This is the equipment that switches and controls front-end part and excitation part of basic part. It switched each equipment of two methods automatically or manually. It observes the state of each equipment, and when abnormally generated, it switches automatically. Moreover, the remote control watch is possible according to the remote control device separately prepared.
It is excellent in reliability by the use of the Pin diode for SW. Moreover, the switch time has achieved 50μs or less.
The problem is not in the operation when the power supply of one method breaks down because it has synthesized the diode in the unit.
It is possible to correspond with the by-pass of the connecting cable and maintenance is easy because all interfaces and operations SW of the RF signal are output to a front panel in the emergency.
It is possible to mount on 50mm in height and space-saving.
The malfunction prevention measures have been achieved by the watch dog timer function. The latch is done as for the state of the switch equipment even though it becomes a power line failure by any chance, and broadcasting is continued as it is. Moreover in that case, the control mode “power supply off” is released.
