High-Speed Power Meter 55
7 Performing Typical Tests with
Your PM-1600
To make accurate, meaningful, and repeatable power measurements, it is
important to consider the following points:
Connectors, fiber ends, ports, and detectors should be clean at all
times.
A null measurement should be performed prior to each user session or
whenever there is a significant change in ambient temperature. To
perform a null measurement, see Nulling Electrical Offsets on page 11.
The optical source should be stable.
Appropriate test jumpers, connectors, and adapters must be used.
Once a reference has been taken, ensure that the setup remains
stable. To take a reference, see Measuring Relative Power on page 16.
Since optical losses vary according to the launch, receive conditions,
and fiber type, controlling these conditions with mode filters and
strippers is essential.
