ADVANTEST Q8381A 350 to 1750 nm  Optical Spectrum Analyzer

The Advantest Q8381A optical spectrum analyzer can analyze a wide wavelength band from 350 to 1750 nm and a wide dynamic range from -85 to + 10 dBm (1.1 to 1.6 um), accommodating measurements on display LEDs and optical devices for communication. In addition, Advantest's unique technology realizes low polarization dependence and a high level measurement accuracy of ± 1.5 dB. In addition to the automatic optimum measurement condition setting, automatic peak search and half- value width measurement functions , the Q8381A mounts the pulse light measuring function, power monitoring function and luminosity compensation display functions for improvement of operation and analysis capabilities. In conventional pulse light measurement, even if a number of averagings is made and the average power of duty ratio is obtained; low level and data missing may result. The Q8381A can measure a wide wavelength range from 1.1 to 1.6 um at a high sensitivity of -85 dBm. Therefore, level measurement for spontaneous emission light from an erbium doped fib er amplifier (EDFA) and wavelength characteristic measurement in combination with white light source can be performed over a wide dynamic range. Specifications. Measurement range: 0.35 to 1.75 um. Resolution: 0.1 , 0.2, 0.5, 1.0, 2.0, 5.0 nm. Accuracy: ± 0.5 nm (23 ± 5 C), 1.0 nm (10 to 40 C). Repeatability: 0.1 nm or less (during one-minute repetitive sweep). Measurement range (input sensistivity): -75 to +10 dBm (0.7 to 1.6 um). Level Accuracy: ± 1.5 dB or less (at wavelength of 0.633, 1.31, and 1.55 um). Linearity: ±0.5 dB/ 20 dB or less, ±1.0 dB/ 40 dB or less. Scale: 0.2, 0.5, 1.0, 2.0, 5.0, 10.0 dB/DIVand linear. Measurement time: 0.8 sec or less (with a span of 200 nm or less), 1.5 sec or less (with a span of 500 nm or less).

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.
