General Safety Considerations
General Safety Considerations
This product has been designed and tested in accordance with IEC Publication 1010, Safety Requirements for Electronic Measuring Apparatus, and has been supplied in a safe condition. The instruction documentation contains information and warnings which must be followed by the user to ensure safe operation and to maintain the product in a safe condition.
Install the instrument according to the enclosure protection provided. This instrument does not protect against the ingress of water.
This instrument protects against finger access to hazardous parts within the enclosure.
If this product is not used as specified, the protection provided by the equipment could be impaired. This product must be used in a normal condition (in which all means for protection are intact) only.
No operator serviceable parts inside. Refer servicing to qualified service personnel. To prevent electrical shock do not remove covers.
This is a Safety Class 1 Product (provided with a protective earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor inside or outside of the instrument is likely to make the instrument dangerous. Intentional interruption is prohibited.
To prevent electrical shock, disconnect the instrument from mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
Fiber-optic connectors are easily damaged when connected to dirty or damaged cables and accessories. The HP 86140 series’s front-panel INPUT connector is no exception. When you use improper cleaning and handling techniques, you risk expensive instrument repairs, damaged cables, and compromised measurements. Before you connect any fiber-optic cable to the HP 86140 series, refer to “Cleaning Connections for Accurate Measurements” on page 6-10.
This product is designed for use in Installation Category II and Pollution Degree 2 per IEC 1010 and 664 respectively.

General Safety Considerations
Do not use too much liquid in cleaning the optical spectrum analyzer. Water can enter the front-panel keyboard, damaging sensitive electronic components.
VENTILATION REQUIREMENTS: When installing the product in a cabinet, the convection into and out of the product must not be restricted. The ambient temperature (outside the cabinet) must be less than the maximum operating temperature of the product by 4° C for every 100 watts dissipated in the cabinet. If the total power dissipated in the cabinet is greater than 800 watts, then forced convection must be used.
Always use the three-prong AC power cord supplied with this instrument. Failure to ensure adequate earth grounding by not using this cord may cause instrument damage.
Do not connect ac power until you have verified the line voltage is correct as described in “Line Power Requirements” on page 1-7. Damage to the equipment could result.
This instrument has autoranging line voltage input. Be sure the supply voltage is within the specified range.

This chapter shows you how to set up your optical spectrum analyzer, connect power and accessories, and verify general operation. Although the pictures in this section show an HP 86140A or 86142A optical spectrum analyzer, setting up other HP 86140-series optical spectrum analyzers is very similar. Refer to Chapter 6, “Reference” for the following additional information:
•Tips on avoiding costly repairs by proper optical connection cleaning techniques.
•List of available options, accessories, and power cords.
•Instructions on returning your instrument to HP for service.
•HP Sales and Service Offices.

Package contents for HP 86140 series optical spectrum analyzers
Inspect the shipping container for damage.
Inspect the instrument.
Verify that you received the options and accessories you ordered.
Keep the shipping container and cushioning material until you have inspected the contents of the shipment for completeness and have checked the optical spectrum analyzer mechanically and electrically.
If anything is missing or defective, contact your nearest Hewlett-Packard Sales Office. If the shipment was damaged, contact the carrier, then contact the nearest Hewlett-Packard Sales Office. Keep the shipping materials for the carrier’s inspection. The HP Sales Office will arrange for repair or replacement at Hewlett-Packard’s option without waiting for claim settlement.
Note
The N1031A BenchLink software allows you to upload graphics and trace date to a personal computer for preparing a report, creating an analysis, or storing the waveforms for later use.

You can tilt your instrument upward for easier viewing. On the HP 86140A and 86142A instruments, lift up the front of the instrument, grasp one of the wire bails under the front corner, and pull it down and forward until it latches into place. Repeat for the other wire bail. On HP 86143A and 86145A instruments, pivot the handle to tilt the instrument.

keys and trackball, these accessories make your optical spectrum analyzer |
|
even easier to use! Connect any standard PC-compatible mouse (or other |
|
pointing device), keyboard, or external VGA-compatible display. |

HP 86140A-series optical spectrum analyzers display input light spectra from 600 nm to 1700 nm. To change instrument settings use the softkeys. To display different softkeys use these items:
•Softkey panel and softkeys
•Print, Save/Recall, System, and Application keys
•Menu bar
The menu bar or keys can be used to access the same functions. Use the trackball or an optional pointing device to make menu and softkey selections.

All displayed wavelength values show values as measured in a vacuum. This default setting can be changed to show values as measured in air. See “To change the default wavelength settings” on page 3-63 for more information.
The OPTICAL INPUT connector on standard instrument versions uses single mode fiber. Connecting multi-mode fiber to these connectors results in large reflections and insertion loss.
To ensure maximum amplitude accuracy, connect an input signal to the instrument and then press Auto Align. This starts an automatic alignment procedure that should be performed whenever the instrument has been:
•moved,
•subjected to large temperature changes, or
•warmed up at the start of each day.
Press the Auto Meas key to automatically locate the largest signal present at the input connector.
Additional software applications can be purchased and installed in your optical spectrum analyzer. These applications automate and simplify your measurement tasks. Press this key to access your applications.
