HP Agilent 86142A Optical Spectrum Analyzer (OSA)

The Agilent 86142A is a high-accuracy benchtop optical spectrum analyzer (OSA) designed for WDM system and component testing. It’s part of Agilent’s 8614xA family and is prized for its excellent dynamic range, fast sweep speeds, and built-in measurement applications tailored for both R&D and manufacturing environments. Here’s a quick rundown of its capabilities: Wavelength range: 600 to 1700 nm Resolution bandwidths: Selectable from 0.06 to 10 nm Wavelength accuracy: ±0.025 nm (1510–1570 nm), ±0.035 nm (1570–1640 nm) Dynamic range: Excellent close-in performance for dense WDM analysis Sweep speed: Fast, even at high sensitivity Applications: Built-in tools for WDM channel analysis, passive component testing, and more Interface: PC-style optical interface (Agilent 81000xI series) It’s a workhorse for labs needing precise spectral measurements across the C and L bands, and it’s still widely used despite being discontinued.
