2. THEORY OF OPERATION DESIGN OF THE AMPLIFIER The Model 1000T8G18B TWT amplifier consists of five principal subsystems. From top to bottom, these are the control module (A28010-300 for 380VAC, A28010-301 for 208VAC), Supertube #1 (A28007-006), the RF combiner assembly (A28006-001), Supertube #2 (A28007-006) and the two TWT power supplies (A28013-000).
Model 1000T8G18B Since the fundamental frequencies are amplified 180° out of phase, the second harmonic products, which represent significant power in the lower part of the band, are largely in phase, and are dumped in the sum port. The residual harmonics are generally lower than –20 dBc, low enough in power that they can be blocked by a reflective filter without harm to the TWTs.
Model 1000T8G18B DESCRIPTION OF THE TWT POWER SUPPLIES The two TWT power supplies are housed in separate 19” chassis 5 rack units (8.75") high. Each power supply chassis contains a TWT power supply assembly (A22525-900), an HPA interface board (A25444-000), as well as an AC input line filter and a front panel circuit breaker.
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.
Model 1000T8G18B 3.2.2 Mounting The TWTA must be located on a nominally flat surface, and restrained so that it will not inadvertently roll out of position. The casters are not provided with brakes. Set the leveling feet when the TWTA is properly positioned for use.
Model 1000T8G18B 3.2.5 RF Connections The RF output connector is a WRD-750D24 waveguide flange. CAUTION: Never operate the TWTA without a matched output load rated for at least 1200 watts, continuous duty. The TWTA is not provided with an output isolator.

Model 1000T8G18B 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 37
Model 1000T8G18B 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.

After activating the Sleep Mode: Screen will display COOLING ON while heaters cool down. SYSTEM OFF notifies user that the amplifier is in Sleep Mode To de-Activate Sleep Mode: Press the ON soft key to de-activate Sleep Mode.

Model 1000T8G18B 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 1000T8G18B output. Do not set input drive above 0 dBm (Input drive above +13 dBm may damage the unit). The reverse power level should remain below 10% of the forward power, assuming that the load is properly matched. 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.

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.

Model 1000T8G18B 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.
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.
Model 1000T8G18B The air intake filters are the only items that require routine service. The frequency of service depends on the environment where the TWTA is used, and must be determined by inspection If there is accumulated dust on any of the air intake filters, remove them and clean them with dry compressed air.
