ADVANTEST Q8221 2-Ch Optical Multi Power Meter

The Advantest Q8821 Optical Multi Power Meter employs a two-channel plug-in system. Various optical sensors and light sources are available as plug-in units. The two channels of the Q8221 can be used individually or simultaneously. Free combination of optical sensors and light sources enables diverse applications. The optical sensors for Q8221 assure high accuracy of ±2.5% at calibration point. In broad band wavelength region, they assure ±4.5% accuracy by compensating the sensitivity curve over wavelengths of each sensors. Further more, the linearity of ±0.5% is assured. Not only at the calibration point, these sensors also assure at the broad band wavelength region and the level to be measured. For all sensors, the Q8221 achieves a sampling speed of 100 times/sec. and a ranging speed (time required to move to a different range) of a maximum of 500 msec (minimum 20 msec). In addition, GPIB output can be transferred at a high speed of 100 times/sec., thus dramatically increasing the throughput of production lines. The Q8221 is capable of storing data containing 400 points with the A and B channels independently. Furthermore, stored data can be directly output to an external plotter as a graph. Also, PDL measurement is very easy with Q8221, because Q8221 can display maximum and minimum values as well as the difference between the maximum and minimum values of the measured data. Specifications. Sensor plug-in channels: 2 (Channels A and B). Resolution: dBm/dB display: 0.001 dB (or 0.0001 dB for data output via GPIB) W display: Max.199,999 counts. Measurement mode: CW or chopped light (270 Hz) measurement mode selectable. Averaging function: The number of averaging can be set to 2 to 256 using the running averaging method. GPIB interface: IEEE488-1978.

*This is a Web introductory price for one calibration of the ADVANTEST Q8221. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

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.
