ADVANTEST Q8344A 350 to 1750 nm  Optical Spectrum Analyzer

The Advantest Q8344A is an optical spectrum analyzer with a wide wavelength range from 0.35 to 1.75 um. The usage of a Fourier spectrum system using a Michelson interferometer makes it possible to analyze coherence that cannot be obtained by the dispersing spectrum systems using monochromators. It exhibits its capabilities for evaluation of laser diodes for CDs and video disks. The built-in He-Ne laser used as the reference wavelength realizes a wavelength accuracy of ± 0.1 nm (1.3 um), ensuring a long-term measurement stability even without wavelength calibration. The Q8344A provides a maximum wavelength resolution of 0.05 nm (at 0.85 um), accommodating measurements of laser diodes with narrow mode intervals. The measurement speed is approx. 1.5 seconds (at 0.4 to 1.05 um and 0.8 to 1. 75 um) regardless of the analysis span, allowing it to be used as a system component. With the versatile display, analysis and processing functions , the Q8344A can be used for characteristic measurement applications for diverse components ranging from photo emitting elements such as laser diodes and LEDs to optical components such as optical fibers and filters .

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
