The Agilent/Keysight 86142A is a benchtop optical spectrum analyzer engineered for high-resolution spectral analysis across 600 nm to 1700 nm. It delivers exceptional wavelength accuracy—±0.025 nm (1510–1570 nm) and ±0.035 nm (1570–1640 nm) after internal calibration—and maintains ±0.003 nm tuning repeatability. The instrument achieves –90 dBm sensitivity in the 1250–1610 nm band and handles maximum input power of +30 dBm total across the full spectrum. Eight selectable resolution bandwidths range from 0.06 nm to 10 nm FWHM, enabling precise characterization of DWDM systems, EDFA performance, and passive optical components. Dynamic range reaches –70 dB in the 1550 nm band at ±0.5 nm span with 0.1 nm resolution. Scale fidelity holds ±0.05 dB characteristic for fixed reference level measurements. Wavelength reproducibility of ±0.002 nm and polarization dependence as low as ±0.05 dB support demanding R&D and production test environments demanding accuracy and stability.
