3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
integral antenna: antenna, with or without a connector, designed as, and declared as by the manufacturer, an
indispensable part of the equipment
artificial antenna: tuned reduced-radiating dummy load equal to the nominal impedance specified by the applicant
radiated measurements: measurements that involve the absolute measurement of a radiated electromagnetic field
channel bandwidth: frequency band of defined width including safety margin for operation on adjacent channels,
located symmetrically around the carrier frequency
port: any connection point on or within the Equipment Under Test (EUT) intended for the connection of cables to or
from that equipment
necessary bandwidth: is, for a given class of emission, the width of the frequency band which is just sufficient to
ensure the transmission of information at the rate and with the quality required under specified conditions. However, the
necessary bandwidths of most digital modulation formats are presently not referred to ITU-R Recommendations of
SM series
spurious emission limits: apply at frequencies above and below the fundamental transmitting frequency but separated
from the centre frequency of the emission by 250 % of the necessary bandwidth. However, this frequency separation
may be dependent on the type of modulation used, the maximum bit rate in the case of digital modulation, the type of
transmitter, and frequency coordination factors. For example, where practical the ± 250 % of the relevant Channel
Separation (CS) may be used

4 Functional characteristics
4.1 Cordless wideband audio
Cordless wideband audio equipment encompasses radio linked headphones and loudspeakers. The transmitters may be
installed in a building, fitted in a vehicle or body worn. The term cordless is also used to describe infra red and other
non-RF "wireless" links, but in the context of the present document it is restricted to RF operating systems only. Stereo
equipment can be designed for required channel bandwidths of 200 kHz or less but only with a high cost penalty,
however consumer wideband (multichannel) audio equipment and stereo equipment using e.g. Zenith-GE pilot tone
systems or digital modulation need to declare wider bandwidths as defined in the present document.
Other equipment that may be connected to cordless audio equipment shall fulfil the standards applicable to that
equipment (if any).
ETSI
11 ETSI EN 301 357-1 V1.1.2 (2000-08)

figures in the table of measurement uncertainty as in clause 10.
6 Test conditions, power sources and ambient
conditions
6.1 Normal and extreme test-conditions
Type tests shall be made under normal test conditions, and also, where stated, under extreme test conditions.
The test conditions and procedures shall be as specified in subclauses 6.2 to 6.4.2.4.
6.2 Test power source
During type tests the power source of the equipment shall be replaced by a test power source, capable of producing
normal and extreme test voltages as specified in subclauses 6.3.2 and 6.4.2. The internal impedance of the test power
source shall be low enough for its effect on the test results to be negligible. For the purpose of the tests, the voltage of
the power source shall be measured at the input terminals of the equipment.
For battery-operated equipment, the battery shall be removed and the test power source shall be suitably decoupled and
applied as close to the equipment battery term
