conjunction with the Agile nt 8510 network analyzer manual set. Th ese
manuals provide the inform ation needed to properly configure your system
and make measurements.
NOTE The 8511B manual may be inserted into the 8510 test sets and accessories
binder that was provided with your 8510 manual set.
The 8511B Operating portion consists of:
• General Information
• Specifications
• Installation
• Operation
• Performance Tests
The 8511B Service portion consists of:
• Troubleshooting
• Replacement procedure s
• Replaceable parts
First. Read the chapters titled “General Information” and “Installation.”
These chapters include information on site preparation, unpacking and
inspecting your instr ument for damage, safety considerations, and
configuring your test set to the 8510.
Second. Read the chapters of the Agi lent 85056 Calibr ation Kit Manual, that
pertain to the care, cleaning, gaging, and connection of precision 2.4 mm
devices. This information wil l help you make good connec tions and care for
your precision devices, and to maintain the performance of your test set and
network analyzer system.
Third. Read the chapter titled “Operation.” This chapter will acquaint you
with the front and rear panel features of your test set. Also included is
information on control ling mu ltiple test sets, using the anti-rotation clamps,
and connecting devices to the test set.

Verifying the Agilent 8511B
Verifyi ng the A gil ent 8511B
The Agilent 8511B has been designed to operate specifically with the 8510
network analyzer.
• To install the instrument, turn to Chapter 3, “Installation”.
• To verify that the instrument meets its published specifications, use the
Agilent 8511A,B and Antenna Measurement System Performance
Verification Software (part number 08511-60024).
• To troubleshoot the test se t, refer to the troubleshooting information in
the Agilent 8510 On-Site Service Manual. This will determine if the test
set is at fault. Then refer to Chapter 6, “Test Set Troubleshooting” for
more information.

Measurement Accuracy
Measurement Accuracy
Any precision measure ment is no bet ter than the calibration of the netw ork
analyzer. As a ge neral rule , the sh orter t he time between a c alibr ation and the
measurement of a devi ce unde r test (DUT), the more precise the
measurement will be, within the limitations of your system. For this r eason,
Agilent recom mends that for prec ision measurements you recalibrate your
system every few hours, or at a minimum, reverify your system calibration.
The frequency of your requ ir ed calibration will depend on the temperature
stability of the location of the network analyzer.

Instrument Compatibility
The Agilent 8511B is compatible with all 8510 network analyzers. Agilent
836XX-series sources must ha ve a frequency range that extends to 50 GHz
to take full advantage of the frequency range of the 8511B. If your network
analyzer and/or source do not fulfill the required conditions, it will be
necessary to upgrade your syste m. Plea se consult your Agilent
representative for more information.

Electrostatic Discharge Information
Electrostati c discha rge (ESD) ca n damage or destr oy e lect ronic compone nts.
All work on electronic assemblies should be performed at a static-safe work
station. Figure 1-3 sho ws an exa mple of a stati c-safe w ork sta tion using ESD
protection. When used properly, this provides a signifi cant level of ESD
protection.
To ensure user safety, the static-safe accessories must provide at least 1 M
of isolation fr om ground. Refer to Ta ble 1-1 on page 1-13 for information on
ordering static- safe accessories.
WARNING These techniques for a static-safe work stat ion should not be used when
working on circuitry with a voltage potential greater than 500 volts.

Reducing ESD Damage
The followin g suggestions may help reduce the ESD damage that occurs
during testing and servicing operations.
• Before connecting any coaxial cable to an instrument connector for the
first t ime each day, momentarily gr ound the center and oute r conductors
of the cable.
• Personnel should be gr ounded with a resistor -isolated wrist-strap before
touching the center pin of an y connec tor and before removing any
assembly from the unit.
• Be sure that all instruments are properly earth-grounded to pre vent a
buildup of static charge.
Table 1-1 lists static-safe acc essories that can be obtaine d from Agilent using
the part numbers shown.
