Introduction
The ETS-Lindgren Model 8000-014 RF Power Amplifier is capable of supplying a minimum of 200 watts into a 50 ohm load over the frequency range 10kHz to 250MHz. The amplifier is designed with sufficient gain so 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 by a switched-mode power supply for high efficiency, high power factor, and a 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 fault indicator is provided to indicate over-temperature. The amplifier is designed for rugged operation into a variety of loads and is primarily intended for use as an RF 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.
Standard Configuration
- The 8000-014 amplifier is supplied for installation into a 19-inch rack.
- The RF connectors are N type female which are located on the rear panel of the amplifier.

Safety Information
- This RF amplifier has been designed and tested in accordance with BS EN61010-1 and has been supplied in a safe condition. This manual contains warning information 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 in a rack are below 85dBA as required by EN61010-1.
- If local regulations have a lower limit, appropriate action should be taken in line with the local regulations so as to comply.
- This apparatus is of Installation Category 2.
Warnings
- WARNING: 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 use of suitably rated mains cords must only be used as specified within this document, see Rear Panel, Mains Input on Page 15.
- 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 only be serviced by qualified service personnel and 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 are prohibited.
Installation
CAUTION: Before connecting any components, follow the information provided in Before You Begin on page 13.
Mains Input
- Mains input is via a 10A power cable (supplied).
- Access for mains disconnection must be maintained at all times.
Amplifier Protection
- The amplifier is protected by a fuse of the following rating, T 10A H 250V 20mm.
- This instrument must be earthed.
WARNING: If the rack mounting option has been selected, the unit must be installed in the rack using a suitable tray or runners. The amplifier must not be supported only by the front panels.
- CAUTION: Before placing into operation, follow the information provided in Before You Begin on page 13.
- Note: Make sure you are satisfied with the contents and condition of your amplifier prior to placing it into operation.
- Warning: Avoid exceeding the stated maximum input level as this can cause a risk of damaging the equipment.
- Warning: There is a significant risk of an electrical or burn hazard; to avoid this, always ensure the output is terminated into a suitable load prior to switching on the equipment.
Equipment Use
- The equipment must only be used for its intended purpose.
- All parts of the equipment must remain connected to ensure that protective circuits operate. Disconnecting parts of the equipment may impair operation and safety.
Mains Switch
- The amplifier is switched on or off by pressing the mains switch on the rear panel of the amplifier. Standby/Operate Switch (Centre Unit) Pressing the standby/operate switch toggles the state of the amplifier between Standby and Operate modes. The blue halo indicator flashes in Standby mode, whereas steady blue indicates Operate mode.
Fault Indicator (Red LED)
Should a fault be detected, the red LED on the amplifier front panel will be illuminated. The amplifier will be forced into standby mode and the unit will cease to function. This action is latching, therefore only when the fault has been cleared can the amplifier be reset; this is done by pressing the standby/operate switch.
The reasons for the system fault light to illuminate are as follows:
- Excess module temperature
- Air cooling failure (fans failing to operate)
Interlock Indicator (Orange LED)
When the rear panel interlock is activated the interlock indicator will illuminate and the amplifier gain stages will all be turned off. This action is latching; therefore, the amplifier will return to Standby mode when the interlock is released.
Local Lockout Indicator
Refer to the separate Remote Control Interface manual supplied.
RF Input (Rear Panel Mounted)
The RF input will accept a signal from an RF generator. This input must be within the operating frequency range of the 8000-014 amplifier. An amplitude of up to 0dBm will be sufficient to saturate the amplifier. Operation outside the specified frequency range should not be attempted as it may subject the amplifier to undue internal stress.
RF Output (Rear Panel Mounted)
- WARNING: The centre conductor of the RF output represents a severe burn hazard to personnel.
- Never operate the amplifier without a proper termination or with defective cables or connectors.
This connector must be suitably terminated at all times during operation. Ensure that the cable is capable of handling the power available, which may be as much as 350 watts.
Air Inlet
This amplifier requires a free air supply for cooling; the front air inlet must not be restricted.
Safety Interlock
- A dual interlock system can be operated by applying either a short circuit (S/C) or open circuit (O/C) to mute the amplifier.
- In order for the amplifier to operate, the Interlock BNC connector must be S/C and the Interlock must be O/C. If the Interlock is O/C or the Interlock is S/C the amplifier will be muted.
- The amplifier is delivered without the interlock applied and will be ready to operate.
- The interlock function is latching so when the interlock is removed the amplifier will be in standby mode. Press the standby/operate switch to return to normal operation.
- Current drawn from the interlock BNC connectors under short circuit conditions will typically be 2.8mA.
Fan Outlet
This amplifier requires a free air supply for cooling; the rear air outlets must not be restricted.
