Control and Monitor:
All TWT voltage and current parameters are monitored at all times by a microprocessor operating at TWT cathode potential- as great as -15kv. The microprocessor protects the TWT by insuring that the voltages and currents are within limits to those stored in it's non-volatile memory. In the event of a fault, the condition that created the fault, along with the status and analog measurements of all TWT monitored voltages and currents at the time of the fault, are latched into memory until cleared by the operator. The state of the voltages and currents along with the analog readings is sent to another microprocessor operating at ground potential, which, along with information from other controls and sensors, communicates via standard RS232 interface to any external personal computer.

Documentation:

The Service Manual provided by Quarterwave on all products is exceptional. Overview, Configuration, Theory of Operation, and Modular sections provide understanding to those unfamiliar with high performance, high voltage supplies. Block Diagrams, Schematics, Circuit Descriptions, and Bills of Material are complete. Colored sections and photographs provide easy orientation and a level of sophistication not found in this industry.
