Agilent Technologies, Inc. 71451B Optical Spectrum Analyzer
Feature:
Wavelength: 600nm
Wavelength resolution: 0.08nm
Dynamic Range: -70dB
With its unique operating modes, the HP 71451B is the one OSA that can fully characterize your optical devices. In addition to optical sources, the HP 71451B can characterize optical-to-optical devices such as couplers, filters, isolators, switches, and wavelength division multiplexers. Through the use of the transimpedance input, the HP 71451B can also measure the responsivity of your photo diodes as a function of wavelength.
The HP 71451B measures insertion loss, filter bandwidths, cross talk, and (with Option 003) polarization dependent loss of optical-to-optical components, as a function of wavelength. By accessing the transimpedance input, found only on the HP 71451B, the electrical output of your photo diodes can be measured, as a function of wavelength, to determine their responsivity. Use the optional programmable current source to bias your photo diodes and characterize the responsivity as a function of bias current.
