ADVANTEST Q7606A Optical Chirpform Test Set

The Advantest Q7606A Optical Chirpform Test Set is a lightwave modulation test set, used together with a digital sampling oscilloscope, to separately measure and evaluate the chirp (frequency-modulated / FM) and intensity-modulated (IM) components of incident laser light. The Q7606A contains two sets of fiber-type Mach-Zehnder interferometers and their control circuits. The Q7606A can selectively output the sum of, or difference between the frequency-modulated / FM and IM components of the modulated incident light by switching the measurement mode. The sum (IM+FM) and difference (lM-FM) data are processed by the digital sampling oscilloscope and the personal computer to separate the chirp FM and IM components from each other, thus making it possible to evaluate the time-domain charactenstics. Specifications. Wavelength measurement range: 1530 to 1580 nm. Optical input power range: -10 to 10 dBm. Free Spectral Range: 150 GHz ±15 GHz. Demodulation band width (130 MHz as standard, 1 dB down):100 Hz to 50 GHz. Deviation of demodulation frequency: 65 GHz p-p or less. Resolution of demodulation frequency (Depends on the measurement resolution of an external sampling oscilloscope and input optical power.: 20 MHz p-p or less. Optical output power (Output optical power in average. Optical power will be automatically adjusted by the automatic gain adjustment function.): 0 dBm or higher. Built-in optical amplifier with automatic gain adjuster. Input light polarization compensation: Automatically controlled.

*This is a Web introductory price for one calibration of the ADVANTEST Q7606A. 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.

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

Linearity
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.
