Calibration Procedure Diagrams
The following diagrams supplement steps 1–4 on the previous page.
Connect known good reference jumpers between the light source and power
meter. In this example two jumpers are used in conjunction with a coupler.
This configuration allows the jumpers to be connected directly to a patch panel
when making measurements. A single jumper can also be used as long as it
is not disconnected from the light source after the calibration process.
The LCD will display the
current power level at the
power meter input. Typical
values for the 33-929
light sources are -6 to
-7dBm. Levels lower than
this (ex -15dBm) indicate
excessive loss in the
reference jumpers.
New jumpers should
be used.
