4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be in accordance with its intended use but, as a minimum, shall be that specified in the test
conditions contained in the present document. The equipment shall comply with all the technical requirements of the
present document at all times when operating within the boundary limits of the operational environmental profile
defined by its intended use.
4.2 Conformance requirements
4.2.1 Equipment with and without integral antenna
For the purposes of conducted measurements on an EUT a 50 Ω RF connection point shall be provided for test
purposes.
For EUT with integral antenna the connection point shall correspond to the input of the integral antenna. The
connection point may be a modification made for the purposes of testing and need not be a permanent part of the EUT
when made available for sale.
The unit provided to the test lab may be fitted with a temporary antenna connector with the integral antenna
disconnected.
4.2.2 Transmitter operating frequency and frequency error
4.2.2.1 Definition
The operating frequency is the nominal value of the carrier frequency.
The frequency error is the difference between the actual carrier frequency and its nominal value of 1 090 MHz.
4.2.2.2 Limits
The nominal value of carrier frequency of the transmissions shall be 1 090 MHz.
The absolute value of the frequency error shall not exceed 100 kHz.
4.2.2.3 Conformance
The conformance tests for this requirement shall be as defined in clause 5.3.1.
ETSI
11 ETSI EN 303 213-5-2 V1.1.1 (2022-04)
4.2.3 Spectrum mask
4.2.3.1 Definition
A spectrum mask is a set of limit lines applied to a plot of a transmitter spectrum. The purpose is to constrain emissions
at frequencies in the Out of Band domain which lies immediately outside the intended Operating Channel.
For the purposes of the present document, the Out of Band domain extends to ±78 MHz from the measured operating
frequency (i.e. 1 090 MHz ± frequency error). The frequencies outside the Out of Band domain are defined as the
spurious domain.
The definition of the spectrum mask is chosen as an alternative method to the specification of Out of Band domain
emissions.
4.2.3.2 Limits
The measured spectrum shall be below the limit lines shown in Figure 1.

12 ETSI EN 303 213-5-2 V1.1.1 (2022-04)
NOTE 1: The spectrum mask is consistent with the mask specified in ICAO Annex 10 Volume IV Figure 3.5 [4].
NOTE 2: Figure 1 shows the spectrum centred on the carrier frequency and will therefore shift in its entirety up to
the tolerance specified in clause 4.2.2.2.
4.2.3.3 Conformance
The conformance tests shall be as defined in clause 5.3.3.
4.2.4 Residual Power Output
4.2.4.1 Definition
The residual power output is the power output when not in the active state.
4.2.4.2 Limits
The residual power output shall not exceed the limits shown in Table 1.
Table 1: Residual Power Output Limits
Frequency Range Limit
9 kHz ≤ f ≤ 1 000 MHz -57 dBm
1 000 MHz < f ≤ 1 087 MHz -47 dBm
1 087 MHz < f ≤ 1 093 MHz -70 dBm
1 093 MHz < f ≤ 6 000 MHz -47 dBm
NOTE: These limits are specified in ERC Recommendation 74-01 [i.4], Table 2, and EUROCAE ED-102B [i.5],
clause 2.2.2.2.11.
4.2.4.3 Conformance
The conformance tests for this requirement shall be as defined in clause 5.3.4.
4.2.5 Spurious emissions of transmitter in active mode
4.2.5.1 Definition
Spurious emissions are unwanted emissions in the spurious domain. For active transmitters, the spurious domain is all
frequencies apart from the operating channel and the Out of Band domain.
4.2.5.2 Limits
The power of any unwanted emission in the spurious domain shall not exceed -13 dBm or 60 dB below PEP (whichever
is less stringent).
NOTE: These limits are specified in Appendix 3, Table I of ITU Radio Regulations [i.7] for the
Radiodetermination service category.
4.2.5.3 Conformance
The conformance tests for this requirement shall be as defined in clause 5.3.5.
ETSI
13 ETSI EN 303 213-5-2 V1.1.1 (2022-04)
4.2.6 Transmitter Intermodulation attenuation
4.2.6.1 Definition
The transmit intermodulation level is the power of the intermodulation products when an external signal is injected into
the antenna connector at a mean power level of 30 dB lower than that of the mean power of the wanted signal.
It is specified as the ratio, in dB, of the PEP level to the power level of the third order intermodulation product.
4.2.6.2 Limits
The intermodulation attenuation ratio shall be at least 40 dB in the presence of the defined external signal within a
frequency range from 962 MHz to 1 215 MHz.
4.2.6.3 Conformance
The conformance tests for this requirement shall be as defined in clause 5.3.6.
4.2.7 Duty Cycle
4.2.7.1 Definition
The duty cycle is the ratio expressed as a percentage, of the cumulative duration of transmissions within an observation
interval and the interval itself, as measured in an observation bandwidth. The duty cycle is calculated based on the half
power point of the individual pulses within a message with the maximum number of allowable pulses. This threshold
takes into account maximum allowable pulse widths and expected random variation in transmission timing.
The duty cycle is controlled to limit the impact of each transmitter in a multi transmitter environment.
4.2.7.2 Limits
The duty cycle of the transmitter shall not exceed 0,05 %.
NOTE: This limit is consistent with the maximum average squitter rates as specified in ICAO Annex 10,
clause 3.1.2.8 [4], EUROCAE ED-102B [i.5], clause 2.2.3.3.2.10, ICAO Doc-9871 [i.6], Table C-35. The
squitter rate for transmitters used for this purpose is 6.2 messages per second. Squitters are scheduled
with some randomness so any individual second may vary. The squitter rate of the transmitter could be up
to 11 messages per second.
4.2.7.3 Conformance
The conformance tests for this requirement shall be as defined in clause 5.3.7.
4.2.8 Peak Output Power
4.2.8.1 Definition
The peak output power is the power level measured at the highest point in the time domain of the power envelope of the
transmitted message.
4.2.8.2 Limits
For a reference transmitter, the peak output power shall not exceed 57 dBm (500 W).
NOTE: This limit is consistent with ICAO Annex 10, Volume IV [4], clause 3.1.1.7.11.1 and Table 5-2.
For a ground vehicle tracking transmitter, the peak output power shall not exceed 50 dBm (100 W).
ETSI
14 ETSI EN 303 213-5-2 V1.1.1 (2022-04)
