Using the softkeys Arrows allow you to navigate from field to field in the dialog box. The high- lighted parameter can be changed.
Page 45 Using the Instrument Setting Up Measurements Operating the Internal White Light Source For Option 002 only Option 002 provides a built-in white light source which is a stable, broadband light source for swept-wavelength stimulus response testing from 900 nm to 1700 nm.
Page 46 Using the Instrument Setting Up Measurements æ ö -- - log A log B – è ø 1 Connect the Light Source Output to the Monochromator Input using the short 62.5/125 µ m fiber. The standard connector interface is FC/PC.
Page 47 Using the Instrument Setting Up Measurements Averaging Traces Trace averaging improves your measurement repeatability by smoothing out noise. For measurements involving slow polarization scrambling, using video filtering to improve repeatability will require a very narrow video bandwidth (less than 10 Hz). This would result in a long measurement time, where trace averaging would be faster.
Page 48 Using the Instrument Setting Up Measurements Setting Video Bandwidth Video bandwidth filtering occurs after the detection of the light. In the auto coupled mode, the video bandwidth has an extremely wide range. This allows the instrument to avoid unnecessary filtering that would reduce the sweep speed more than required.
Page 49 Using the Instrument Setting Up Measurements video bandwidth and sensitivity, it is recommended that either the sensitivity or the video bandwidth be changed, whichever is the most important to the measurement task being performed. To reduce noise, you can select a narrower video bandwidth to improve repeatability and sensitivity or select a wider video bandwidth to shorten over- all measurement time.
Page 50 Using the Instrument Setting Up Measurements Setting the Sensitivity Setting sensitivity requests the lowest amplitude signal that can be measured relative to the highest amplitude signal displayed. It is defined as the signal that is six times the RMS noise. The minimum setting is –100 dB. An error will be reported for values outside of this range and the sensitivity will round to the nearest valid sensitivity.
Page 51 Using the Instrument Setting Up Measurements Triggering a Measurement Triggering a measurement synchronizes the start of the sweep to an internally generated trigger signal. Internal triggering ensures continuously triggered sweeps with the shortest delay between sweeps. Refer to “Trigger Mode, Internal”...
Page 52 Using the Instrument Setting Up Measurements The display will have at least one data sample marked as valid (high level) per trace point. Or else you can use the Max Hold function to complete a trace over several sweeps. Multiple sweeps fill the gaps because the high and low levels of the gating signal occur independent of the grating position.
Page 53 Using the Instrument Setting Up Measurements Moving the Active Function Area The active function area on the display can be moved to eight different loca- tions. This allows you to place the active area in a location that will not inter- fere with the trace information.
Page 54 Using the Instrument Setting Up Measurements Indicating an Update is Needed This feature alerts you to take a sweep after changing any sweep related parameters when the analyzer is not in sweep mode. For example, if you change the resolution bandwidth, the new resolution bandwidth is displayed on the bottom of the screen, but the trace data displayed on the screen used the previous resolution bandwidth value.
Page 55: Calibrating Wavelength Measurements
Using the Instrument Calibrating Wavelength Measurements Calibrating Wavelength Measurements Environmental variations such as air pressure, temperature, and humidity can affect the index of refraction of air in the monochromator of the optical spec- trum analyzer (OSA). This section discusses calibration methods that you can use to improve the wavelength accuracy in the Agilent 8614X OSA’s.
Page 56 Using the Instrument Calibrating Wavelength Measurements Internal Wavelength Calibration The optional internal calibrator (1513 to 1540 nm) provides a convenient method for increasing wavelength accuracy when used with an internal Enhanced Wavelength Calibration (EWC) process. The wavelength accuracy of the OSA will be ±0.2 nm over the full wavelength range of the instrument, with ±10 pm over 1480 to 1570 nm and ±25 pm accuracy over 1570 to 1620 The EWC range can be selected for either the “full”...
Page 57 Using the Instrument Calibrating Wavelength Measurements External Single Wavelength Calibration Using an external single-point calibration source allows the calibration to be done at a specific wavelength. This single wavelength user calibration can be repeated as often as necessary to correct for environmental variations and existing multipoint wavelength offsets will be adjusted accordingly.
Page 58 Using the Instrument Calibrating Wavelength Measurements External Multipoint Wavelength Calibration An external multipoint wavelength calibration can be performed over any specified wavelength range, up to and including the full wavelength range of the OSA (600 nm to 1700 nm). Narrow measurement spans can be chosen to provide greater accuracy over a selected range.
Page 59 Using the Instrument Calibrating Wavelength Measurements Wavelength Cal Setup and choosing the Offset option before running the single point calibration. To insure this offset process has provided sufficient accuracy, the wavelength readings of the multi-wavelength meter and the OSA should be compared to verify the wavelength accuracy and determine if a full multipoint wavelength recalibration is necessary.

Page 75 Using the Instrument Analyzer Operating Modes The data returned by the alignment is stored for both the external (9 µ m) and the internal (50 µ m) path. With the data stored for both paths, the alignment for the internal path is improved due to the increased resolution bandwidth of the external path.
Page 76 Using the Instrument Analyzer Operating Modes N o t e If the file saved in filter mode is recalled into an instrument with firmware revision B.04.02, a critical error occurs, indicating a grating positioning failure. Restart the instrument to clear the error and then continue making measurements.
Page 77 Using the Instrument Analyzer Operating Modes The light is output from the optical spectrum analyzer’s front panel monochro- mator output connector. This light is a filtered (by the resolution bandwidth) and attenuated (by the monochromator loss) light input to the front panel monochromator input connector.

