General Safety Considerations
General Safety Considerations
This product has been designed and tested in accordance with the standards listed on the Man-
ufacturer’s Declaration of Conformity, and has been supplied in a safe condition. The documenta-
tion contains information and warnings that 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.

General Safety Considerations
WARNING 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.
WARNING No operator serviceable parts inside. Refer servicing to qualified service personnel. To prevent
electrical shock do not remove covers.
WARNING This is a Safety Class 1 Product (provided with protective earth). 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.
WARNING 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.
CAUTION Fiber-optic connectors are easily damaged when connected to dirty or damaged cables and
accessories. The Agilent 8614x 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
Agilent 8614x series, refer to “Cleaning Connections for Accurate Measurements” on page 6-8.
CAUTION This product complies with Overvoltage Category II and Pollution Degree 2.
CAUTION Do not use too much liquid in cleaning the optical spectrum analyzer. Water can enter the front-
panel keyboard, damaging sensitive electronic components.
CAUTION 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.
CAUTION Install the instrument so that the detachable power cord is readily identifiable and is easily reached
by the operator. The detachable power cord is the instrument disconnecting device. It disconnects
the mains circuit from the mains supply before other parts of the instrument. The front panel switch

vi
General Safety Considerations
is only a standby switch and is not a LINE switch. Alternatively, an externally installed switch or
circuit breaker (which is readily identifiable and is easily reached by the operator) may be used as
a disconnecting device.
CAUTION 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.
CAUTION Do not connect ac power until you have verified the line voltage is correct as described in “Line
Power Requirements” on page 1-10. Damage to the equipment could result.
CAUTION This instrument has autoranging line voltage input. Be sure the supply voltage is within the
specified range.
CAUTION The Agilent 8614xB contain a light source classified, according to IEC 60825-1.
CAUTION Use of controls or adjustment or performance of procedures other than those specified herein may
result in hazardous radiation exposure.

Product Overview
Product Overview
The 8614xB series of optical spectrum analyzers provide fast, accurate, and comprehensive mea-
surement capabilities for spectral analysis.
• Full-featured SCPI commands for programming instruments over LAN
• Display-off feature for making faster measurements
• Remote file saving and printing for outputting measurement results
• Filter mode for accurate and flexible measurements
• Built-in applications for accelerating test times
Filter Mode The Agilent 86146B filter mode allows single dense wavelength division multiplexing (DWDM) to
be isolated and routed to external test equipment. The filter mode capability is built-in to internal
applications to allow for fast and easy implementation of channel dropping. For Agilent 86146B
instruments, this mode also allows the ability to measure time resolve chirp (TRC).
Built-in Applications Built-in applications allow fast, repeatable measurements for WDM systems, lasers, amplifiers,
and passive components. These applications can be added through a firmware upgrade.
WDM Application
This application allows you to measure DWDM sub-system components, (such as transmission
sub-systems, optical add/drop multiplexers, and multiplexers/de-multiplexers) for parameters
such as optical signal-to-noise ratio (OSNR), channel wavelength, channel power, and span tilt.
Passive Component Test Application
This application simplifies the testing of passive components, such as filters, couplers, and isola-
tors by defining a test plan that measures parameters such as insertion and return loss, band-
width, and filter shape.
Source Test Application
This application offers automated optical source and laser characterization.
