1. HMM Discharge:
Actual HMM discharge; standing on a Teflon sheet for insulation
Subject is charged by touching high voltage supply output through a high meg charge resistor
Subject disconnects from HV supply and immediately touches metal rod in hand to ESD target in center of ground plane to discharge himself (HMM event).

2. Gun Discharge Tests:
Typical ESD gun discharge into ESD Target; Radiation measurements made with ESD Target, TEM, and Loop antennas.

3. Loop Sensors:
Large and small H field loop antennas as mounted to large ground plane.
These H-field sensors are without integrator and measure di/dt of H-field passing through it.

4. H Fields with Loop 3 (small loop, diameter 7/16”)

5. Ground Plane: Ground plane measuring 2M or 1Henry (Leo G Henry)
TEM Horn visible at upper right edge of ground plane
Power Supply and Voltmeter used for Human Charging

6. Radiation Measurements:
Comparison of Real HBM and ESD gun E-Field Radiation measured with TEM Horn
