High resolution spectral analysis in 1440nm to 1640nm at fast sweep rate
Large 52dB (>40dB spurious free) dynamic range
Very high wavelength accuracy (1.5pm/190MHz relative)
Benefits
Large dynamic range helps identify weak spurious spectral features near stronger signals
High wavelength accuracy allows precise frequency measurement on closely-spaced optical signals
High input power allows characterization of non-linear effects in amplified systems
The Keysight 83453B High Resolution Spectrometer makes extremely fine sub-picometer spectral resolution measurements on tunable lasers, transmitters and systems.
