Problems solved by technology

[0009] A current problem with conventional technology is the difficulty in calibrating ESD detectors
This difficulty is due to, for example, the challenge of providing reproducibility of the discharge event itself
There are additional difficulties due to the conditions imposed on the radiated electric field waveform by the material and construction of the processing point itself
Therefore, current technology is limited in its performance and suffers from at least the constraints and drawbacks described above
