The input signal to the substitution antenna shall be recorded as a power level and corrected for any change of input
attenuator setting of the measuring receiver.
The measurement shall be repeated with the test antenna and the substitution antenna oriented for horizontal
polarization.

4.3 Conformance requirements for receivers parameters
4.3.1 Receiver sensitivity
4.3.1.1 Definition
The maximum usable sensitivity of the receiver is the minimum level of the signal (H-field strength) at the nominal
frequency of the receiver which, when applied to the receiver input with normal test modulation (see clause 4.2.1.3),
produces either of the following:
• a (S + N)/N ratio of 6 dB, measured at the terminals of the electroacoustic transducer for beacons with an
acoustic signal indication;
• an unambiguous optical indication of a received beacon signal for beacons with optical signal indication.
4.3.1.2 Method of measurement
For beacons with an acoustic indicator, the terminals of the transducer shall be made accessible for the purposes of the
present document.
A test signal at a carrier frequency equal to the nominal frequency of the receiver, modulated by the normal test
modulation (see clause 4.2) shall be applied in the best coupling position, i.e. when the antenna rod is parallel to the
lines of the magnetic field. An audio frequency load and a measuring instrument for measuring the S/N ratio shall be
connected to the terminals of the electroacoustic transducer.
ETSI
13 ETSI EN 300 718-1 V2.1.1 (2018-01)
The level of the test signal shall be adjusted until a (S + N)/N ratio of 6 dB is obtained. The (S + N)/N ratio is measured
flat over a bandwidth of 20 kHz. The field strength at the receiver shall be measured by a substitution method. Under
these conditions, the level of the test signal at the input is the value of the reference maximum usable sensitivity which
shall be recorded.
For beacons providing optical indication, the level of the test signal shall be adjusted until an unambiguous indication of
the presence of a transmitter is obtained. The field strength at the receiver shall be measured by a substitution method.
Under these conditions, the level of the test signal at the input is the value of the reference maximum usable sensitivity
which shall be recorded.
4.3.1.3 Limits
The appropriate indication shall be achieved for a field strength not higher than 80 nA/m at a frequency of 457 kHz.
4.3.2 Receiver spurious emissions
4.3.2.1 Definition
The level of spurious emissions shall be measured at normal conditions as their effective radiated power or field
strength radiated by the cabinet and the integral antenna.
4.3.2.2 Radiated H-field
4.3.2.2.1 Method of measurement (< 30 MHz)
The field strength shall be measured for frequencies below 30 MHz. The equipment under test shall be measured at a
distance of 10 m on an outdoor test site. The test antenna shall be a calibrated shielded magnetic field antenna. The
equipment under test and test antenna shall be arranged as stated in annex B, clause B.1.
The equipment under test shall be switched on in receive mode. The measuring receiver shall be tuned over the
frequency range 9 kHz to 30 MHz.
At each frequency at which a spurious signal is detected the equipment under test and the test antenna shall be rotated
until maximum field strength is indicated on the measuring receiver. This level shall be noted.
The limits are quoted in dBμA or dBμA/m, so it is necessary to reduce the reading as explained in annex D for
measuring equipment calibrated in dBμV or dBμV/m.
4.3.2.2.2 Limits
Radiated emissions below 30 MHz shall not exceed the generated H-field at 10 m given in table 4.

