Changing the Average Method
Before explaining how to change the setting, an explanation is given below regarding
average method.
This instrument allows use of the following three average methods.
• Hi-Speed
• Normal
• Hi-Return
Hi-Speed
This method is used to measure the entire area using the preset attenuation.
If excessive reflection occurs when the preset attenuation is not appropriate, that part of
the trace may be saturated.
This method is recommended when measuring short optical fiber cables (no
reflection in the fiber).
For saturation of trace and the method of setting the attenuation, refer to page
3-87.
The entire area is measured using the
preset attenuation.
There is a possibility that
this part of the trace is
saturated depending on
reflection level.
