The Keysight Z2002-86142 is a Network Expansion System component for the 86142B Optical Spectrum Analyzer, a benchtop instrument engineered for high-precision spectral analysis in WDM component and system testing. This OSA delivers exceptional wavelength and power accuracy, dynamic range, and low polarization dependency for demanding optical network applications.
– Technical Specifications
The analyzer operates across the 600 nm to 1700 nm wavelength range, covering S, C, and L bands. Wavelength accuracy reaches 10 pm with user calibration, while reproducibility maintains ± 0.002 nm with a 9/125 µm input fiber over ≤ 1 minute intervals. The span range extends from 0.2 nm to full range with zero span capability.
Sensitivity is defined as signal values exceeding 6 × RMS noise. Absolute accuracy applies for resolution ≥ 0.1 nm with 9/125 µm fiber. Polarization dependence specifications apply at resolution ≥ 0.2 nm, room temperature, and 9/125 µm fiber. Operating conditions specify 0 °C to 55 °C ambient temperature and relative humidity < 95%, after one hour stabilization and auto-align execution.
Flatness defines the floating-band amplitude error across the specified wavelength range and can be corrected through user amplitude calibration. Scale fidelity addresses amplitude readout linearity at points other than the calibration reference.
