and low power sources.
該 AQ6376E 得益于其高動態(tài)且極低噪聲的成分和用于光檢測的電路，能夠測量從+13dBm 到-65dBm 的光功率。這使得能夠精確測量高功率和低功率源。

Measurement sensitivity can be chosen among 7 values according to the measurement speed required by the specific test to be performed.
測量靈敏度可以根據(jù)具體測試所需的測量速度從7個數(shù)值中選擇。

High Resolution & Wide Dynamic Range
高分辨率與寬動態(tài)范圍

The AQ6376E uses a double-pass monochromator structure to achieve high wavelength resolution (0.1 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.
該 AQ6376E 采用雙通單色器結(jié)構(gòu)，實現(xiàn)高波長分辨率（0.1 nm）和寬的近距離動態(tài)范圍（55 dB）。因此，緊密分配的信號和噪聲可以分別測量。
