The HP 71451A is a diffraction-grating based optical spectrum analyzer (OSA). It provides unprecedented performance with their outstanding dynamic range, sensitivity, high amplitude and wavelength accuracy, and polarization insensitivity. The HP 71451A extends the capabilities of the HP 71450A by adding an optical transfer switch. This switch provides access to key points in the spectrum analyzer block diagram. The monochromator output allows the input optical signal to be filtered by the monochromator with all resolution bandwidths available. This instrument performs measurements quickly, especially when high sensitivity is required. Capable of sweeping 40 nm in 50 ms with reduced dead time, the analyzers can save hours of measurement time. In addition, the HP 71451A can be left continually sweeping; you no longer need to stop the sweep to save wear and avoid costly repairs. The HP 71451A includes automatic features. An automeasure function quickly locates the signal, zooms in, and centers the display. An auto-align feature automatically centers the light on the photodiode for optimum amplitude accuracy and removes the need for fiber alignment on the monochromator output. The analyzers include built-in programs for advanced measurement on DFB and Fabry-Perot lasers and LEDs. Wavelength range: 600 nm to 1700. Wavelength Tuning repeatability: ±0.005 nm.
