   ADVANTEST TQ8325   Description / Specification:    
ADVANTEST TQ8325 480 to 1600 nm Optical Wavelength Meter

The Advantest TQ8325 Optical Wavelength Meter enables precision measurement of laser and light emitting diode wavelengths and frequency. Its main features are as follows: measurement of wavelengths from 0.48 to 1.6 micrometers and frequency from 187 THz to 625 THz without replacing input connector; measurements have accuracy of ± 5 ppm and high resolution of 0.001 nm / 100 MHz; unit displays the difference between the result of the first measurement of deviation and that of the second measurement and can measure the optical frequency and shifted waveform; measurement time is at measurements/s (the fiber connector input method is used to enable easy input of the light to be measured; GPIB and D/A conversion analog output is standard; and the conditions of panel are backed up from the battery.

*This is a Web introductory price for one calibration of the ADVANTEST TQ8325. 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.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Extinction Ratio (ER)
Extinction Ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, (example a laser diode), where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage.

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.

Wavelength Repeatability
Wavelength Repeatability is the random uncertainty in reproducing a wavelength after detuning and re-setting the wavelength. The wavelength repeatability is ± half the span between the maximum and the minimum value of all actual values of these wavelengths. Example test condition: uninterrupted TLS output power, constant power level, temperature within operating temperature range, coherence control off, short time span. Note: NOTE The long-term wavelength repeatability can be obtained by taken the wavelength repeatability and wavelength stability into account.
