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).

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
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.