The equipment shall be switched on in receive mode, and the measuring receiver shall be tuned over the frequency
range 30 MHz to 1 000 MHz.
At each frequency at which a spurious component is detected, the test antenna shall be raised and lowered through the
specified range of heights until a maximum signal level is detected on the measuring receiver.
The equipment shall then be rotated through 360° in the horizontal plane, until the maximum signal level is detected by
the measuring receiver.
The maximum signal level detected by the measuring receiver shall be noted.
The substitution antenna shall be oriented for vertical polarization and calibrated for the frequency of the spurious
component detected.
The frequency of the calibrated signal generator shall be set to the frequency of the spurious component detected. The
input attenuator setting of the measuring receiver shall be adjusted in order to increase the sensitivity of the measuring
receiver, if necessary.
The test antenna shall be raised and lowered through the specified range of heights to ensure that the maximum signal is
received.
When a test site according to clause B.3 is used, there is no need to vary the height of the antenna.
The input signal to the substitution antenna shall be adjusted until an equal or a known related level to that detected
from the receiver is obtained on the measuring receiver.
The input signal to the substitution antenna shall be recorded as a power level and corrected for any change of input
attenuator setting of the measuring receiver.
The measurement shall be repeated with the test antenna and the substitution antenna oriented for horizontal
polarization.
The measure of the effective radiated power of the spurious components is the larger of the two power levels recorded
for each spurious component at the input to the substitution antenna, corrected for the gain of the substitution antenna if
necessary.
4.3.2.3.2 Limits
The power of any radiated emission shall not exceed the values given in table 5.
Table 5
State 30 MHz to 1 000 MHz
Operating 2 nW
4.3.3 Receiver blocking
Receiver blocking is not applicable for avalanche beacons, due to propagation physics (i.e. magnetic).
The operating range of avalanche beacons is very small, typically 60 m (the minimum range to be compliant to the
standard is about 40 m).
Avalanche beacons use magnetic antennas. They operate in the near field (the transition near field / far field is at
lambda/2pi = 104 m).
In the near field the magnetic field strength varies with 1/r3; therefore avalanche beacons receiver intrinsically need to
handle large signal strength ratios: 60 m / 1 m correspond to a dynamic range of 106 dB at least.
This is tested indirectly with clause 4.4.2 of ETSI EN 300 718-2 [4] "Changes in the received signal".

During type tests, the power source of the equipment shall be replaced by an external test power source capable of
producing normal and extreme test voltages as specified in clauses 5.3.2 and 5.4.2. The internal impedance of the
external 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 external test power source shall be measured at the input terminals of the equipment.
The non-grounded terminal of the batteries shall be disconnected, but batteries shall be left in place. The external test
power source shall be suitably de-coupled and applied as close to the equipment battery terminals as practicable. The
power leads shall be as short as practicable and properly dressed. For radiated measurements fully charged internal
batteries should be used. The batteries used should be as supplied or recommended by the manufacturer.
During tests the external test power source voltages shall be within a tolerance ±1 % relative to the voltage at the
beginning of each test.
5.3 Normal test conditions
5.3.1 Normal temperature and humidity
The normal temperature and humidity conditions for tests shall be any convenient combination of temperature and
humidity within the following ranges:
• temperature: +15°C to +35°C;
• relative humidity: 20 % to 75 %.
When it is impracticable to carry out tests under these conditions, a note to this effect, stating the ambient temperature
and relative humidity during the tests, shall be added to the test report.
5.3.2 Normal test voltage
The normal test voltage shall be declared by the manufacturer. The values shall be stated in the test report.
5.4 Extreme test conditions
5.4.1 Extreme temperatures
The extreme operating and storage temperatures used for the tests shall be those declared by the manufacturer for the
equipment.
The equipment shall be able to operate correctly in the temperature range from -20 to +45°C and shall be stored without
damage in the temperature range from -25 to +70°C.

5.4.2 Extreme test voltages
5.4.2.1 General requirement
The extreme test voltages shall be declared by the manufacturer.
5.4.2.2 Procedure for tests at extreme temperatures
Before measurements are made the equipment shall have reached thermal balance in the test chamber.
The equipment shall be switched off during the temperature stabilizing period.
In the case of equipment containing temperature stabilization circuits designed to operate continuously, the temperature
stabilization circuits shall be switched on for 15 minutes after thermal balance has been obtained, and the equipment
shall then meet the specified requirements.
If the thermal balance is not checked by measurements, a temperature stabilizing period of at least one hour, or such
period as may be decided by the accredited test laboratory, shall be allowed. The sequence of measurements shall be
chosen, and the humidity content in the test chamber shall be controlled so that excessive condensation does not occur.
5.5 Measurement uncertainty
The interpretation of the results recorded in a test report for the measurements described in the present document shall
be as follows:
• the measured value related to the corresponding limit will be used to decide whether an equipment meets the
requirements of the present document;
• the value of the measurement uncertainty for the measurement of each parameter shall be included in the test
report;
• the recorded value of the measurement uncertainty shall be, for each measurement, equal to or less than the
figures in table 6.
