Power Measurement
How to Measure Power
principally for polarization dependent measurements, but can be
used for other types of measurement.
You can choose three modes of operation from the MinMax mode
menu:
•
<C
> mode, which compares each new measured
ONTINUOUS
value with the maximum and minimum values so far, and
replaces them as necessary.
This mode is useful for measuring the Polarization Dependent
Loss (PDL) of a component. Run the application while
sweeping the polarization of the source applied to the
component.
•
<W
> mode, which compares each new measured value
INDOW
with the maximum and minimum values of each of the
previous N samples. When a new measurement is taken it is
added to a buffer containing the previous N samples and the
oldest measurement is deleted.
•
<R
> mode, which adds each new measurement to a
EFRESH
buffer. The minimum and maximum values, in this buffer, are
displayed. After N samples are added to the buffer, the buffer
resets and a new buffer is created.
You can use Window and Refresh modes, for example, when
you are searching for or setting the position of minimum PDL.
