Beschreibung: Optical Spectrum Analyzer
Informationen:
                                    The Q8347 is an optical spectrum analyzer employing a
Michelson interferometer. Its main features
are given below.
Features
•
High-resolution wavelength measurement
The analyzer measures wavelength with high resolution of
0.01 nm at 1.5/^m band and
0.001 nm at 0.5/дп band.
Therefore, the analyzer can analyze the devices used for
multi-mode light or wavelength
division multiplexing that cannot be dissolve heretofore.
•
Coherent length can be measured.
The coherent length which cannot be measured by dispersion
spectroscopy using a grating
can be measured by the Q8347 using the interference method.
Therefore, the Q8347 can
easily determine the noise suppression performance of the
CD/VD laser diode due to the
•
reflected light. The analysis range is as wide as ± 165mm.
High-speed measurement
As the analyzer employs Fourier spectroscopy using an
interferometer, high-speed
measurement is realized.
Even when the GP!B is used in system, the entire procedure
from the measurement start
trigger to data output can be carried out in 2.5 seconds (in
the high-resolution mode) or in
1.0 second (in the normakesoiution mode). (In this case, the
wavelength range is the long
wavelength.)
•
±0.01nm wavelength measurement accuracy
As a He-Ne laser is used as the internal reference light
source, a high wavelength accuracy
of 0.01 nm is realized. Wavelength calibration is not required.
•
Easy operation
Various aspects have been taken into consideration to make
measurement easier.
The panel key arrangement, Softkey menus and basic key
functions can be specified in the
first hierarchy.
The Q8347 has a built-in level meter which greatly
facilitates adjustment of the
•
measurement light coupling.
Zoom function
The measurement data can be analyzed again and displayed
with the zoom function.
Data can be displayed from wide to narrow span without
repeating measurement.
•
Various processing functions
Various processing functions are available. They include
four types of FWHM (full width
half maximum) measurement function, an automatic peak search
function, four types of
cursor indication modes, a peak value listing function and
16 data memory areas.
•
Built-in high-speed printer
Measurement data can be easily output using a high-speed
thermal printer having a printing
speed of less than 8 seconds.
