    Operation, Rack and Digital HPAs Fault Report Displays--Latched Faults The latched fault report displays are shown in Figure 16. Latched faults must be cleared by the operator. These fault report displays all operate in the same way. When the indicated fault occurs, the fault report display replaces the current menu and (if the audio alarm is enabled) the buzzer sounds.

  • Page 105: Initial Setup And Operation

    Operation, Rack and Digital HPAs Initial Setup and Operation General The amplifier can be operated from the amplifier Front Panel (LOCAL configuration) or from a remote controller (REMOTE configuration). The amplifier is configured at the factory with the default values shown in Table 5. These values allow immediate operation of the amplifier when the amplifier is connected to an operational load or a dummy load capable of dissipating rated RF output power.

    Note Familiarity with the XTRD menu system is required for LOCAL operation. Familiarity with the XICOM command set is required for REMOTE operation. Operating Modes The operating modes of the TWTA are described in the following sections.

  • Page 108: Standby Mode

    Operation, Rack and Digital HPAs Standby Mode In this mode, there are no faults and the TWT is ready for high voltage to be applied. Heater Standby Mode The purpose of heater standby is to extend the life to the tube when the high voltage is off.

  • Page 109: Fault Mode

    Operation, Rack and Digital HPAs Fault Mode This mode exists anytime a condition detrimental to the TWT is detected by the power supply fault detection circuitry. Faults are indicated on the front panel by red LEDs. Any of the following conditions trip the fault detection circuitry: Excessive Helix Current Fault—(Latched) When the power supply detects a Helix Current fault, it turns OFF high voltage...

  • Page 112: Normal Turn-On

    Operation, Rack and Digital HPAs 9. Turn on the RF drive signal.Slowly increase the RF drive to the TWT by rotating the Gain Control clockwise. Monitor the RF output power. Caution Do not exceed the dBm input power specification. Driving the TWT by more than 2 dBm beyond the input power required to reach the saturation point will over drive the tube.

  • Page 113: Normal Turn-Off

    Operation, Rack and Digital HPAs 3. Press the [Enable] key and the [HV ON] key at the same time. The high voltage ON indicator should light (green). This indicates that high voltage is ON and applied to the TWT. The Standby and Htr Standby Indicators should turn OFF.
