Final draft ETSI EN 300 328 V1.8.1 (2012-04) B.3 Test fixture B.3.1 Conducted measurements and use of test fixture In view of the low power levels of the equipment to be tested under the present document, conducted measurements may be applied to equipment provided with a (temporary) antenna connector, e.g. by means of a spectrum analyser.
B.4.1 Final draft ETSI EN 300 328 V1.8.1 (2012-04) Power supplies for the battery powered UUT All tests should be performed using power supplies wherever possible, including tests on UUT designed for batteryonly use. For battery powered equipment, power leads should be connected to the UUT's supply terminals (and monitored with a digital voltmeter) but the battery should remain present, electrically isolated from the rest of the equipment, possibly by putting tape over its contacts.
Final draft ETSI EN 300 328 V1.8.1 (2012-04) 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.
C.3 Final draft ETSI EN 300 328 V1.8.1 (2012-04) 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.
C.4.2 Final draft ETSI EN 300 328 V1.8.1 (2012-04) Guidance for testing Adaptivity (Channel Access Mechanism) This clause provides guidance on how the Adaptivity (see clauses 4.3.1.6 or 4.3.2.5) and the Receiver Blocking (clauses 4.3.1.1 or 4.3.2.10) requirements can be verified on integral antenna equipment using radiated measurements. C.4.2.1 Measurement Set-up Figure C.2 describes an example of a set-up that can be used to perform radiated adaptivity and receiver blocking tests. Figure C.
Final draft ETSI EN 300 328 V1.8.1 (2012-04) C.4.2.3 Test method The test procedure shall be as follows: • Replace the substitution antenna with the UUT once the calibration is performed. • The UUT shall be positioned for maximum e.i.r.p. towards the horn antenna. NOTE: This position was recorded as part of the procedure in clause 5.3.2.2.2 (second paragraph). The test method is further as described under clause 5.3.7.2.1.
