1Safety Information
This apparatus has been designed and tested in accordance with BS EN 61010-1,
and has been supplied in a safe condition. This manual contains some information warnings which must be followed to ensure safe operation, and to retain
the apparatus in a safe condition.
This apparatus does not incorporate components liable to explode or implode
during normal operating conditions. In normal operating conditions this apparatus does not liberate injurious or poisonous gases.
Sound levels of this apparatus after installation in a rack are below 85 dBA,
as required by EN 61010-1. However local regulations may have a lower limit
or the system as a whole may exceed the local limit. In this case appropriate
action should be taken, ie of use of any protective equipment required by local
This apparatus is of installation category 2.
This apparatus is capable of delivering harmful levels of
radio frequency power. Ensure at all times during operation that the RF output is properly terminated with an
adequately rated termination or transducer, and that the
cables and connectors attached to the apparatus are in
good condition.
The mains plug shall only be inserted in a socket outlet
provided with a protective earth contact. The protective
action must not be negated by the use of an extension
cord without a protective conductor.
The opening of covers or removal of parts is likely to
expose live parts.
This apparatus must be disconnected from all voltage
sources before it is opened for adjustment, replacement,
maintenance or repair.
Make sure that only fuses of the required rated current
and of the specified type are used for replacement. The
use of makeshift fuses and the short-circuiting of fuse
holders is prohibited.

CBA 100M-400 Introduction
The CBA 100M-400 is an amplifier capable of supplying 400 watts into a 50
ohm load over the frequency range 10 kHz to 100 MHz, during the course of
EMC tests on electrical equipment. The amplifier is designed with sufficient
gain such that it may be used with normal output levels of signal sources. A
safety interlock on the rear panel is also provided, which will mute the amplifier
when grounded.
The unit is powered from a switched mode power supply for high efficiency,
high power factor and wide voltage range operation. The unit is air cooled with
integral fans, and is protected against faulty cooling by excess temperature
A front panel indicator is provided to indicate over-temperature. The amplifier is
designed for rugged operation into a variety of loads. The amplifier is primarily
intended for use as a power source for EMC susceptibility testing, but is also
applicable to other systems requiring a wide-band linear amplifier.
This amplifier is designated as ‘professional equipment’ and should not be
operated by untrained staff.
As this product has the capability to generate high levels of RF energy it is not
intended for use in a residential environment.

If any signs of damage are found, no attempt should be made to install the
instrument, which should be returned to Teseq or their agent. If the shipping
carton has been damaged, retain the shipping carton and packing material
for the carrier’s inspection. Check that the equipment is complete as in the
packing list above.
3.2 Installation
This instrument must be earthed.
4.1 Front panel
Mains switch
Operating the mains switch will apply power to the amplifier gain stages and
Power indicator
This indicator will illuminate when the mains switch is turned on, and power is
available from the mains.
Fault indicator
Should the amplifier be subject to a failing in the cooling system, either by a
fan failure, inadequate air supply or excess ambient temperature, this indicator
will illuminate and the amplifier gain stages will all be turned off. This action is
non-latching, so the gain stages will switch on again when the amplifier has
cooled down.
RF input (depending on model)
The RF input will accept a signal from an RF generator. This input must be
within the operating frequency range of the amplifier. An amplitude of up to 0
dBm will be sufficient to saturate the amplifier. Operation outside the specified
frequency range should not be attempted, and may subject the amplifier to
undue internal stress.
RF output (depending on model)
This connector must be suitably terminated at all times during operation. Ensure
that the cable and load are all capable of handling the power available, which
may be as much as 600 watts. On no account operate the amplifier without a
proper termination or with defective cables or connectors. The centre conductor of the rf output represents a severe burn hazard to personnel.

Air inlet
The amplifier depends upon a free air supply for cooling. Ensure that the front
air inlet is not restricted.
4.2 Rear panel
Mains input
The mains input is an IEC 60320 type. The cable attached to the mains input
must be rated at 10 A to ensure proper operation at the minimum line voltage
of 85 Vac. The fuse-holder is integral with this mains connector. Use 10 A antisurge (T).
Input/output connectors (depending on model)
The RF input and output connectors may optionally be placed on the rear
Fan outlet
The amplifier depends upon a free air supply for cooling. Ensure that the fan
outlets are not restricted.
