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
33-926 light sources are
-6 to -7dBm. Levels low-
er than this (ex -15dBm)
indicate excessive
loss in the reference
jumpers. New jumpers
should be used.
