The Agilent 83487A—At a Glance
The Agilent 83487A—At a Glance
The Agilent 83487A optical/electrical plug-in module is one of several plug-in
modules available for the Agilent 83480A, 54750A mainframes. The main features of the Agilent 83487A are:
• Integrated, calibrated optical channel.
• 2.85 GHz optical channel bandwidth and user selectable 12.4 or 20 GHz
electrical channel bandwidth.
• 750 nm to 860 nm wavelength range.
• Optical channel has 1063/1250 Mb/s datacom filters.
• 62.5/125 µm (maximum) multimode, user selectable optical input connector
option.
• Electrical measurement channel.
• Trigger channel input to the mainframe.
• 3.5 mm (m) connectors on the electrical measurement channel and trigger
channel.
• One probe power connector.
• One auxiliary power connector.
NOTE
If you wish to use the Agilent 83487A optical plug-in module in an Agilent 54750A digitizing oscilloscope, a firmware upgrade must first be installed. Order the Agilent 83480K
communications firmware kit and follow the installation instructions.
The purpose of the plug-in module is to provide measurement channels,
including sampling, for the mainframe. The plug-in module scales the input
signal, sets the bandwidth of the system, and allows the offset to be adjusted
so the signal can be viewed. The output of the plug-in module is an analog signal that is applied to the ADCs on the acquisition boards inside the mainframe.
The plug-in module also provides a trigger signal input to the time base/trigger
board inside the mainframe.
For GPIB programming information, refer to the
Programmer’s Guide
supplied with the mainframe.

Measurement Accuracy
Measurement Accuracy
To ensure that you obtain the specified accuracy, you must perform a plug-in
module vertical calibration. The calibration must also be performed when you
move a plug-in module from one slot to another, or from one mainframe to
another. Refer to Chapter 3, “Calibration Overview” for information on performing a plug-in module vertical calibration.
CAUTION
The Agilent 83487A optical/electrical plug-in module input circuitry can be
damaged when the

prevent input damage, this specified level must not be exceeded.
Measurement accuracy—it’s up to you!
Fiber-optic connectors are easily damaged when connected to dirty or damaged cables
and accessories. The Agilent 83487A optical/electrical plug-in module’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 83487A optical/electrical plug-in
module, refer to “Cleaning Connections for Accurate Measurements” on page 5-14.

WARNING
CAUTION
CAUTION
CAUTION
For continued protection against fire hazard, replace line fuse only
with same type and ratings, (type T 0.315A/250V for 100/120V
operation and 0.16A/250V for 220/240V operation). The use of other
fuses or materials is prohibited. Verify that the value of the linevoltage fuse is correct.
• For 100/120V operation, use an IEC 127 5×20 mm, 0.315 A, 250 V, Agilent
part number 2110-0449.
• For 220/240V operation, use an IEC 127 5×20 mm, 0.16 A, 250 V, Agilent
Technologies part number 2110-0448.
Before switching on this instrument, make sure that the line voltage selector
switch is set to the line voltage of the power supply and the correct fuse is
installed. Assure the supply voltage is in the specified range.
This product is designed for use in Installation Category II and Pollution
Degree 2 per IEC 1010 and 664 respectively.
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
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 not
connect ac power until you have verified the line voltage is correct.
Damage to the equipment could result.
This instrument has autoranging line voltage input. Be sure the supply voltage
is within the specified range.

General Safety Considerations
CAUTION
Electrostatic discharge (ESD) on or near input connectors can damage circuits
inside the instrument. Repair of damage due to misuse is
not
covered under
warranty. Before connecting any cable to the electrical input, momentarily
short the center and outer conductors of the cable together. Personnel should
be properly grounded, and should touch the frame of the instrument before
touching any connector.

The Agilent 83487A Optical/Electrical Plug-In Module
The Agilent 83487A Optical/Electrical Plug-In
Module
The Agilent 83487A incorporates two measurement channels, one optical and
one electrical. The electrical channel has two selectable bandwidth settings. In
the lower bandwidth mode of 12.4 GHz, oscilloscope noise performance is
excellent, while the 20 GHz mode allows greater fidelity for high speed signals.
The calibrated, integrated optical channel has over 2.85 GHz bandwidth and
allows easy, precise measurements of single-mode or multimode optical signals.
The integrated optical channel reduces electrical mismatch loss variation by
eliminating signal distorting cables and connectors associated with the use of
external receivers in order to accurately characterize optical waveforms. The
optical channel is calibrated to provide both accurate display of the received
optical waveform in optical power units and measurement of the signal’s average power. In addition, the User Cal feature provides for consistent accuracy
at any wavelength between 750 nm and 860 nm using a source and power
meter.
The Agilent 83487A also is a calibrated reference receiver that is measured to
conform to specifications for Fibre Channel (FC) 1063 and Gigabit Ethernet
for transmitter compliance testing. By pressing a front-panel key or issuing an
GPIB command, a filter is inserted or removed from the measurement channel
by a very repeatable Agilent Technologies microwave switch. The switch
removes the potential variability and the time wasted by manually inserting
and removing the filter, and maximizes measurement repeatability.
The electrical measurement channel may be used to perform measurements
on tributary electrical signals, to evaluate receiver performance in transceiver
testing, for measurements with Agilent Technologies’ wide range of external
optical receivers, or for general purpose measurements.

CAUTION
CAUTION
Cover electrical connectors to protect sensitive components from electrostatic
damage. Cover optical connectors to protect them from damage due to physical
contact or dust.
Instrument damage can result from using packaging materials other than the
original materials. Never use styrene pellets as packaging material. They do not
adequately cushion the instrument or prevent it from shifting in the carton.
They may also cause instrument damage by generating static electricity.
3
Pack the instrument in the original shipping containers. Original materials are
available through any Agilent Technologies office. Or, use the following
guidelines:
• Wrap the instrument in antistatic plastic to reduce the possibility of damage
caused by electrostatic discharge.
• For instruments weighing less than 54 kg (120 lb), use a double-walled, cor-
rugated cardboard carton of 159 kg (350 lb) test strength.
• The carton must be large enough to allow approximately 7 cm (3 inches) on
all sides of the instrument for packing material, and strong enough to accommodate the weight of the instrument.
• Surround the equipment with approximately 7 cm (3 inches) of packing ma-
terial, to protect the instrument and prevent it from moving in the carton. If
packing foam is not available, the best alternative is S.D-240 Air Cap™ from
