Optical Spectrum Analyzer
Technical Specifications
November 2005
• Full-Feature Optical Spectrum Analyzer
Exhibits excellent speed and dynamic range with
convenient and powerful user interface.
• Filter Mode
Wavelength - filtered signal can be coupled to a
single-mode fiber output for tunable-filter and
channel-drop applications.
• Dispersion penalty calculation
Dispersion Penalty calculation software combines
86146B and 86100C to measure time-resolved
chirp and calculate dispersion penalty.
Characteristics and Specifications
The distinction between specifications and characteristics is described as follows:
• Specifications describe warranted performance.
• Characteristics provide useful, but non-warranted information about the functions and performance of the instrument.
The specifications apply to all functions, with video bandwidth 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 1hour continuous operation and the
auto-align routine has been run. Unless otherwise noted, specifications apply without USER CAL.

86146B-006 Wavelength Calibrator
Figure 1: Wavelength calibrator block
Figure 2: Wavelength calibrator absorption spectrum
The wavelength calibrator option provides an onboard wavelength reference that can be used to automatically
calibrate the optical spectrum analyzer. The calibrator is based on an EELED and an Acetylene gas absorption
cell, Figure 1. The Acetylene absorbs light at very specific wavelengths based on the molecular properties of gas.
The cell is illuminated by an EELED and the OSA uses the absorption pits to perform a wavelength calibration,
Figure 2. Since the absorption of the Acetylene gas is a physical constant it never needs calibrating.
The wavelength calibrator enhances the OSA to achieve better than ±10 pm wavelength accuracy and removes
the need to use a tunable laser source and multi-wavelength meter as an external reference.

Definition of Terms
Absolute Accuracy (after user cal) refers to the wavelength accuracy after the user has performed the
internal wavelength calibration using a source of known wavelength.
Reproducibility refers to the amount of wavelength drift, which can occur over the specified time while
the OSA is swept across a source of known wavelength.
Tuning Repeatability refers to the wavelength accuracy of returning to a wavelength after having tuned
to a different wavelength.
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.
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 amplitude
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 wavelength of
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
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 when using default number of trace
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.
