  • Page 25: Theory Of Operation

    2. THEORY OF OPERATION DESIGN OF THE AMPLIFIER The Model 1000TP8G18 TWT amplifier consists of three main parts, the microwave power assembly, the power supply, and the control. These will be described in greater detail below. The heart of the microprocessor control system is the control head assembly (A27509-301), which consists of the CPU board (A25450-000) and the data link board (A22488-013).

  • Page 26: Description Of The Power Supply (A22826-914)

    Model 1000TP8G18 panel is provided with a circuit for control head bypass in the event of a failure. In emergency bypass operation the attenuator signal is provided locally by means of a potentiometer on the emergency bypass board. RF pulsing characteristics are protected by the Pulse Monitor Board (A30750-000). This board protects the HPA from over duty and over pulse width 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 28: Mounting And Removing

    Model 1000TP8G18 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. If rack mounting is desired, first remove the module from the cabinet, then install the module in the rack. NOTE: Due to the weight of the unit, the installation or removal of the amplifier is a two-person operation.

  • Page 29: Cooling Requirements

    Model 1000TP8G18 3.2.3 Cooling Requirements The TWTA is provided with a cooling fan. It is important that air movement around the rear of the unit 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 the exhaust flow is directed into the intakes.

  • Page 30: External Interlock Connector

    Model 1000TP8G18 CAUTION: Never operate the TWTA without a matched input termination or drive source. When operating the unit with an antenna and without adequate isolation to the input, use caution in selecting well-shielded input cables and signal source. Use a 6 dB or larger pad (RF attenuator) directly at the TWTA input connector to reduce risk of “looping”...

    Model 1000TP8G18 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 33 Model 1000TP8G18 Menu screens - The screens at the highest level are called menu screens. There are five 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.

    Model 1000TP8G18 INITIAL TURN ON AND WARM-UP PROCEDURE Install the TWTA as discussed in section 3.2. Provide an RF generator to the RF input Type N connector. Set RF generator level below -50dBm and set desired frequency in specified range. Connect a load suitable for 200 watts continuous operation to the RF output.

An alternate procedure is to pre-set the TWTA gain to minimum, set the RF generator to 0 dBm and then slowly increase the TWTA gain to set the desired RF output level.

  • Page 43: 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 44 Model 1000TP8G18 Noise Power Density (NPD): TWTAs produce rf noise over their operating frequency range, as specified by the Noise Power Density (NPD). This noise is significantly higher than the noise produced by typical solid 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 –...

  • Page 45: Maintenance

    4. MAINTENANCE The TWTA requires a minimum of routine maintenance. The only moving parts are the elements of switches, relays and blowers. Preventive maintenance is recommended in Section 4.3. In the event that the TWTA needs repairs, it is recommended that the unit be returned to the factory. However, some user service organizations may choose to perform their own corrective maintenance, and under some circumstances returning the unit to the factory may be impractical.

  • Page 47: Non-Repairable Modules

    Model 1000TP8G18 The service technician should become familiar with the internal mechanical construction to permit correct re- assembly. Limited troubleshooting may be conducted, with caution, based on the failure symptom and an understanding of the logic/schematic diagrams. NON-REPAIRABLE MODULES The Heater power supply (A10010-000), the Grid modulator (A23684-101), the HV filter (A21458-010), Capacitor Bank (A21458-050) and the Diode/Cap assembly (A21425-021) are encapsulated modules and are not repairable.

  • Page 69 AR's pulse TWTAs are designed specifically for pulsed applications. They cannot be used to produce CW output. AR's TP series of pulse TWTAs do incorporate many of the excellent features of AR's T series of CW TWTAs such as: foldback protection, bright 4 line by 20 character alphanumeric display and extensive remote status and control via a GPIB (IEEE-488) interface.
  • Page 70 Delay, RF Rise and Fall time and the Pulse Input The beam is turned on and off in response to a TTL-level input (typically from an external Pulse Generator) applied to the Pulse Input Connector. A positive level (logical 1) turns on the beam. If RF had been applied to the TWTA input prior to the positive (logical 1) TTL input, the RF output would reach 90% of its final value within 300ns (Delay) with an observed RF Rise time of up to 30ns (10% to 90%).
  • Page 71 100 microseconds (1/10,000 sec.) following the beginning of the previous pulse. There is no minimum rate specification. Users should contact AR RF/Microwave Instrumentation regarding any specific requirements they may have for non-continuous pulse-stream applications with higher burst rates.
  • Page 72 Summary This Application Note has discussed some features of AR RF/Microwave Instrumentation's Pulse high power TWTAs and their unique specifications, those not commonly specified for CW rated amplifiers. A number of conditions have been defined which must be observed to obtain proper operation of these Pulse TWTAs (though TWTA design prevents damage when these conditions are exceeded).
  • Page 73 These modules are not field- repairable and should never be opened outside of AR’s Microelectronics Lab. The modules in these product lines have a security label on two sides of the modules between the housing and lid/cover. If the security label is removed and or cut, the warranty of the module will be voided.
