General Safety Considerations

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 th e user to e nsu re sa fe op er at ion an d t o maint ain the p rod uct in a safe condition.

WARNI NG If this instrument is not used as specified, the protection provided by

the equipment could be impaired. This instrument must be used in a normal condition (in which all means for protection are intact) only.

WARNI NG To prevent electrical shock, disconnect the Agilent 83434A 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.

WARNI NG This is a Safety Class 1 product (provide d 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 product is likely to make the product dangerous. Intentional interruption is prohi bited.

WARNI NG No operator serviceable parts inside. Refer servicing to qualified

personnel. To prevent electrical shock, do not remove covers.

WARNI NG For continued protection against fire hazard, replace line fuse only

with same type and ratings (5x20 mm, 1.6 A, 250 V time-delay, low breaking capacity fuse). The use of other fuses or materials is prohibited.

CAUTION This product i s designed for use in Insta llation Category II and P ollution

Degree 2 per IEC 61010- 1 and 664 respectively.

CAUTION VENTILA TION RE QUIREMENTS: When installing t he 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

iii

General Safety Considera tions

temperatur e of the product by 4°C for every 1 00 wat ts dissipated in the cabinet. If the total power dissipated in the cabinet is greater than 800 watts, then forced convection must be used.

CAUTION Always use the three-pro ng ac power cord supplied with this inst rum ent.

Failure to ensure adeq uate earth grounding by not us ing this cord may cause instrument damage .

CAUTION Do not connect ac power until you have verified the line voltage is correct as

described in Chapter 4, “Specifications and Regulatory Information”. Damage to the equipment could res ult.

CAUTION This instrument has autoranging line voltage input. Be sure the supply voltage

is within the specified range.

Measuremen t ac curacy—it’s up to you!

Fiber-optic connectors are easily damaged when connected to dirty or damaged cables and accessories. The Agilent83434A front-panel OPTICAL 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 83434A, “Fiber-Optic Connec-

tors” on page 3-8.

The Agilent 83434A—At a Glance

The Agilent 83434A 10 Gb/s lightwave receiver is designed to recover clock data and to provide linear, non-retimed data from d igitally modulated SDH/ SONET STM-64/OC-192 optic al si gn als , a s well as signals em ploying forward

error correction (FEC) at 10.664 Gb/s (option 106). The receiver is based on

an amplified PIN re c e iv er to produce a linea r ou tput with AGC stabiliz a tion. The receiver is designed to provide –16 dBm sensitivity with PRBS lengths to

–1 with BER performance of at least 1E-10.

2 The recovered clock can be used as a trigger input for the Ag il en t Infi ni iu m

DCA to allow optical eye diagram measurements when no external clock signal is available for triggering. The recovered clock also provides the required clock input for the error detector of the Agilent 71612B error performance analyzer. The non-retimed data output can be used with an er ror detector to measure and optimize BER. The output of th e re c eiver is also appropriate for eye contour and Q-factor measu re m ents.

The Agilent 83434A can be combined with the Agilent 83433A 10 Gb/s lightwave transmitter to create a complete optical link for system or fiber testing, or to form a basis for subst it ution testing of commercia l transmitters and receivers.

Step 1. Inspect the Shipment

Getting Started

Setting Up the Agilent83434A

❒ Inspect the shipping container for damage. ❒ Inspect the instrume nt. ❒ Verify that you received the 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 lightwave receiver mechanically and electrically.

The lightwave receiver is packed within a carton. Refer to “Instrume nt Ser-

vice” on page 3-18, for the descrip t ion and part numbers of the packaging

materials. Refer to “Options” on page 3-3, for th e ac ce ssor ie s shi pped wit h th e lightwave receiver.

If the shipping materials are in good condition, retain them for possible future use. You may wish to ship the lightwave receiver to another location or return it to Agilent Technologies for service. Refer to “Instrument Service ” on

page 3-18.

If anything is missing or defective, or if the lightwave rece iv er does not pass the verification test, contact your nearest Agilent Technologies Sales Office. If the shipment was damaged, contact the carrier, then contact the nearest Agi-

Step 2. Check the Fuse

Getting Started

Setting Up the Agilent83434A

1 Locate the line-input connector on the instrument’s rear panel. 2 Disconnect the line-power cable if it is connected. 3 Use a small flat-blade screwdriver to pry open the fuse holder door. 4 The fuse is housed in a small container. Insert the tip of a screwdriver on the

side of the container and gently pull outward to remove the container. A spare fuse is stored below the line fuse.

WARNI NG For continued protection against fire hazard, replace line fuse only

with same type and ratings (5 breaking capacity fuse). The use of other fuses or materials is prohibited.

Step 4. Turn on the Agilent 83434A

With the power cable inserted into the line module, turn the lightwave receiver on by pressing the line switch. The green light-emitting diode (LE D) should light.

NOTE The front panel LINE switch disconnects the mains circuits from the mains supply after

the EMC filters and before other parts of the instrument.

If the Agilent 83434A fails to turn on properly, consider the following possibilities:

❒ Is the line fuse good? ❒ Does the line socket have power? ❒ Is it plugged into the proper ac power source?

If the instrument still fail s, return i t to Agilen t Technologies for repair. Refer to

“Instrument Service” on pag e 3-18
