WAVEANALYZER™

WaveAnalyzer 1500S

High Resolution Optical Spectrum Analyzer

The WaveAnalyzer 1500S Optical Spectrum Analyzer is a real-time,

very-high-resolution optical spectrum analyzer for R&D and production

test applications. Based on Coherent’s fast-stepping solid-state laser, the

WA 1500S uses coherent detection techniques to achieve an outstanding

combination of resolution, dynamic range and measurement speed. Instru-

ment versions are available for C- and L-bands.

This next-generation Optical Spectrum Analyzer provides spectral

measurements with sub-pm resolution at an update rate of 4 measure-

ments per second across the entire C- or L-band. Scanning across smaller

spectral regions is even faster, with update rates of over 10 measurements

per second across any 200 GHz window, enabling interactive adjustment of

optical components and systems.

The WaveAnalyzer’s coherent receiver provides polarization resolved data

of the signal while its two input ports, for different power levels, ensures

coverage of a large range of optical input signals. Low power single

channel signals can be analyzed as accurately as high power WDM signals.

The WA 1500S is very compact and rugged, as it contains no moving parts.

It is controlled using a USB or Ethernet connection to a Windows-based

computer which runs Coherent’s WaveAnalyzer software package.
