CBA 100M-1100 Introduction
The CBA 100M-1100 is an amplier 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 amplier is designed with sufcient 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 amplier when
grounded.
The unit is powered from a switched mode power supply for high efciency,
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 amplier is
designed for rugged operation into a variety of loads. The amplier 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 amplier.
This amplier 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 supplied with 3-phase mains in star connection, a neutral line must
be supplied.
Indeltaconguration,noneutralisrequired.
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 amplier 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 amplier 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
amplier units, then the amplier input/output unit, then two further amplier
units, and nally the amplier switch unit. The amplier 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 amplier 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 amplier 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 amplier units.

11Mains input is via a pre-wired IEC 60309 3-phase plug.
Star congured supplied with a 5 pin plug.
Delta congured supplied with a 4 pin plug
If the plug requires rewiring, brown and 2 black wires are 3-phase line, blue is
neutral when used in star (unused in delta conguration) and green/yellow for
earth.
The amplier safety mechanism is a circuit breaker. The switch unit is supplied
from the power unit via the power breaker, located on the rear panel of the
power unit. Connect the cable from the switch unit to the power unit 7 pin
socket.
The remaining connectors are: RF input, RF output and BNC interlock. The use
of the interlock is optional, and the amplier will operate normally with this
connector left unterminated. If an attachment is made to the BNC interlock,
ensure that the connector is a 50 ohm type and that a high quality coaxial cable
is used for connection to the switch.
Make sure that the amplier is located in a situation with adequate ventilation.
During operation, the amplier will draw as much as 6 kVA from the mains.
Ensure that the environment of the amplier does not cause warm air from the
fans to be cycled back into the amplier.

4 operAtion
Mains switch (on amplifier switch unit)
Operating the mains switch located on the rear of the power supply unit will
apply power to the system. The amplier can now be switched on and off using
the push button located on the front panel.
Power indicator (on amplifier centre unit)
This indicator will illuminate when the mains switch is turned on, and power
is available from the mains. Indicators are also tted to the power unit and
amplier units.
Safety interlock indicator (on amplifier centre unit)
With a short circuit applied to the safety interlock connector on the rear panel,
this indicator will illuminate and the amplier gain stages will all be turned off.
The fans will continue to operate.
A short circuit applied to this connector also functions as a fault reset (see entry
under “Fault Indicator”).
Fault indicator (on amplifier centre unit)
The amplier protects itself from the following faults:
Excess module temperature
Air cooling failure (through faulty fan or blocked vent)
Partial power supply failure (loss of phase or PSU failure)
In the case of one of these faults occurring the fans will continue to operate.
The fault state is indicated by the illumination of the red fault indicator.
The behaviour of the amplier under these circumstances provides a rst level
diagnostic to the fault, as described in table 1.

RF input (rear panel of centre unit)
The RF input will accept a signal from an RF generator. This input must be within
the operating frequency range of 10 kHz to 100 MHz. An amplitude of up to 0
dBm will be sufcient to saturate the amplier. Operation outside the specied
frequency range should not be attempted, and may subject the amplier to
undue internal stress.
RF output (rear panel of centre unit)
This connector must be suitably terminated at all times during operation.
Ensure that the external N type connector, 50 ohm co-axial cable and load are
all capable of handling the power available, which can exceed 1 kW. Do not
operate the amplier without a proper termination or with defective cables or
connectors. The centre conductor of the RF output represents a severe burn
hazard to personnel.
Do not remove the output connector during operation, as
a self-sustaining arc may be struck, which will damage
theoutputconnector,andcreatearehazard.
Air inlets
The amplier units, input/output unit a power unit all depend upon a free air
supply for cooling. Ensure that the front air inlets are not restricted.
Dust can rapidly build up on the air inlets, these should be checked and cleaned
at regular intervals to ensure continued reliable operation of the amplier. Inter-
vals should not be longer than six months but may be required more often in
dusty environments.
