HP 71450B, 71451B, and 71452BOptical Spectrum AnalyzersTechnical SpecificationsSpectral Measurementsfrom 600 to 1700 nm ArrayThe HP 71450B, 71451B, and 71452B are diffraction-grating-based optical spectrum analyzers that provide spectral measurements of optical power versus wavelength and advanced functions for measuring and characterizing optical components, amplifiers, LEDs, DFB lasers, and Fabry-Perot lasers.This technical specifications sheet describes the measurement accuracy and operating conditions of the HP family of optical spectrum analyzer systems. The HP 71450B includes an HP 70950B module, the HP 71451B includes an HP 70951B module and the HP 71452B includes an HP 70952B module.The specifications apply to all functions autocoupled over the temperature range 0 to 55°C and relative humidity <95% (unless otherwise noted). All specifications apply after the instrument’s temperature has been stabilized after 1 hour continuous operation and the auto-align routine has been run. Unless otherwise noted, specifications apply without USER CAL.Characteristics and SpecificationsThe distinction between specifications, characteristics (shown in italicized text), typical performance, and nominal values is described as follows:• Specifications describe warranted performance.• Characteristics provide useful, but nonwarranted information about the functions and performance of the instrument.• Typical Performance, where listed, is not warranted, but indicates performance which most units will exhibit.• Nominal Value is an expected, but not warranted, value of the parameter.Monochromator Insertion Loss: (into 62.5 µm fiber)(See characteristic plot)*850 nm <19 dB 1300 nm < 7 dB 1550 nm<10 dBMaximum input port+20 dBm per 5 nm;

Multiple angles are a result of the multimoding in the larger fiber.•Differential Accuracy indicates the maximum error in measuring the wavelength difference between two signals that are within the specified separation.•Reproducibility refers to the amount of wavelength drift which can occur over the specified time while the OSA is tuned to a specific wavelength.•Tuning Repeatability refers to the wavelength accuracy of returning to a wavelength after having tuned to a different wavelength.Resolution•FWHM refers to the Full-Width-Half-Maximum resolutions that are available. This indicates the width at half power level of the signal after passing through the resolution slits.Amplitude•Scale Fidelity refers to the potential errors in amplitude readout at amplitudes other than at the calibration point. This specification is sometimes called linearity.•Flatness defines a floating band which describes the error in signal amplitude over the indicated wavelength range. (This error may be removed at a given wavelength by performing the user ampli-tude calibration.)•Polarization Dependence refers to the amplitude change that can be seen by varying the polarization of the light entering the OSA. This is not to be confused with amplitude variations caused by the varying distribution of energy between the different modes in fiber that are multimode at the wave-length of interest.Sensitivity•Sensitivity is defined as the signal level that is equal to six times the RMS value of the noise. Displayed sensitivity values are nominal. Slightly lower values may have to be entered to achieve specified sensitivity. Dynamic Range•Dynamic Range is a measure of the ability to see low-level signals that are located very close (in wavelength) to a stronger signal. In electrical spectrum analyzers, this characteristic is generally called shape factor.Sweep Time•Maximum Sweep Rate refers to the maximum rate that the instrument is able to acquire data and display it. This rate may be limited by multiple internal processes.•Sweep Cycle Time refers to the time required to make a complete sweep and prepare for the next sweep. It can be measured as the time from the start of one sweep to the start of the next sweep. Photodetector Input•Scale Fidelity: For any measurement with fixed Reference Level refers to the maximum error in a single power measurement. It also refers to the maximum error in the difference between two power measurements where the reference level was not changed between the measurements.•Scale Fidelity: For Multiple Measurements with Different Reference Levels refers to the maximum error between two measurements when the reference level must be changed between the measurements. 1With applied input fiber 9/125 µm2Characteristic3Temperature range 20°C to 30°C4Signal value >6 times the RMS noise value5To within 20 dB of the sensitivity noise limit6For resolutions ≥0.2 nm7Calculated from specified values; 1.15 x RSS of polarization sensitivity, scale fidelity, RBW accuracy, (and step response accuracy in pulse mode). 8With applied input fiber that is standard single mode at wavelength of interest9Sweep cycle time includes forward sweep time plus overhead between sweeps.HP 71450B HP 71451B HP 71452B Available OptionsHP 70950B HP 70951B HP 70952B Option 001 Built-in programmable current source yes yes yes Option 002 Built-in white light source yes yes yes Option 003 Swept PDL kit not availableyes not availableOption 010 Delete FC/PC interfaceyes yesyes Option 051 EDFA interpolation test personality yes yes included Option 052 EDFA time domain test personality yes yes included Option 053 EDFA noise gain profile measurement personalityyes yes included Option 122Improved dynamic range and noise marker accuracyNoNoYesOrdering InformationData Subject to Change Copyright © 1995, 1996Hewlett-Packard Company Printed in U.S.A. 9/975963-7040EAdditional Interface Connectors:HP 81000AI Diamond HMS-10HP 81000GI D4HP 81000KI SCHP 81000SI DIN 47256HP 81000VI STHP 81000WI BiconicHP 81000FB FC/PC Bare fiber adapterFor more information aboutHewlett-Packard test and measure-ment products, applications,services, and for a current sales office listing, visit our web site,/go/tmdir.
