Enter values in the boxes as explained below:
³
Peak detection level (dBm)
: indicates the minimum power level
from where the peak can be considered as a signal.
³
RBW for OSNR (nm)
: indicates the resolution bandwidth for the
selected OSNR value. The resolution bandwidth of an OSA
determines its ability to deal with close optical channel spacing. It
is measured as the width of the response curve at half peak power
(i.e., 3 dB down) of the instrument to a monochromatic test signal.
The instrument’s RBW value is written below the graph on the right
(below wavelength offset).
