  • Page 39: Maintenance

    4. MAINTENANCE GENERAL MAINTENANCE INFORMATION The Model 100A400AM20 requires very little maintenance since it is a relatively simple instrument. It is built with etched circuit wiring and solid state devices that will ensure long, trouble free life. However, should trouble occur special care must be taken in servicing to avoid damage to the devices or the etched circuit board.

  • Page 40: Troubleshooting

    GaN HEMTs, LDMOS and other ESD-sensitive devices. Troubleshooting the Model 100A400AM20 in a logical manner can speed the solution to a problem. The settings of potentiometers (pots), capacitors (caps), or other variables should not be disturbed until other problems have been eliminated.

    <0.1V when S1 is depressed. S1 is normally open; it is closed only when it is depressed. The amplifier should change state every time the POWER switch is depressed. 8. If all voltages are correct and the unit still does not operate, contact AR to arrange for repair or replacement of the A4 Control/Fault Board.

  • Page 42: The Unit Cannot Be Operated Remotely

    Interlock Fault (Schematic 10047796) The Model 100A400AM20 is equipped with an interlock connector, which is located on the rear panel. The interlock circuit can be used to sense the openings of doors to screen rooms, test chambers, and so forth, and to turn off RF energy when these doors are opened.

  • Page 43: Ps2 Fault (Schematic 10047796)

    Model 100A400AM20 4.3.5 PS2 Fault (Schematic 10047796) The PS2 power supply has DC OK output which is normally low (< 0.1V) to the A4 J13, pin 30. If any of the PS2 outputs fail, this output will go high (> 4.0V) and inhibit the A1 High Gain Amplifier.

    1. The Model 100A400AM20’s saturated power and typical gain response at -20 dBm input is shown in Figure 4-1. The actual gain may vary from that shown in Figure 4-1 but should be ≥ 50 dBm.
  • Page 45 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.
