Using the Instrument Setting Up Measurements Setting Up Measurements This section contains the following information that will help you set up a wavelength measurement: • Adjusting Setup Conditions • Operating the Internal White Light Source • Averaging Traces • Setting Video Bandwidth • Using Span to Zoom In • Setting the Sensitivity • Triggering a Measurement • Moving the Active Function Area • Indicating an Update is Needed 2-2
Using the Instrument Setting Up Measurements Adjusting Setup Conditions Setup panels allow you to adjust setup conditions which are not frequently changed. Refer to “Preset” on page 3-65. Using the softkeys Arrows allow you to navigate from field to field in the dialog box. The highlighted parameter can be changed. The front-panel number keys, step keys, and knob allows the user to enter a numeric value in the highlighted field. Select selects the highlighted parameter.
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. The light source is ideal to perform stimulus-response measurements, and measure photodetector responsivity. Refer to “Light Source” on page 3-33.
Using the Instrument Setting Up Measurements A log æ ---ö = ( log A – log B ) è Bø 1 Connect the Light Source Output to the Monochromator Input using the short 62.5/125 µm fiber. The standard connector interface is FC/PC.
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. Refer to “Averaging” on page 3-14. 1 From the front panel, press Traces > Averaging.
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. Refer to “Video BW” on page 3-99. The instrument has two detection techniques: peak (auto mode) and sample (manual mode).
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 overall measurement time.
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. Refer to “Sensitivity” on page 3-81.
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” on page 3-96. In some measurements, the spectrum at a particular time within the modulation period is more important than the average spectrum.
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. Gated triggering has no time limit for the high or low level.
Using the Instrument Setting Up Measurements Moving the Active Function Area The active function area on the display can be moved to eight different locations. This allows you to place the active area in a location that will not interfere with the trace information. Refer to “Active Function Area Assist” on page 3-2. 1 Press the front-panel System key. 2 Press the Move Active Area softkey. Each press of the softkey moves the active function area to one of eight onscreen locations.
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.
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 spectrum analyzer (OSA). This section discusses calibration methods that you can use to improve the wavelength accuracy in the Agilent 8614X OSA’s. Refer to “Calibration” on page 3-17 and to “Calibrator Multi-Pt Align” on page 3-18.
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 nm.
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. After a single wavelength calibration, wavelength accuracy will be ±10 pm within 10 nm of the reference signal.
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. Calibrating the wavelength every 10 nm within the desired wavelength range is usually sufficient to improve wavelength accuracy.
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.

You can now monitor the wavelength drift of your device over time.
Using the Instrument Analyzer Operating Modes Analyzer Operating Modes This section discusses the following analyzer modes that you can use in specific measurement applications.
Using the Instrument Analyzer Operating Modes When the analyzer enters the filter mode, the sweep stops with the analyzer filter tuned to the center wavelength. (If a marker is on, the analyzer filter is tuned to the marker wavelength.) The last trace remains displayed to show the input spectrum before the filtering. A marker shows the wavelength of the preselection.
Using the Instrument Analyzer Operating Modes Table 2-6.
Using the Instrument Analyzer Operating Modes Accessing the filter mode (for 86144B/86146B only) Note Filter mode will not function in zero span. The filter mode selection will be shaded out. The current state before entering filter mode will not be saved. A sweep will not be taken. The reference level will not change. 1 Connect the light source to the optical spectrum analyzer’s front panel monochromator input connector. 2 Connect the monochromator output to the photodetector input.
Using the Instrument Analyzer Operating Modes The data returned by the alignment is stored for both the external (9 µm) and the internal (50 µm) 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. Once the align is complete or if you select No Auto Align, the instrument will be ready to detect data through the external path.
Using the Instrument Analyzer Operating Modes Note 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. Filter Mode For Agilent 86141B only In the filter or instrument mode, the analyzer acts as a fixed-tuned, variable wavelength, variable bandwidth, bandpass filter.
Using the Instrument Analyzer Operating Modes The light is output from the optical spectrum analyzer’s front panel monochromator 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. 5 Press Marker Tune (Applications > Measurement Modes > Filter Mode > Marker Tune). Turn the front panel knob to tune the preselector to any displayed wavelength.
Using the Instrument Analyzer Operating Modes Time Resolved Chirp For Agilent 86146B option TRC only The Agilent 86146B, with the filter mode capability, will measure side mode suppression ratio (SMSR), wavelength, and power. With the addition of an Agilent 86100 Infinium Digital Communications Analyzer (DCA), dedicated software (86146B Option TRL), and a personal computer, time resolved chirp (TRC) of a modulated laser can be calculated.

