WAVEANALYZER™

The WaveAnalyzer family uses a heterodyne measurement principle in which a fast sweeping laser, serving as local

oscillator (LO), is scanning across the wavelength range of interest. The beat signal, generated by mixing the local oscil-

lator signal with the signal under test, is detected by a Polarization Multiplex Receiver. The fast sweeping Modulated

Grating Y-branch laser is electronically tuned so the instrument does not contain any moving parts (except the fan in the

WaveAnalyzer 400A and 1500S/1500B).

This measurement principle provides a unique combination of measurement performance and speed. All members of the

WaveAnalyzer family can provide highest spectral resolution and maximum measurement (sweep) speed at the same time.

For example, the WaveAnalyzer (WA) 1500S/1500B provide a resolution bandwidth of 180 MHz (about 1.4 pm) while taking

measurements with update rates of up to 10 sweeps per second.

Software Package

• Graphical User Interface (GUI) included, which controls the WA 200A, the WA 400A, and the 1500S plus 1500B

• GUI serves as a viewer for measurement traces taken with the WA 200A

• WaveAnalyzer Analysis Server included, which provides comprehensive analysis capabilities on measurement data taken

with all WaveAnalyzer instruments

• Server can be accessed via a RESTful http based Application Programming Interface (API)

• Runs on Windows 10 / 11

• The WaveAnalyzer GUI Package is available for download on https://www.coherent.com/resources.
