6-point OSNR measurement

Multi Channel Analysis

WaveAnalyzer GUI

Measurement Analysis Functions

The PC based GUI package offers various analysis functions:

The 3-point-measurement allows very simple and quick OSNR

measurements using the traditional approach in which a 0.1nm resolu-

tion bandwidth measurement scan is taken from which the noise and

the signal powers are estimated.

The advanced 6-point-measurement allows OSNR measurements

even between densely spaced channels, see figure on the right. The

measurement bands can be precisely adjusted to capture the noise

floor and the signal accurately.

The polarization extinction ratio method allows in-band OSNR

measurements, provided the optical signal is single polarization only

(which can be verified with the WaveAnalyzer instrument).

The sequential measurement method supports in-band OSNR

measurements of dual-polarization signals.

The Multi Channel Analysis function provides measurements of the

OSNR, channel power and channel center frequency of all channels

simultaneously with an update rate of up to 10 Hz, depending on

scan range. For documentation or further analysis, the results can be

exported in a table.

The Wavelength Meter function provides fast measurements of the

power and the wavelength of multiple narrow band signals. It can

measure several hundred lines simultaneously and provides a wave-

length accuracy which is similar to dedicated wavelength meters.

The WaveAnalyzer GUI contains a powerful marker scheme which

supports further analysis capabilities, like peak detection, display

of difference frequencies and integrated power in user definable

frequency ranges.

The WaveAnalyzer 1500S/1500B includes a trigger scheme which

supports taking gated measurements. This enables, for example, taking

spectral measurements of signals traveling in recirculating loops.

HTTP based programming interface

The WaveAnalyzer family offers a RESTful HTTP based Application

Programming Interface (API).

Web server

The WaveAnalyzer instrument includes a Web Server GUI which

allows controlling the instrument and taking measurements with a

web browser.
