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 informa-
tion 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 appa-
ratus 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
regulations.
This apparatus is of installation category 2.

CBA 100M-1100 User Manual
This apparatus is capable of delivering harmful levels of
radio frequency power. Ensure at all times during opera-
tion 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
andofthespeciedtypeareusedforreplacement.The
use of makeshift fuses and the short-circuiting of fuse
holders is prohibited.

CBA 100M-1100 Introduction
The CBA 100M-1100 is an amplier capable of supplying 1.1 kW into a 50 ohm
load over the frequency range 10 kHz to 100 MHz, during the course of EMC
tests on electrical equipment. The amplier is designed with sufcient 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 amplier when
grounded.
The unit is powered from a switched mode power supply for high efciency,
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
sensing.
A front panel indicator is provided to indicate over-temperature. The amplier is
designed for rugged operation into a variety of loads. The amplier 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 amplier.
This amplier 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.
Potential or theoretical hazards.

CBA 100M-1100 User Manual
Threat Precaution
Exposure of personnel to high RF elds
produced by an antenna connected to
the output of the amplier.
Ensure that the antenna is inside a
screened enclosure and t an interlock
to the entry door to prevent access
while the amplier is operating.
RF burns caused by contact with the
antenna connected to the output of
the amplier.
Ensure that the antenna is inside a
screened enclosure and t an interlock
to the entry door to prevent access
while the amplier is operating.
Amplier self oscillation caused by
feedback from un-terminated con-
nectors.
This is an unlikely but theoretical
possibility. Always ensure that the
amplier input is terminated either
by the system signal generator or by
a suitable RF load/attenuator before
switching the amplier on.
Arcing due to high RF voltages present
at the output connector.
Always ensure that the output of the
amplier is terminated either by the
system antenna or a suitable high
power RF load or attenuator.

3.1 Unpacking
The CBA 100M-1100 should contain the following items housed in a 19 inch
34 U rack:
Check that the equipment is complete as in the packing list above. If any signs
of damage are found inform Teseq and do not install or use the instrument. If
the shipping carton has been damaged, retain the shipping carton and packing
material for the inspection by the carrier.
3.2 Installation
This instrument must be earthed.

CBA 100M-1100 User Manual
If supplied with 3-phase mains in star connection, a neutral line must
be supplied.
Indeltaconguration,noneutralisrequired.
This equipment is intended for rack mounting, using suitable tray and runners
etc. The individual modules must not be mounted only by the front panels.
Typically, the amplier will be supplied ready assembled in a cabinet. However,
if supplied in separate units for shipping convenience, the assembly procedure
is as below.
Arrangement of modules in cabinet.
This amplier is supplied with a 34 U instrument rack ready for the insertion
of the modules.
The modules should be arranged with the power unit at the bottom, then two
amplier units, then the amplier input/output unit, then two further amplier
units, and nally the amplier switch unit. The amplier units are distinguished
only by the length of DC supply cable, and so should be ordered from bottom
to top such that the unit with the shortest supply cable is at the bottom, and
the unit with the longest supply cable is at the top. For convenience and ease
of assembly, a 1U spacer panel is supplied for insertion between each unit.
Cable connection
Connect the centre unit supply cable from the power unit to the centre unit.
Connect each of the amplier modules to the power unit using the connectors
and cables supplied. Connect the SMA to SMA RF cables from each of the
outputs on the centre unit, to the connectors on each of the amplier units, and
similarly for the N to N cables The order of connection is arbitrary. Connect the
BNC to BNC cables from the centre unit to each of the amplier units.