Page 86 Function Reference Amplitude Setup Setup Panel Reference Level Position Selections The value selected for the Reference Level Position determines the position of the reference level on the graticule. Setting this value to zero divisions places the reference level on the very bottom of the grid. Setting the reference level to 10 divisions places the reference level at the top of the grid.
Page 87 Function Reference Amplitude Setup N o t e Turning Auto Zero off allows the instrument to sweep faster, but results in less accuracy on low level signals. The optical spectrum analyzer performs a more complete zeroing when the instrument is first turned on. You can run this more complete routine anytime by pressing the Zero Now softkey.
Page 88 Function Reference Amplitude Units (Amplitude Setup Panel) When AMPCOR is turned on, the correction points are applied across the active measurement range and added to all measurement results. Between points, the correction values are interpolated linearly or logarithmically. When measuring at wavelengths outside the first and last correction points, the first or last value (as appropriate) is used as the correction value.
Page 89 Function Reference Auto Align Auto Align Pressing the auto align button on the front panel of the instrument performs an automatic alignment of the instrument using the largest signal found in a full span sweep. This aligns the output of the monochromator with the photo- detector for improved amplitude accuracy.
Page 90 Function Reference Auto Align & Add to Trajectory Auto Align & Add to Trajectory Allows alignment at several wavelengths, ensuring amplitude accuracy of your measurements. Before initiating the alignment, connect a broadband light source to the front-panel input connector. (You may add and/or update the existing points in the trajectory table.) Press Auto Align Preset to clear the table.
Page 91 Function Reference Auto Meas broadband or narrowband light source. If there is insufficient signal power, the automatic measurement will not be performed, and a warning message will be reported. This automatic measurement routine is normally the best way to adjust sensitivity while maintaining the fastest sweep rates. The auto measure function uses trace A to perform the measurement.

Page 245: Cleaning Connections For Accurate Measurements
Connectors also vary in the polish, curve, and concentricity of the core within the cladding. Mating one style of cable to another requires an adapter. Agilent Technologies offers adapters for most instruments to allow testing with many different cables.
Page 246 Maintenance Cleaning Connections for Accurate Measurements • Is an instrument-grade connector with a precision core alignment required? • Is repeatability tolerance for reflection and loss important? Do your specifica- tions take repeatability uncertainty into account? • Will a connector degrade the return loss too much, or will a fusion splice be re- quired? For example, many DFB lasers cannot operate with reflections from connectors.
Page 247 0.2 µ m. This process, plus the keyed axis, allows very precise core-to-core alignments. This connector is found on most Agilent Technologies lightwave instruments. 6-10...
Page 248 Maintenance Cleaning Connections for Accurate Measurements The soft core, while allowing precise centering, is also the chief liability of the connector. The soft material is easily damaged. Care must be taken to mini- mize excessive scratching and wear. While minor wear is not a problem if the glass face is not affected, scratches or grit can cause the glass fiber to move out of alignment.
Page 249 Maintenance Cleaning Connections for Accurate Measurements Use the following guidelines to achieve the best possible performance when making measurements on a fiber-optic system: • Never use metal or sharp objects to clean a connector and never scrape the connector. • Avoid matching gel and oils. Figure 6-5.
Page 250 Maintenance Cleaning Connections for Accurate Measurements Figure 6-7. Damage from improper cleaning. While these often work well on first insertion, they are great dirt magnets. The oil or gel grabs and holds grit that is then ground into the end of the fiber. Also, some early gels were designed for use with the FC, non-contacting con- nectors, using small glass spheres.
Page 251 Maintenance Cleaning Connections for Accurate Measurements • Keep connectors covered when not in use. • Use fusion splices on the more permanent critical nodes. Choose the best con- nector possible. Replace connecting cables regularly. Frequently measure the return loss of the connector to check for degradation, and clean every connec- tor, every time.
Page 252 Cleaning Connectors The procedures in this section provide the proper steps for cleaning fiber- optic cables and Agilent Technologies universal adapters. The initial cleaning, using the alcohol as a solvent, gently removes any grit and oil. If a caked-on layer of material is still present, (this can happen if the beryllium-copper sides of the ferrule retainer get scraped and deposited on the end of the fiber during insertion of the cable), a second cleaning should be performed.

Page 254 To clean an adapter The fiber-optic input and output connectors on many Agilent Technologies instruments employ a universal adapter such as those shown in the following picture. These adapters allow you to connect the instrument to different types of fiber-optic cables.
Page 255 Maintenance Cleaning Connections for Accurate Measurements Care of Connector Savers The connector saver is used to protect the input connector of the OSA from damage. It functions as a standoff between the front panel input connector and the input fiber. If the fibers are not thoroughly cleaned, repeated connec- tions can result in a scratched, chipped, or dirty input connector.
Page 256 Maintenance Cleaning Connections for Accurate Measurements Cleaning Connector Savers The two ends of the connector saver should be cleaned differently. The ferrule fiber end of the connector saver can be cleaned in the same manner as a fiber patch cord, or a cable, using the method described below. The recessed fiber end of the input connector saver presents a different cleaning challenge.
Page 257 Maintenance Cleaning Connections for Accurate Measurements To clean the recessed end of the connector saver • To clean the recessed end of the connector saver, it is recommended that a wrapped tip swab or stick cleaner be used. Berkshire’s LT670183 wrapped tip cotton swab, or Cletop stick cleaners have proven to be an effective cleaning solution.
