Page 5: Introduction
1. INTRODUCTION About this manual ♦CAUTION! This Operation Manual contains important information for the user of the amplifier. It details important safety information and hazards that can be encountered by the user, and recommends precautions that should be taken to prevent damage to the amplifier or associated equipment. -
Page 6: Safety
2. SAFETY General The amplifier described in this manual is designed to be used only by qualified personnel. Use of the amplifier in a manner not specified in this manual may impair the protection provided by the amplifier. Before use, inspect the amplifier for damage which may impair safety. -
Page 7: Safety Precautions
Safety precautions Observe all the following precautions to ensure personal safety and prevent damage to the amplifier or equipment connected to it. ♦WARNING! Properly dispose of the amplifier. The RF amplifier modules in this equipment contain Beryllium Oxide, and other components contain PTFE. - Page 8 ♦CAUTION! Avoid static discharges The RF input and output connections are static-sensitive and should not be subjected to static discharge. ♦CAUTION! Use the correct line supply source It is essential that the amplifier operates from a line supply source that does not apply voltages and frequencies between the line supply conductors (or between either line supply conductor and ground) that are outside the range detailed in the specification sheet.

Page 9: Installation
3. INSTALLATION General ♦CAUTION! Exercise care when lifting. Amplifier models that are very heavy have a caution label on the top cover. Appropriate lifting practices should be observed during transportation, installation, or removal of the amplifier from its mounting position. When mounted in a rack, the amplifier must not be supported by the front panel fixing holes alone. -
Page 10: Connecting The Line Cord
Connecting the line cord ♦CAUTION! It is essential that the amplifier operates from a line source that does not apply voltages and frequencies between the line conductors (or between either line conductor and ground) that are outside the range detailed in the specification sheet. -
Page 11: Protection Circuits
If you do not need this function, fit the supplied BNC shorting-link in place. Failure to do this will result in the amplifier latching in an “Interlock Open” status which switches the amplifier into standby mode. 4. PROTECTION CIRCUITS Over Heat Protection The AS series amplifier sub components produce heat and are air cooled by fans. -
Page 12: Amplifier Operation
5. AMPLIFIER OPERATION ♦CAUTION! Ensure that all the installation procedures detailed in Section 3 are complete before operating the amplifier. ♦CAUTION! Ensure that before connecting or turning the RF source ON, the input-source peak output level is set to less than the maximum level detailed adjacent to the RF input connector(s). -
Page 13: Cooling Fan Operation
General When the front panel rocker switch is switched Up to the, “ON” position the Milmega splash screen will appear on the touch screen display. The amplifier will remain in this state for a maximum of 45 seconds while the amplifier controller completes its boot sequence. -
Page 14: Reset
Reset The “Reset” button will illuminate Red when a fault is detected and the amplifier returned to standby mode. Once the fault is removed/fixed depressing the Reset button will clear the fault indication so that normal operation of the amplifier can resumed. Local When the amplifier receives a remote command the remote... -
Page 15: Gpib
GPIB The GPIB address can be changed by pressing the GPIB button. Pressing the button will cycle through the available addresses. 6. INDICATORS & FUNCTIONS General ♦Note: The front panel touch screen shows the amplifier status for both local and remote-control conditions. -
Page 16: Connections
7. CONNECTIONS General The AS series has an RF In, RF Out and a built in dual directional coupler with N-Type forward and reflected connections. These are available in two configurations, either all on the front or all on the rear of the amplifier. The AS series are equipped with either a N-Type or a 7/16 RF output connecter (model dependent, see applicable datasheet) but the same standard shall still apply;... -
Page 17: Rf Output N-Type Or 7/16 (Model Dependent)
RF output N-Type or 7/16 (Model Dependent) ♦WARNING! High RF voltages can occur on the inner conductor of the RF-out connector, which could cause RF burns if touched. Do not expose the centre pin to static discharge. The nominal RF output impedance of the amplifier is 50 ohms, but it will safely drive a load with an input impedance other than 50 ohms (resistive or reactive), but will deliver less power. -
Page 18: Line Supply Input Connector
Line supply input connector The As series amplifier power supply is equipped with a IEC or Neutrik Powercon inlet for single phase models and a high current 3 phase, 5 wire Star configuration (184-264 VAC line to neutral) or 4 wire Delta configuration (184-264 VAC line to line) MS connector for high power models. -

Page 25: Routine Maintenance
9. ROUTINE MAINTENANCE General cleaning For cleaning the front panel, use an anti-static foam cleaner and a soft lint-free cloth or tissue. Using abrasive materials or strong solvents may damage the surface finish or the front panel overlay. RF connectors If the RF connectors are used frequently, or left disconnected for long periods, there is a tendency for dirt and oxide deposits to build up. -
Page 26: Fault Finding
• Ensure that the line circuit-breaker is not in the tripped condition. ♦Note: If the line circuit-breaker trips, there is a fault with the power supply and the amplifier must be returned to Milmega for repair. There are no user-replaceable fuses in the amplifier. -
Page 27: Fault Indications
Amplifier not responding to remote commands • Ensure that the remote connector is mated properly. • Ensure that the ‘REMOTE’ indicator is illuminated on the touch screen. If not, send a, “OPRT” command. • Ensure that there is no damage to the remote connector or cable, especially around where the cable enters the connector. - Page 28 Milmega for repair. If, after fault-finding, problems persist, contact Milmega by telephone, fax or E-mail. It may be necessary to return the equipment to Milmega for repair. See the Appendix 2 for details on how to do this.
