Introduction

This Calibration Report reproduces the results of the calibration performed in line with the references
listed below. Calibration is performed using accepted methodologies as per the references listed
below. Probes are calibrated for air, and tissue and the values reported are the results from the
physical quantification of the probe through meteorgical practices.

Calibration Method

Probes are calibrated using the following methods.

<1000MHz
TEM Cell for sensitivity in air
Standard phantom using temperature transfer method for sensitivity in tissue

>1000MHz
Waveguide* method to determine sensitivity in air and tissue
*Waveguide is numerically (simulation) assessed to determine the field distribution and power

The boundary effect for the probe is assessed using a standard flat phantom where the probe output
is compared against a numerically simulated series of data points

Boundary Effect:

Uncertainty resulting from the boundary effect is less than 2.1% for the distance between the tip of
the probe and the tissue boundary, when less than 0.58mm.


Spatial Resolution:

The spatial resolution uncertainty is less than 1.5% for 4.9mm diameter probe.
The spatial resolution uncertainty is less than 1.0% for 2.5mm diameter probe.

DAQ-PAQ Contribution

To minimize the uncertainty calculation all tissue sensitivity values were calculated using a load
impedance of 5 MΩ.

Boundary Effect:

For a distance of 0.58mm the worst case evaluated uncertainty (increase in the probe sensitivity) is
less than 2.1%.

NOTES:

*The maximum deviation from the centre frequency when comparing the lower to upper range is
listed.

**The 1900MHz body calibration had an assessed deviation of +8.52%. This value has been
normalized to be within 1.4% assessed deviation. As the deviation measured would have contributed
to a higher SAR value APREL can conclude that SAR measurements made with this probe will have
been within typical uncertainty of 10% and that this would not contribute to SAR value which if
corrected would yield a higher than reported value.
