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 regulations. This apparatus is of installation category 2. 5 6 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 User Manual 2Introduction 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 sensing. 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.

CBA 100M-400 User Manual 3Unpacking and installation 3.1 Unpacking The CBA 100M-400 package should contain: 10 kHz to 100 MHz Amplifier Power cable (UK) Power cable (USA / JAPAN) Power cable (EUROPE) Spare fuse T 10 A time delay 20 mm CBA 100M-400 Operating manual (this document) Calibration report CBA 100M-400 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. 9 10 4Operation 4.1 Front panel Mains switch Operating the mains switch will apply power to the amplifier gain stages and fan. 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. CBA 100M-400 User Manual 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 panel. Fan outlet The amplifier depends upon a free air supply for cooling. Ensure that the fan outlets are not restricted. 11 12 5Specification The following specification applies over the operational temperature and frequency range unless otherwise stated, and does not include the characteristics of connecting cables.
