The TESLA 2000 was the most sophisticated disturbance recorder of its time. It used two MPBs, connected together by a bidirectional DSP-to-DSP synchronous serial link. This gave the TESLA 36 analog inputs.
However, it was the software which made the TESLA so outstanding. Although the serial port connection could be a pain to set up on MS-Windows, once it was set up, it worked like a dream. The RecordBase / RecordGraph system was amazing and intuitive. It was an instant hit in the Power Utility Community.
