HP 71400C Lightwave Signal Analyzer

The HP 71400C lightwave signal analyzer combines HP's high-performance microwave and RF spectrum analyzers with a sensitive wide-bandwidth optical receiver module, producing calibrated instrumentation for characterizing semi-conductor lasers, laser transmitters, optical modulators, and detectors.

Featuring bandwidths from 100 kHz to 22 GHz and wavelength operation from 1200 to 1600 nm or, with Option 850, from 750 to 870 nm, the HP 71400C easily and accurately charaterizes lasers and devices for modulation capability. It can make measurements of relative intensity noise (RIN), linewidth, and modulation performance with analog or digital format on a single-mode optical fiber.

The HP 71400C is part of the modular measurement system (MMS). This system provides an easy way to add additional capability to your lightwave signal analyzer such as; optical spectrum analyzer modules and tracking generator modules.
