Ando AQ6315E光谱分析仪
The AQ6315E optical spectrum analyzer (OSA) is an improved version of 
the well known Ando AQ6315A. This OSA can do spectrally resolved 
intensity measurements in the range of 350 to 1750 nm with a wavelength 
accuracy better than 0.05 nm and supports single-pass/double-pass 
monochromator mode select. In the single-pass monochromator mode, it 
supports the same wide range of applications as previous models. In the 
double-pass monochromator mode, the dynamic range is improved to 
-90dBm. The system is sensitive enough to measure light intensities as 
low as a few picowatts, and in a single measurement can cover a dynamic 
range of seven orders of magnitude, allowing for the simultaneous 
viewing of low intensity and high intensity signals such as spontaneous 
emission and laser emission from a laser cavity. It has several 
integrated measurement modes, from simple optical absorption 
measurements to full optical amplifier parameter analysis. This unit 
supports diverse analysis functions for DWDM and other optical devices 
(LD, LED, FBG, etc).
