General Safety Considerations
This product has been designed and tested in accordance with the standards
listed on the Manufacturer’s Declaration of Conformity, and has been supplied
in a safe condition. The documentation 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.
WARNING
If t his product is not used as specified, t he prot ection provided by t he
equipment could be impaired. This product must be used in a normal
condition ( in which all means for prot ect ion are intact ) only.
WARNING
WARNING
No operat or serviceable parts inside. Refer servicing to qualified
service personnel. To prevent elect rical shock do not remove covers.
This is a Safet y Class 1 Product ( provided wit h a protective eart hing
ground incorporated in the power cord) . The mains plug shall only be
insert ed in a socket out let provided wit h a protect ive earth cont act.
Any interruption of the prot ective conductor inside or out side of the
inst rument is likely to make the instrument dangerous. Intentional
int erruption is prohibit ed.
WARNING
To prevent electrical shock, disconnect the inst rument from mains
before cleaning. Use a dry clot h or one slightly dampened wit h wat er
to clean t he external case part s. Do not at tempt t o clean int ernally.
Fiber-optic connectors are easily damaged when connected to dirty or
damaged cables and accessories. The Agilent 86140B 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 86140B series, refer to “Cleaning Connections for Accurate
Measurements” on page 6-8.

General Safety Considerations
CAUTION
CAUTION
CAUTION
This product is designed for use in Installation Category II and Pollution
Degree 2 per IEC 61010-1C and 664 respectively.
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.
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 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
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.
Do n ot connect ac power until you have verified the line voltage is correct as
described in “Line Power Requirements” on page 1-11. Damage to the
equipment could result.
CAUTION
CAUTION
CAUTION
This instrument has autoranging line voltage input. Be sure the supply voltage
is within the specified range.
The Agilent 86140B, 86141B, 86144B, 86146B and 86142B Option 004/005/006
EELED sources contain an IEC Class 1 LED, according to IEC 60825.
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 86140B series of optical spectrum analyzers provide fast, accurate, and
comprehensive measurement 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 86144B and 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 Applica tion
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.
Pa ssive Component Test Applica tion
This application simplifies the testing of passive components, such as filters,
couplers, and isolators by defining a test plan that measures parameters such
as insertion and return loss, bandwidth, and filter shape.