Function Reference Amplitude Setup Amplitude Setup Accesses the Amplitude Setup panel that allows you to specify amplitude related functions: • • • • • • • • • amplitude correction mode amplitude correction sel amplitude units auto chop mode auto ranging auto zero power calibration reference level position user power cal date The Amplitude Setup panel 3-6
Function Reference Amplitude Setup Setup Panel Selections Reference Level Position 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. Pressing the front-panel Preset key resets the reference level to 9.0 divisions.
Function Reference Amplitude Setup Note 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. Auto Chop Mode (Not available on 86144B/86146B models) Enables the optical spectrum analyzer chop mode.
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.
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 photodetector for improved amplitude accuracy. To ensure maximum amplitude accuracy and stability, connect an input signal to the instrument, mark the peak of the signal, and then press Auto Align.
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. Turn on an active marker and manually place the marker at the desired wavelength.
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.
Function Reference Auto Ranging (Amplitude Setup Panel) Note None of the Automeasure Setup parameters are affected by the front-panel Preset key. They are not saved as part of the measurement setup.
Function Reference Auto Zero (Amplitude Setup Panel) Auto Zero (Amplitude Setup Panel) Turns Auto Zero on and off. Auto Zero on enables the internal amplifiers to be zeroed between sweeps. In this mode, the instrument compensates for temperature-related current drift between each sweep. Although this “zeroing” increases amplitude accuracy, it also increases the time between sweeps. If amplitude accuracy is not critical to your measurement, turning off auto zero will improve throughput.

This setting controls only the normal marker X-axis and the delta reference immediately displayed information. This setting controls all four normal markers. The bandwidth and delta offset markers have their own settings.
Function Reference Marker Setup Peak Excursion Determines (in dB) which side modes are included in the measurements. To be accepted, each trace peak must rise, and then fall, by at least the peak excursion value about a given spectral component. The default value is 3 dB. Setting the value too high may result in not identifying a side mode. Setting the value too low may cause unwanted responses, including noise spikes, to be identified. Use the Marker Setup panel to change the peak excursion value.
Function Reference Marker Setup Changing the pit excursion. The pit searches may not recognize valid signals near the noise floor when the pit excursion definition is less than 3 dB. Thus, before performing pit searches on signals near the noise floor, reduce the pit excursion value. However, reducing the excursion value often causes pit searches to identify noise spikes.

CAUTION Use of other cleaning materials or fluids may damage the printer. 8 After the printer head has thoroughly dried, use the printer head lever to return the printer head to its original position. 9 Replace and secure the sheet-metal cover for the printer head. 10 Replace the printer paper, and close the printer access door.
Maintenance Cleaning Connections for Accurate Measurements Cleaning Connections for Accurate Measurements Today, advances in measurement capabilities make connectors and connection techniques more important than ever. Damage to the connectors on calibration and verification devices, test ports, cables, and other devices can degrade measurement accuracy and damage instruments.
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 specifications take repeatability uncertainty into account? • Will a connector degrade the return loss too much, or will a fusion splice be required? For example, many DFB lasers cannot operate with reflections from connectors. Often as much as 90 dB isolation is needed. Figure 6-2.
Maintenance Cleaning Connections for Accurate Measurements Figure 6-3. Universal adapters to Diamond HMS-10. The HMS-10 encases the fiber within a soft nickel silver (Cu/Ni/Zn) center which is surrounded by a tough tungsten carbide casing, as shown in Figure 6-4. Figure 6-4. Cross-section of the Diamond HMS-10 connector. The nickel silver allows an active centering process that permits the glass fiber to be moved to the desired position.
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 minimize 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. Also, if unkeyed connectors are used, the nickel silver can be pushed onto the glass surface.
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. Clean, problem-free fiber end and ferrule. Figure 6-6. Dirty fiber end and ferrule from poor cleaning.
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 connectors, using small glass spheres. When used with contacting connectors, these glass balls can scratch and pit the fiber.
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 connector possible. Replace connecting cables regularly. Frequently measure the return loss of the connector to check for degradation, and clean every connector, every time. All connectors should be treated like the high-quality lens of a good camera.
Maintenance Cleaning Connections for Accurate Measurements Visual inspection of fiber ends Visual inspection of fiber ends can be helpful. Contamination or imperfections on the cable end face can be detected as well as cracks or chips in the fiber itself. Use a microscope (100X to 200X magnification) to inspect the entire end face for contamination, raised metal, or dents in the metal as well as any other imperfections. Inspect the fiber for cracks and chips.
Maintenance Cleaning Connections for Accurate Measurements Table 6-4. Dust Caps Provided with Lightwave Instruments Item Agilent Part Number Laser shutter cap 08145-64521 FC/PC dust cap 08154-44102 Biconic dust cap 08154-44105 ST dust cover 1401-0291 To clean a non-lensed connector CAUTION Do not use any type of foam swab to clean optical fiber ends. Foam swabs can leave filmy deposits on fiber ends that can degrade performance.
Maintenance Cleaning Connections for Accurate Measurements If the performance, after the initial cleaning, seems poor try cleaning the connector again. Often a second cleaning will restore proper performance. The second cleaning should be more arduous with a scrubbing action. 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.
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 connections can result in a scratched, chipped, or dirty input connector.
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.
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. To clean the recessed end of the connector saver, insert the stick type cleaner, and rotate it server times the same direction.
