Abstract
An experimental system developed at the University of Ottawa to measure the fields radiated by the electrostatic discharge (ESD) spark is described. Its key features are a Tektronix 7912HB transient digitizer with 750 MHz single-shot bandwidth for voltage measurement, and a broadband time-domain electric-field sensor. The system is modeled in four parts: (1) a source of charge, (2) a spark gap, (3) a target, and (4) a voltage-transient digitizer. For a source, P. Richman's (1985) DUAL-RLC human body model was used. A zero-resistance spark gap is assumed. The target is essentially a current-to-voltage converter-typically, a distributed 2 Omega resistor. These were combined with a simple one-pole model of an oscilloscope to build a SPICE simulation model of the system. The body capacitance was set to an initial condition of 2 kV, and a transient analysis was performed to simulate the image, i.e., the displayed waveform, on the oscilloscope. A bandwidth of 750 MHz was seen to be adequate to observe both the risetime and the peak of the ESD current, given the above model parameters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
