The power reading on the spectrum analyser can be directly related to the peak power limit when a spectrum analyser
resolution bandwidth of 50 MHz is used for the measurements. If a spectrum analyser resolution bandwidth of X MHz
is used instead, the maximum peak power limit shall be scaled down by a factor of 20 log (50/X), where X represents
the measurement bandwidth used.
EXAMPLE: If the maximum peak power in a particular frequency band is 0 dBm/50 MHz, and a 3 MHz
resolution bandwidth is used in case of an impulsive technology, then the measured value shall not
exceed -24,4 dBm (see [1], clause A.3).
For rf carrier based modulation using multi-tone carriers and not having gating techniques implemented, the maximum
peak power limit shall be scaled down by a different factor of 10 log(50/X), where X represents the measurement
bandwidth used.

Table 2 is based upon CEPT Report 45 [i.13]. The Commission Decision 2007/131/EC on UWB [i.4] is currently under
revision. The amended EC/DEC is expected within 2014.
The power reading on the spectrum analyser can be directly related to the peak power limit when a spectrum analyser
resolution bandwidth of 50 MHz is used for the measurements. If a spectrum analyser resolution bandwidth of X MHz
is used instead, the maximum peak power limit shall be scaled down by a factor of 20 log (50/X), where X represents
the measurement bandwidth used.
EXAMPLE: If the maximum peak power in a particular frequency band is 0 dBm/50 MHz, and a 3 MHz
resolution bandwidth is used in case of an impulsive technology, then the measured value shall not
exceed -24,4 dBm (see TS 102 883 [1], clause A.3).
For rf carrier based modulation using multi-tone carriers and not having gating techniques implemented, the maximum
peak power limit shall be scaled down by a different factor of 10 log(50/X), where X represents the measurement
bandwidth used.
4.3.4 Measurement uncertainty
The interpretation of the results for the measurements uncertainty shall be as given in TS 102 883 [1], clause 5.7,

receiver spurious emission testing applies only when the equipment can work in a receive-only mode.
4.4.2 Test procedure
The radiated test procedures as defined in clause 7.7 shall be used.
4.4.3 Limit
The narrowband spurious emissions of the receiver shall not exceed the values in Table 3 in the indicated bands (see
CEPT/ERC/REC 74-01 [i.7]).

Frequency range Limit
30 MHz to 1 GHz -57 dBm (e.r.p.)

The exterior limit is defined, for each UWB device installed in a road or rail vehicle, as the maximum mean e.i.r.p.

The reference plane for the 0 degree is the sensor mounting height. Figure 1 shows the principle of these regulations.

every local maximum should be below the limits.

Table 2 is based upon CEPT Report 45 [i.13]. The Commission Decision 2007/131/EC on UWB [i.4] is currently under
revision. The amended EC/DEC is expected within 2014.
The power reading on the spectrum analyser can be directly related to the peak power limit when a spectrum analyser
resolution bandwidth of 50 MHz is used for the measurements. If a spectrum analyser resolution bandwidth of X MHz
is used instead, the maximum peak power limit shall be scaled down by a factor of 20 log (50/X), where X represents
the measurement bandwidth used.
EXAMPLE: If the maximum peak power in a particular frequency band is 0 dBm/50 MHz, and a 3 MHz
resolution bandwidth is used in case of an impulsive technology, then the measured value shall not
exceed -24,4 dBm (see TS 102 883 [1], clause A.3).
For rf carrier based modulation using multi-tone carriers and not having gating techniques implemented, the maximum
peak power limit shall be scaled down by a different factor of 10 log(50/X), where X represents the measurement
bandwidth used.

4.4.2 Test procedure
The radiated test procedures as defined in clause 7.7 shall be used.

4.5 Exterior Limit
4.5.1 Definition
The exterior limit is defined, for each UWB device installed in a road or rail vehicle, as the maximum mean e.i.r.p.
spectral density for the emissions outside the vehicle at elevation angles higher than 0 degree (CEPT Report 45 [i.13]).
The reference plane for the 0 degree is the sensor mounting height. Figure 1 shows the principle of these regulations.

every local maximum should be below the limits.
