Principle of a Full Spectrum Light Analyzer
Spectrum analyzer types are distinguished by the methods used to obtain the spectrum of a signal. There are swept-tuned and fast Fourier transform (FFT) based spectrum analyzers: • A swept-tuned analyzer uses a to a portion of the input signal spectrum to the center frequency of a narrow, whose instantaneous output power is recorded or displayed as a function of time. Some typical applications are: testing of optical systems, for example wavelength division multiplexing systems in optical fiber. Chapter 2 defines many of the specified performance parameters of diffraction-g rating-based optical spectrum analyzers and discusses the relative merits of the single monochromator, double monochromator, and double-pass-monochromator- ased optical spectrum. This information pertains to any Applied Analytics product which uses the nova II UV-Vis/SW-NIR Spectrophotometer.
