Full Line-up of Functions and Applications

In addition to its excellent basic performance, the MS9720A
has a full line-up of useful functions. The basic waveform
analysis functions offer applications for evaluating every
important item in WDM systems.

The following screens show threshold and SNR analysis of
a WDM signal waveform. The effective analysis range is set
using the Zone Marker even for WDM signals, enabling inde-
pendent analysis of the waveform of each channel.

Insertion Loss Measurement

At insertion loss measurement, the insertion loss of optical
devices such as optical couplers can be measured. The fol-
lowing screen shows a measurement of the transmission
characteristics of a band pass filter.

In addition, the measurement results for a specified WDM
channel wavelength can be displayed as a list.

The following diagrams show the setup when measuring the
insertion loss of a WDM coupler using the built-in SLD, or an
external light source.
