收購/回收 AQ6315A 光譜分析儀 AQ6315A 

 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）.

This unit has the following specifications:
Wavelength Range: 350 - 1750 nm
Resolution: 0.05 nm
Sensitivity: -65 dBm
Maximum Power: +20 dBm
High wavelength accuracy: ? 0.05 nm wavelength accuracy in the 1550 nm band, with ? 0.02 nm wavelength linearity
Dynamic Range: 70 dB
High-level accuracy: ?0.3 dB
High power measurement: +20dBm （100 mW）
Built-in GPIB Interface
Three individual trace memories
9.4-inch color LCD
