  • Page 21: Theory Of Operation

    2. THEORY OF OPERATION DESIGN OF THE AMPLIFIER The Model 500T8G18 TWT amplifier consists of two packages, the supertube and the power supply/control module. The power supply/control module, in turn, consists of three subsystems. Two of these subsystems, the microwave components and the TWT power supply, are discussed in sections 2.2 and 2.3, respectively. The third subsystem is the microprocessor control system.

  • Page 22: Description Of The Power Supply

    Model 500T8G18 potentiometer on the emergency bypass board. However, the foldback circuit remains on line in emergency bypass operation. DESCRIPTION OF THE POWER SUPPLY The three phase version (A22525-313) is described. The TWT power supply provides cathode, heater, grid, and collector power for both tubes in the supertube assembly. The power supply is of modular construction. Low voltage power for logic and control of the entire power supply assembly is provided by the low voltage power supply module (A26452-000).

  • Page 23: Operation

    3. OPERATION WARNINGS AND CAUTIONS Throughout this manual, the symbol: WARNING: indicates that a hazard exists that may result in personal injury or loss of life. CAUTION: indicates that failure to follow procedures may result in damage to the equipment. WARNING: DANGER - High Voltage Present: Electrical equipment in this TWTA generates and stores high-voltage energy that can result in fatal electrocution.

  • Page 24: Mounting And Removing

    Model 500T8G18 3.2.2 Mounting and Removing The TWTA may be operated as a standalone benchtop unit, or it may be installed in a 19" rack. When the amplifier is rack-mounted, it is strongly recommended that the supertube module be mounted above the power supply/control module, so that the power supply will not draw in the hot air exiting the TWT cooling ducts of the supertube module.

  • Page 25: Interconnecting Cables

    Model 500T8G18 3.2.3 Interconnecting Cables Proper installation of the two interconnecting cables is essential for proper operation of the amplifier. Failure to install the cables correctly will result in failure of the unit to operate. Table 3-1 lists the interconnecting cables, and Figure 3.2 shows them pictorially.

  • Page 26: Cooling Requirements

    Model 500T8G18 3.2.4 Cooling Requirements The power supply/control module is provided with a single high-speed blower, and the supertube assembly has two identical high-speed blowers. It is important that air movement around the rear of the units be unobstructed. CAUTION: For either bench or rack mounting, do not position the TWTA in such a way that the air intakes or outlets are blocked, or that exhaust flow is directed into one of the intakes.

  • Page 27: Rf Output Connections

    Model 500T8G18 Color Function International Harmonized North American Brown Black Line Blue White Neutral Yellow/Green Green Safety Ground CAUTION: Connect plug to J1 and secure plug with bracket only when no AC is supplied to the cord. 3.2.6 RF Output Connections The RF output connector is type WRD-750 waveguide.
  • Page 28 Model 500T8G18 CAUTION: Do not rely on the external interlock for personnel protection. The intent of the external interlock feature is to disable the RF output for equipment protection. Use proper operating and safety procedures such as shutting off and unplugging the TWTA to ensure that power is removed for personnel safety.

  • Page 30: Front Panel Display And Soft Keys

    Model 500T8G18 FRONT PANEL DISPLAY AND SOFT KEYS The purpose of the front panel display is to permit the operator to access extensive information about the condition and operation of the TWTA. To accomplish this, a number of informational screens are programmed.
  • Page 31 Model 500T8G18 Menu screens - The screens at the highest level are called menu screens. There are four menu screens. At power on, the MENU 1 screen is displayed. Each of the menu screens has the soft key S4 labeled MORE. The MORE key (S4) causes the next menu screen to appear.
  • Page 32 Model 500T8G18 To activate Sleep Mode locally: Press the MORE soft key to get to MENU 2. At MENU 2 press the SETUP soft key to get to SETUP 1. At SETUP 1 press SET to activate Sleep Mode (turn heater and fan off). The system will ask Are you sure? Press SET again.
  • Page 33 Model 500T8G18 Event Screen - From MENU 4, S2 (labeled EVENT) provides a display of events logged by the control system. These events include AC power-up, heater warm-up, change from standby to operate, faults, and resets. The events are stored in a first-in-first-out (FIFO) software buffer that has room for 100 events; as new events are logged, the older ones are discarded.

    Model 500T8G18 REMOTE IEEE-488 OPERATION The TWTA is provided with a communication interface that conforms electrically to the IEEE-488 standard. It permits remote emulation of OPERATE, STANDBY, and RESET push-buttons as well as access to parameter measurements, system faults, gain adjustment, and control unit status. The following tables summarize the commands and the return codes.

  • Page 42: Twta General Considerations

    Cooling during Operate Mode: AR TWTAs have their air outlets and inlets on the rear panels. It is important to prevent the heated air, which is expelled from the TWTA’s air outlets, from being recycled into the air inlets.
  • Page 43 Model 500T8G18 state amplifiers, and is inherent in present TWTAs. The noise may surprise users new to TWTAs when it accumulates and results in a significant indication in a broadband measurement device – such as a power meter or field probe. The error produced by this indication is not significant when operating near rated TWTA power levels, but may cause difficulty when trying to operate high power TWTAs at low output power levels..

  • Page 45: Maintenance

    4. MAINTENANCE The TWTA does not require routine scheduled maintenance. The only moving parts are the elements of switches, relays and the blowers. Preventive maintenance is recommended in Paragraph 4.3. The TWTA should be repaired by a factory-authorized representative. However, since limited logic schematics and partial parts information is supplied in this manual (Section V), some user service organizations may choose to perform their own corrective maintenance.

  • Page 46: Troubleshooting

    Model 500T8G18 To open the enclosure: 1. Remove the units from the cabinet or rack as follows: NOTE: Due to the weight of the unit, the removal of the amplifier from the cabinet or rack is a two person operation. 2.
