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 .

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence is the pattern and or relationships of waves due to phase properties.

Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
