Annex C (normative):

Measurement procedures for radiated measurement

This annex gives the general procedures for radiated measurements using the test sites and arrangements described in

annex B.

Preferably, radiated measurements shall be performed in a FAR, see clause C.2. Radiated measurements in an OATS or

SAR are described in clause C.1.

C.1 Radiated measurements in an OATS or SAR

Radiated measurements shall be performed with the aid of a measurement antenna and a substitution antenna, in test

sites described in annex B. The measurement set-up shall be calibrated according to the procedure defined in this annex.

The UUT and the measurement antenna shall be oriented such as to obtain the maximum emitted power level. This

position shall be recorded in the measurement report.

a) The measurement antenna (device 2 in figure C.1) shall be oriented initially for vertical polarization unless

otherwise stated and the UUT (device 1 in figure C.1) shall be placed on the support in its standard position

and switched on.

b) The measurement equipment (device 3 in figure C.1) shall be connected to the measurement antenna and

set-up according to the specifications of the test.

c) The UUT shall be rotated through 360° in a horizontal plane until a higher maximum signal is received.

d) The measurement antenna shall be raised or lowered again through the specified height range until a maximum

is obtained. This level shall be recorded.

e) This measurement shall be repeated for horizontal polarization.

NOTE: This maximum may be a lower value than the value obtainable at heights outside the specified limits.

C.2 Radiated measurements in a FAR

For radiated measurements using a FAR, the procedure is identical to the one described in clause C.1, except that the

height scan is omitted.
