Spectrum Analyzers

THE SPECTRUM ANALYZERS from Bristol Instruments provide the most complete wavelength and spectral characterization of CW and high-repetition rate pulsed lasers that operate from 375 nm to 12 µm. These systems combine proven Michelson interferometer-based technology with fast Fourier transform analysis for accurate measurement of absolute wavelength to ±0.0001 nm and high resolution spectral analysis to 2 GHz. As with all products from Bristol Instruments, every measurement is guaranteed by continuous calibration with a built-in wavelength standard. This ensures the most meaningful experimental results for scientific applications and for the most reliable testing of DWDM signals.

	721 Series:  CW and pulsed lasers, 375 nm – 12 µm The 721 Series Laser Spectrum Analyzer operates both as a high-accuracy wavelength meter and a high-resolution spectrum analyzer resulting in the most complete spectral characterization of CW and pulsed lasers. Absolute laser wavelength is measured to an accuracy as high as ±0.2 parts per million, and the laser’s spectrum is determined to a resolution as high as 2 GHz. Continuous calibration with a built-in wavelength standard provides the reliable accuracy that is expected from Bristol Instruments.

	428 Series:  Multi-wavelength, CW and modulated signals The 428 Series Multi-Wavelength Meter simultaneously measures wavelength, power, and OSNR in order to fully characterize DWDM components and DWDM transmission systems. The model 428 combines high accuracy and exceptional reliability to achieve the most meaningful test results. Straightforward operation and rugged design satisfy the needs of both the R&D scientist and the manufacturing engineer.
