C.3 Substitution measurement

To determine the absolute measurement value a substitution measurement is performed. The following steps have to be

performed:

1) Replacing the UUT with the substitution antenna that is depicted as device 1 in figure C.1. The substitution

antenna will have vertical polarization.

2) Connect a signal generator to the substitution antenna, and adjust it to the measurement frequency.

3) If an OATS or a SAR is used, the measurement antenna shall be raised or lowered, to ensure that the

maximum signal is received.

4) Subsequently, the power of the signal generator is adjusted until the same level is obtained again at the

measurement equipment.

5) The radiated power is equal to the power supplied by the signal generator, increased the substitution antenna

gain minus the cable losses (values in dB).

6) This measurement shall be repeated with horizontal polarization.

NOTE: For test sites with a fixed setup of the measurement antenna(es) and a reproducible positioning of the

UUT, correction values from a verified site calibration can be used alternatively.

C.4 Guidance for testing technical requirements

This clause provides guidance on how the various technical requirements can be verified using radiated measurements.

C.4.1 Essential radio test suites and corresponding test sites

Table C.1 provides guidance on the test site to be used for each of the essential radio test suites when performing

radiated measurements on integral antenna equipment.
