Methods Applied
and
Interpretation
of
Parameters:
• Measurement Conditions: Further details are available from the Validation Report at the end
of
the certificate. All figures stated in the certificate are valid at the frequency indicated.
• Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed
point exactly below the center marking
of
the flat phantom section, with the arms oriented
parallel to the body axis.
• Feed Point Impedance
and
Return Loss: These parameters are measured with the dipole
positioned under the liquid filled phantom. The impedance stated is transformed from the
measurement at the SMA connector to the feed point. The Return Loss ensures low
reflected power. No uncertainty required.
• Electrical Delay: One-way delay between the SMA connector and the antenna feed point.
No uncertainty required.
• SAR measured: SAR measured at the stated antenna input power.
• SAR normalized: SAR as measured, normalized to an input power
of
1
Wat
the antenna
connector.
• SAR
for
nominal TSL parameters: The measured TSL parameters are used to calculate the
nominal SAR result.
The reported uncertainty
of
measurement is stated as the standard uncertainty
of
Measurement multiplied by the coverage factor k=2, which for a normal distribution
Corresponds to a coverage probability
of
approximately 95%.
