Figure 1 – MVG COMOHAC T-coil Probe Coil Dimension 6.55 mm length * 2.29 mm diameter DC resistance 860.6 Ω Wire size 51AWG Inductance at 1 kHz 132.1 mH at 1 kHz 3 MEASUREMENT METHOD All methods used to perform the measurements and calibrations comply with the ANSI C63.19 and IEEE 1027 standards. All measurements were performed using a Helmholtz coil built according to the specifications outlined in ANSI C63.19 and IEEE 1027. 3.1 SENSITIVITY The T-coil was positioned within the Helmholtz coil in axial orientation. Using an audio generator connected to the input of the Helmholtz coil, a known field (1 A/m) was generated within the coil and the T-coil probe reading recorded over the frequency range of 100 Hz to 1000 Hz. 3.2 LINEARITY The T-coil probe was positioned within the Helmholtz coil in axial orientation. The audio generator connected to the input of the Helmholtz coil was adjusted to obtain a field within the coil from 0 dB A/m to -50 dB A/m and the T-coil reading recorded at each power level (10 dB steps).

Figure 1 – MVG COMOHAC E field Probe Probe Length 330 mm Length of Individual Dipoles 3.3 mm Maximum external diameter 8 mm Probe Tip External Diameter 5 mm Distance between dipoles / probe extremity 3 mm 3 MEASUREMENT METHOD All methods used to perform the measurements and calibrations comply with the ANSI C63.19 and IEEE 1309 standards. 3.1 SENSITIVITY The sensitivity factors of the three dipoles were determined using the waveguide method outlined in the fore mentioned standards. 3.2 LINEARITY The linearity was determined using a standard dipole with the probe positioned 10 mm above the dipole. The input power of the dipole was adjusted from -15 to 36 dBm using a 1dB step (to cover the range 2V/m to 1000A/m).
