Instructions for European EMC Conformity
WARNING
It is the responsibility of the user of this equipment to provide electromagnetic shielding, filtering and isolation
which is necessary for EMC compliance to Directive 89/336/EEC. The equipment must therefor be operated in a
shielded area which provides a sufficient level of attenuation to meet the radiated emissions and immunity
specifications. All AC, DC and Control lines connected to the equipment and entering or exiting the shielded
area must have sufficient isolation to meet the conducted emissions and immunity specifications. The following
inimum levels are suggested for use in accordance with the rated power of the equipment.
m
Rated Power Minimum shielding attenuation Minimum line isolation
100 watts 50 dB 50 dB
101 - 1000 watts 60 dB 60 dB
1001 - 10,000 watts 70 dB 70 dB
Since this equipment is designed to generate high levels of Radio Frequency energy, it is also essential that the
user read and follow the “Instructions for Safe Operation” in this manual. If other equipment is operated in the
hielded room it may be disturbed by the amplifier.

ACHTUNG
Der Benutzer dieses Gerätes ist dafür verantwortlich, daß die elektromagnetische Abschirmung und Filterung
gewährleistet ist, welche gemäß Richtlinie 89/336/EEC notwendig ist. Das Gerät muß deshalb in einem
geschirmten Raum betrieben werden, welcher eine ausreichenden Schirmung bietet, um die Emissions- und
Störfestigkeitsspezifkation einzuhalten. Alle Wechsel- und Gleichspannungsleitungen sowie Steuerleitungen,
die mit dem Gerät verbunden sind und in den geschirmten Raum von außen hereingeführt werden, müssen
ausreichend gefiltert sein, um die Emissionsspezifkation einzuhalten. Es werden folgenden Minimalwerte der
chirmdämpfung und Filterung in den unterschiedlichen Leistungsklassen empfohlen.
S
Hochfrequenzleistung min. Schirmdämpfung min Filterdämpfung
100 Watt 50 dB 50 dB
101-1000 Watt 60 dB 60 dB
1001-10.000 Watt 70 dB 70 dB
Falls andere elektrische oder elektronische Geräte gleichzeitig mit dem Gerät betrieben werden, kann es zu
Beeinflussungen kommen. Da das Gerät zur Erzeugung von Hochfrequenzenergie dient ist es daher auch
nbedingt notwendig, daß der Benutzer die Sicherheitsvorschriften in der Bedienungsanleitung liest und einhält.

AVERTISSEMENT
Il est de la responsabilité de l'utilisateur de cet équipement d'assurer la protection électromagnétique, le filtrage
et l'isolation nécessaires, afin de se conformer à la directive 89/336/EEC concernant la C.E.M. Par conséquent,
cet équipement doit être mis en fonctionnement dans une enceinte d'atténuation suffisante pour satisfaire aux
spécifications d'émissivité et de susceptibilité. Toutes les alimentations alternatives, continues ainsi que les
liaisons de contrôle connectées à cet équipement, qui entrent ou sortent de cette enceinte doivent avoir une
isolation suffisante pour satisfaire aux spécifications concernant les émissions conduites et d'immunité. Pour une
utilisation conforme, les niveaux d'atténuation minimums suivants sont suggérés en fonction de la puissance de
ortie de l'équipement:
s
Puissance de sortie Atténuation minimum de l'enceinte Isolation minium de la ligne
100 Watts 50 dB 50 dB
101 à 1.000 Watts 60 dB 60 dB
1.001 à 10.000 Watts 70 dB 70 dB
Puisque cet équipement est destiné à générer de forts niveaux R.F., il est essentiel que l'utilisateur se conforme
aux instructions de sécurité indiquées dans ce manuel. Tout autre équipement en fonctionnement dans la cage de
Faraday peut-être perturbé par 1'amplificateur.

INSTRUCTIONS FOR SAFE OPERATION
BEFORE APPLYING POWER
Review this manual and become familiar with all safety
markings and instructions.
Verify that the equipment line voltage selection is
compatible with the main power source.
Protection provided by the equipment may be
impaired if used in a manner not specified by Amplifier
Research.
INTENDED PURPOSES
This equipment is intended for general laboratory use in a
wide variety of industrial and scientific applications. It is
designed to be used in the process of generating,
controlling, and measuring high levels of electromagnetic
Radio Frequency (RF) energy. Therefore, the output of the
amplifier must be connected to an appropriate load such as
an antenna or field-generating device. It is the
responsibility of the user to assure that the device is
operated in a location which will control the radiated
energy such that it will not cause injury and will not
violate regulatory levels of electromagnetic interference.
HAZARDOUS RF VOLTAGES
The RF voltages on the center pin of the RF output
connector can be hazardous. The RF output connector
should be connected to a load before AC power is applied
to the amplifier. Do not come into contact with the center
pin of the RF output connector or accessories connected to
it. Place the equipment in a non-operating condition before
disconnecting or connecting the load to the RF output
connector.
SAFETY GROUND
This equipment is provided with a protective earth
terminal. The main power source to the equipment must
supply an uninterrupted safety ground of sufficient size to
the input wiring terminals, power cord, or supplied power
cord set. The equipment MUST NOT BE USED if this
protection is impaired.
PHYSICAL DAMAGE
The RF amplifier should not be operated if there is
physical damage, missing hardware, or missing panels.
MAINTENANCE CAUTION
Adjustment, maintenance, or repair of the equipment must
be performed only by qualified personnel. Hazardous
energy may be present while protective covers are
removed from the equipment even if disconnected from
the power source. Contact may result in personal injury.
Replacement fuses are required to be of specific type and
current rating.
SAFETY SYMBOLS
This symbol is marked on the equipment
when it is necessary for the user to refer to
the manual for important safety
information.
Dangerous voltages are present. Use
extreme care.
CAUTION: The caution symbol denotes
a potential hazard. Attention must be
given to the statement to prevent damage,
destruction, or harm.
Indicates protective earth terminal.
RANGE OF ENVIRONMENTAL CONDITIONS
This equipment is designed to be safe under the following
environmental conditions:
•Indoor use
•Altitude up to 2000M
•Temperature of 5°C to 40°C
•Maximum relative humidity 80% for temperatures up
to 31°C. Decreasing linearly to 50% at 40°C.
•Main supply voltage fluctuations not to exceed ± 10%
of the nominal voltage or minimum and maximum
autoranging values.
•Pollution degree 2: Normally non-conductive with
occasional condensation. While the equipment will
not cause hazardous condition over this environmental
range, its performance may vary.
COOLING AIR
Care should be exercised not to block the cooling air inlets
or outlets. Cooling air blockage can result in damage to the
RF amplifier or intermittent shut-downs.

NOTICE
The amplifier described in this text is basically designed for operation with signal frequencies from 10 kHz to 220
MHz.
Variations in alignment and component selection will be determined by the model number ordered.
See the amplifier specification sheet for frequency range and power output. The Model 2500L is referenced
throughout the text to explain operation. The appropriate model number should be substituted for individual
amplifiers.
