This performance test uses the Infinium 86100A Optical Oscilloscope
(DCA) with appropriate Optical Plug-in modules and built-in filters. If a
different oscilloscope is used refer to the oscilloscope information for
Optical Eye Mask measurement.

The OTU-1 and OTU-2 pulse mask files may not be available on your
Oscilloscope. If required these can be obtained from the Agilent.com web
site at http://www.agilent.com/comms/omniberotn under the heading
“Software and Drivers”

To test the OC-1/STM-0 power level and eye mask
