PRODUCT DESCRIPTION
2.1
GENERAL INFORMATION
MVG’s COMOSAR E field Probes are built in accordance to the IEEE 1528, OET 65 Bulletin C and
CEI/IEC 62209 standards.

MEASUREMENT METHOD
The IEEE 1528, OET 65 Bulletin C, CENELEC EN50361 and CEI/IEC 62209 standards provide
recommended practices for the probe calibrations, including the performance characteristics of
interest and methods by which to assess their affect. All calibrations / measurements performed meet
the fore mentioned standards.
3.1
LINEARITY
The evaluation of the linearity was done in free space using the waveguide, performing a power
sweep to cover the SAR range 0.01W/kg to 100W/kg.

COMOSAR E-FIELD PROBE CALIBRATION REPORT
3.2
SENSITIVITY
The sensitivity factors of the three dipoles were determined using a two step calibration method (air
and tissue simulating liquid) using waveguides as outlined in the standards.
3.3
LOWER DETECTION LIMIT
The lower detection limit was assessed using the same measurement set up as used for the linearity
measurement. The required lower detection limit is 10 mW/kg.
3.4
ISOTROPY
The axial isotropy was evaluated by exposing the probe to a reference wave from a standard dipole
with the dipole mounted under the flat phantom in the test configuration suggested for system
validations and checks. The probe was rotated along its main axis from 0 - 360 degrees in 15 degree
steps. The hemispherical isotropy is determined by inserting the probe in a thin plastic box filled
with tissue-equivalent liquid, with the plastic box illuminated with the fields from a half wave dipole.
The dipole is rotated about its axis (0°–180°) in 15° increments. At each step the probe is rotated
about its axis (0°–360°).
3.5
BOUNDARY EFFECT
The boundary effect is defined as the deviation between the SAR measured data and the expected
exponential decay in the liquid when the probe is oriented normal to the interface. To evaluate this
effect, the liquid filled flat phantom is exposed to fields from either a reference dipole or waveguide.
With the probe normal to the phantom surface, the peak spatial average SAR is measured and
compared to the analytical value at the surface.
MEASUREMENT UNCERTAINTY
The guidelines outlined in the IEEE 1528, OET 65 Bulletin C, CENELEC EN50361 and CEI/IEC
62209 standards were followed to generate the measurement uncertainty associated with an E-field
probe calibration using the waveguide technique. All uncertainties listed below represent an
expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor
of k=2, traceable to the Internationally Accepted Guides to Measurement Uncertainty.

MEASUREMENT METHOD
The IEEE 1528, OET 65 Bulletin C and CEI/IEC 62209 standards provide requirements for
reference dipoles used for system validation measurements. The following measurements were
performed to verify that the product complies with the fore mentioned standards.
4.1
RETURN LOSS REQUIREMENTS
The dipole used for SAR system validation measurements and checks must have a return loss of -20
dB or better. The return loss measurement shall be performed against a liquid filled flat phantom,
with the phantom constucted as outlined in the fore mentioned standards.
4.2
MECHANICAL REQUIREMENTS
The IEEE Std. 1528 and CEI/IEC 62209 standards specify the mechanical components and
dimensions of the validation dipoles, with the dimensions frequency and phantom shell thickness
dependent. The COMOSAR test bench employs a 2 mm phantom shell thickness therefore the
dipoles sold for use with the COMOSAR test bench comply with the requirements set forth for a 2
mm phantom shell thickness.

MEASUREMENT METHOD
The IEEE 1528, OET 65 Bulletin C and CEI/IEC 62209 standards provide requirements for
reference dipoles used for system validation measurements. The following measurements were
performed to verify that the product complies with the fore mentioned standards.
4.1
RETURN LOSS REQUIREMENTS
The dipole used for SAR system validation measurements and checks must have a return loss of -20
dB or better. The return loss measurement shall be performed against a liquid filled flat phantom,
with the phantom constucted as outlined in the fore mentioned standards.
4.2
MECHANICAL REQUIREMENTS
The IEEE Std. 1528 and CEI/IEC 62209 standards specify the mechanical components and
dimensions of the validation dipoles, with the dimensions frequency and phantom shell thickness
dependent. The COMOSAR test bench employs a 2 mm phantom shell thickness therefore the
dipoles sold for use with the COMOSAR test bench comply with the requirements set forth for a 2
mm phantom shell thickness.
MEASUREMENT UNCERTAINTY
All uncertainties listed below represent an expanded uncertainty expressed at approximately the 95%
confidence level using a coverage factor of k=2, traceable to the Internationally Accepted Guides to
Measurement Uncertainty.

SAR REFERENCE DIPOLE CALIBRATION REPORT
MEASUREMENT METHOD
The IEEE 1528, OET 65 Bulletin C and CEI/IEC 62209 standards provide requirements for
reference dipoles used for system validation measurements. The following measurements were
performed to verify that the product complies with the fore mentioned standards.
4.1
RETURN LOSS REQUIREMENTS
The dipole used for SAR system validation measurements and checks must have a return loss of -20
dB or better. The return loss measurement shall be performed against a liquid filled flat phantom,
with the phantom constucted as outlined in the fore mentioned standards.
4.2
MECHANICAL REQUIREMENTS
The IEEE Std. 1528 and CEI/IEC 62209 standards specify the mechanical components and
dimensions of the validation dipoles, with the dimensions frequency and phantom shell thickness
dependent. The COMOSAR test bench employs a 2 mm phantom shell thickness therefore the
dipoles sold for use with the COMOSAR test bench comply with the requirements set forth for a 2
mm phantom shell thickness.
MEASUREMENT UNCERTAINTY
All uncertainties listed below represent an expanded uncertainty expressed at approximately the 95%
confidence level using a coverage factor of k=2, traceable to the Internationally Accepted Guides to
Measurement Uncertainty.

VALIDATION MEASUREMENT
The IEEE Std. 1528, OET 65 Bulletin C and CEI/IEC 62209 standards state that the system
validation measurements must be performed using a reference dipole meeting the fore mentioned
return loss and mechanical dimension requirements. The validation measurement must be performed
against a liquid filled flat phantom, with the phantom constructed as outlined in the fore mentioned
standards. Per the standards, the dipole shall be positioned below the bottom of the phantom, with
the dipole length centered and parallel to the longest dimension of the flat phantom, with the top
surface of the dipole at the described distance from the bottom surface of the phantom.

MEASUREMENT METHOD
The IEEE 1528, OET 65 Bulletin C and CEI/IEC 62209 standards provide requirements for
reference dipoles used for system validation measurements. The following measurements were
performed to verify that the product complies with the fore mentioned standards.
4.1
RETURN LOSS REQUIREMENTS
The dipole used for SAR system validation measurements and checks must have a return loss of -20
dB or better. The return loss measurement shall be performed against a liquid filled flat phantom,
with the phantom constucted as outlined in the fore mentioned standards.
4.2
MECHANICAL REQUIREMENTS
The IEEE Std. 1528 and CEI/IEC 62209 standards specify the mechanical components and
dimensions of the validation dipoles, with the dimensions frequency and phantom shell thickness
dependent. The COMOSAR test bench employs a 2 mm phantom shell thickness therefore the
dipoles sold for use with the COMOSAR test bench comply with the requirements set forth for a 2
mm phantom shell thickness.
MEASUREMENT UNCERTAINTY
All uncertainties listed below represent an expanded uncertainty expressed at approximately the 95%
confidence level using a coverage factor of k=2, traceable to the Internationally Accepted Guides to
Measurement Uncertainty.
