S A F E T Y voltage hazard. You can learn to recognize situations that present a threat and how to avoid them. Note: The guidelines presented in this chapter are not academic. They are based on the experience of engineers and technicians who have years of experience with high voltage circuits.
Page 11 M P A H U B M O U N T c. Never work on high voltage circuits when you are alone. If anything should happen to you, your only chance may be prompt action by some other person. Be sure someone else is present and knows what to do in any emergency (e.g., how to shut equipment off, first aid, who to call, etc.) d.
Page 12 S A F E T Y i. Take personal responsibility to assure that no one can turn on the high voltage circuits when you are working on the equipment. Precautions would include taping down (or installing keeper) on controls/circuit breakers and/or disconnecting the power source to the high voltage circuits, activating interlocks that prevent high voltage turn on, etc.
Page 13 M P A H U B M O U N T p. If you do not know how the equipment works and what the hazards associated with the equipment are in specific terms, do NOT handle the equipment. The greatest protection you can have when dealing with high voltage equipment is specific, detailed knowledge on that particular piece of equipment.
Page 14 S A F E T Y disconnecting the high voltage drive source, shorting out appropriate leads, taping down switches, and anything else you can think of to protect yourself. w. When troubleshooting a unit, assume that the switches and components are defective. You may shut off the high- voltage switch in some systems, but if the switch is defective, you would still have the high voltage on.
Page 15: Microwave Radiation
The permissible levels are quite low in comparison to the power levels of the amplifiers built by CPI (e.g., less than 10 milliwatts vs. 20 to 10,000 Watts delivered by different units) Local radiation levels can be detected with the proper equipment.
Page 16: General Microwave Guidelines
General Microwave Guidelines The purpose of these guidelines is to provide practical approaches to control unwanted microwave energy associated with the operation and servicing of CPI Satcom Division equipment. The following approaches are effective in both laboratory or field environments: a.
Page 17: Chapter 1 Introduction
M P A H U B M O U N T Chapter 1 INTRODUCTION 1.1 Overview The CPI MPA (Medium Power Amplifier) Hub Mounts are designed for satellite communication earth stations, satellite news gathering vehicles, and flyaway applications. The key feature of these amplifiers permits direct mounting to antenna structures, thereby eliminating transmission line losses encountered in conventional remotely mounted arrangements.
Page 18: Figure 1-1. Mpa Hub Mount
The MPAs can be operated in either local or remote mode, the latter being the primary mode of operation. Remote operation is performed using either a CPI Remote Control Unit or a user- supplied IBM compatible computer. The RF Block diagram is shown in Figure 1-2.

Page 64: Post
O P E R A T I O N Each operating state is described in greater detail in the following text. 5.6.1 POST The microprocessor-based controller performs a list of tests that establish its ability to control and monitor the amplifier. Some areas covered by POST include checking validity of information in the battery-backed RAM, EPROM checksum, and other controller specific aspects.
Page 65: Standby State
M P A H U B M O U N T 5.6.3 Standby State The STANDBY state is the normal beam-off state. During STANDBY, high voltage is off and the unit does not amplify the RF input drive signal. While the unit is in the STANDBY state, the STBY LED is lit. After the beam is off for one minute, the Heater Reduce command is activated.
