This chapter introduces the features of the Agilent 8163A/B Lightwave
Multimeter, the Agilent 8164A/B Lightwave Measurement System, and
the Agilent 8166A/B Lightwave Multichannel System. Here you will find a
quick description of the instrument, how to use the user interface and how
to perform a simple sample session
The central element of the instrument is the Agilent 8163A/B Lightwave
Multimeter, the Agilent 8164A/B Lightwave Measurement System, and
the Agilent 8166A/B Lightwave Multichannel System mainframes. You
customize the instrument using plug-in modules and changeable fiberconnector interfaces. You can use this instrument as a tunable laser
source and also to take associated measurements.

Safety Considerations
The following general safety precautions must be observed during all
phases of operation, service, and repair of this instrument. Failure to
comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards of design, manufacture, and intended
use of the instrument. Agilent Technologies Inc. assumes no liability for
the customer’s failure to comply with these requirements.
This product has been designed and tested in accordance with IEC
Publication 61010-1, Safety Requirements for Electrical Equipment for
Measurement, Control and Laboratory. Use, and has been supplied in a
safe condition. The instruction 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.
Safety Symbols
CAUTION
WARNING
The caution sign denotes a hazard. It calls attention to a procedure
which, if not correctly performed or adhered to, could result in
damage to or destruction of the product. Do not proceed beyond a
caution sign until the indicated conditions are fully understood and
met.
The warning sign denotes a hazard. It calls attention to a
procedure which, if not correctly performed or adhered to, could
result in injury or loss of life. Do not proceed beyond a warning
sign until the indicated conditions are fully understood and met.

Getting Started Safety Considerations
General
This is a Safety Class 1 instrument (provided with a protective earth
terminal) and has been manufactured and tested according to
international safety standards.
Before operation, you should review the instrument and manual for safety
markings and instructions. You must follow these to ensure safe operation
and to maintain the instrument in safe condition.
Some Agilent 8164B circuits and some Agilent 8166B circuits are powered
whenever the instrument is connected to the AC power source. To
disconnect from the line power, disconnect the power cord either at the
rear power inlet or at the AC line power source (receptacle). One of these
must always be accessible. If the instrument is in a cabinet, it must be
disconnected from the line power by the system’s line power switch.
WARNING
WARNING
To avoid hazardous electrical shock, do not perform electrical
tests when there are signs of shipping damage to any portion of
the outer enclosure (covers, panels, and so on).
Operating Environment
The Agilent 8163A/B Lightwave Multimeter, Agilent 8164A/B
Lightwave Measurement System, and Agilent 8166A/B Lightwave
Multichannel System are not designed for outdoor use. To prevent
potential fire or shock hazard, do not expose the instrument to rain
or other excessive moisture.

CAUTION
CAUTION
CAUTION
The Agilent 8163A/B Lightwave Multimeter System complies with
overvoltage category II and can operate from the single-phase AC
power source that supplies between 100 V and 240 V at a frequency
in the range 50 to 60 Hz.The maximum power consumption is 120 VA
with all options installed.
The Agilent 8164A/B Lightwave Measurement System complies
with overvoltage category II and can operate from any single-phase
AC power source that supplies between 100 V and 240 V at a
frequency in the range from 50 to 60 Hz. The maximum power
consumption is 270 VA with all options installed.
The Agilent 8166A/B Lightwave Multichannel System complies
with overvoltage category II and can operate from any single-phase
AC power source that supplies between 100 V and 240 V at a
frequency in the range from 50 to 60 Hz. The maximum power
consumption is 450 VA with all options installed.
Input/Output Signals
CAUTION
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Sixth Edition 27
There are two input BNC connectors: the Remote Interlock
Connector and the Trigger Input, see “Input and Output Connectors”
on page 310. These are TTL inputs. A maximum of 5 V can be applied
as an external voltage to either of these input connectors.
There is one output BNC connector: the Trigger Output, see “Input
and Output Connectors” on page 310. This is a TTL output. Do not
apply an external voltage to this connector.
Getting Started Safety Considerations
Line Power Connectors
In accordance with international safety standards, the instrument has a
three-wire power cable. When connected to an appropriate AC power
receptacle, this cable earths the instrument cabinet. The type of power
cable shipped with each instrument depends on the country of destination.
Please refer to “Accessories” on page 319 for the part numbers of
available power cables.
WARNING
To avoid the possibility of injury or death, you must observe the
following precautions before switching on the instrument.
• Insert the power cable plug only into a socket outlet provided
with a protective earth contact. Do not negate this protective
action by the using an extension cord without a protective
conductor.
• Do not interrupt the protective earth connection intentionally.
• Do not remove protective covers. Operating personnel must not
remove instrument covers. Component replacement and
internal adjustments must be made only by qualified service
personnel.
• Instruments that appear damaged or defective should be made
inoperative and secured against unintended operation until they
can be repaired by qualified service personnel.
• Defective, damaged, or malfunctioning laser sources must be
returned to an Agilent Technologies Service Center.
Do not operate the instrument in the presence of flammable gases
or fumes. Operation of any electrical instrument in such an
environment constitutes a definite safety hazard.
