The Agilent/Keysight 86145B is a portable optical spectrum analyzer engineered for high-precision spectral analysis across demanding WDM and optical component testing. Operating across the 600 nm to 1700 nm range, this instrument delivers wavelength accuracy of ± 0.01 nm in the 1480–1570 nm band with 60.0 pm resolution and -70 dB dynamic range. Built-in test applications accelerate measurement workflows for amplifiers, sources, WDM systems, and passive components using a fast dual-sweep method that completes 500 nm spans in less than 650 ms. The 86145B covers S, C, and L bands with wavelength repeatability of ± 0.002 nm and polarization dependency of ± 0.25 dB across 1250–1650 nm, making it suitable for laboratory and field deployment.
