Ta dokument določa merilne postopke za zahteve sprejemnika za obravnavo zahtev glede učinkovitosti spektra, določenih v členu 3.2 direktive o radijski opremi (RED) [i.7].
Koncept osnovnega sprejemnika je niz dveh parametrov, podanih v točki 5 tega dokumenta, ki zagotavlja smernice za pripravo harmoniziranega standarda (HS), ki ga lahko odgovorni tehnični odbor (TB) še dodatno izboljša.
Koncept osnovnega sprejemnika vključuje naslednja parametra:
• osnovno občutljivost sprejemnika (RBS); in
• osnovno odpornost sprejemnika (RBR).
Koncept osnovnega sprejemnika je izboljšava koncepta upravljanja motilnika signala (glej standard ETSI TS 103 361 [i.4]).

Introduction
The present document provides measurement procedures for receiver requirements to address the spectrum efficiency
requirements set out in article 3.2 of the RED [i.7].
The basis for this RX concept was developed by ETSI during two Special Task Forces.
First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential
requirements set out in article 3.2 of the RED [i.7].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
• ETSI TS 103 361 [i.4]
The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the
essential requirements set out in article 3.2 of the RED [i.7], was a continuation to implement and consider comments
received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]
There is no specification of receiver parameter values within the present document. These values will be derived from
technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies
conducted by the relevant bodies like CEPT/ECC WG SE. The limits/values for the baseline RX-conformance
requirements will be specified in the related standard.
In addition to two receiver baseline requirements, it can be necessary that the RX spurious emission requirement could
be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode or if it
is not co-located to the transmitter. The present document specifies the receiver spurious emission requirement and the
corresponding test and measurement procedure in clause 5.2.
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and related devices.
It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable
receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for
those that are disregarded.

1 Scope
The present document provides measurement procedures for receiver requirements to address the spectrum efficiency
requirements set out in article 3.2 of the RED [i.7].
The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance
for HS development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); and
• Receiver Baseline Resilience (RBR).
The Baseline receiver concept is a further development of the signal interferer handling concept, see ETSI
TS 103 361 [i.4].

3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 303 883-1 [1] and the following apply:
event failure rate: ratio of failed tests compared to total number of tests
received power at the EUT (P@EUT): received signal with a specified power level the EUT is able to detect
NOTE 1: P is similar to the specified sensitivity level for the EUT as specified in the related standard (kind of
@EUT
power (e.g. dBm or dBm/MHz) and limit, see note 2.
NOTE 2: ����������� @ ��� = � .
@���
Receiver Baseline Resilience (RBR): capability to maintain a pre-determined minimum acceptable level of
performance in the presence of unwanted signals over the frequency band of operation, applicable adjacent and remote
frequency bands
Receiver Baseline Sensitivity (RBS): capability to receive a wanted signal at application related defined input signal
levels while providing a pre-determined minimum acceptable level of technical performance
NOTE 1: The pre-determined minimum acceptable level of technical performance is the basis for all other receiver
parameters.
NOTE 2: The purpose of the sensitivity requirement is to assure a basic measure of efficient use of spectrum that
strikes balance between sensitivity and the need to avoid being sensitive to interference.
Wanted Technical Performance Criteria (WTPC): specified technical behaviour of the EUT (e.g. information via
use-interface) or specified measurable specified output signal to demonstrate that the EUT operates as intended
NOTE: The wanted technical performance will be specified in the rates standard and the requirement is closely
linked with the use-case of the EUT.

12 Draft ETSI EN 303 883-2 V2.1.0 (2024-01)
4 General
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and devices.
The baseline receiver requirements were developed based on the findings of ETSI TR 103 566 [i.2] and ETSI
TS 103 567 [i.3], where the signal interferer handling concept from ETSI TS 103 361 [i.4] has been analysed on its
applicability for the RED [i.7].
The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance
for harmonised standard development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); see clause 5.4; and
• Receiver Baseline Resilience (RBR); see clause 5.5.
The baseline receiver concept is a further development of the signal interferer handling concept, see ETSI
TS 103 361 [i.4].
In annex C these two parameters are put in relation to existing receiver parameters given in ETSI EG 203 336 [i.1] and
the assessments prepared by ETSI STF 494 and 541. Annex C additionally provides the summary
assessment/justification for this new baseline receiver concept described in the present document.
5 Receiver Requirements
5.1 General Guidance on RX measurement
Complementary information to the conformance tests in the clauses below are provided in annex A and B of ETSI
EN 303 883-1 [1], for example:
• test conditions, power supply and ambient temperatures (see clause A.5 of ETSI EN 303 883-1 [1]);
• measurement uncertainty and the interpretation of the measurement results (see clause A.8 of ETSI
EN 303 883-1 [1]);
• test setups and radiated measurements (see annex B of ETSI EN 303 883-1 [1]).
5.2 Receiver Spurious Emissions
5.2.1 Description
The RX spurious emissions shall be measured within the frequency range defined in table 2.
The receiver spurious emission requirement is applicable for communication and tracking EUT if the EUT is a receive
only device (TX not implemented) or for EUT which has a receive only mode (TX off, standby, idle).
For radiodetermination and sensor applications (e.g. radar sensor) the receiver spurious emission requirement is
applicable for EUT if it is a receive only device (receiver is separated from the transmitter within a separate housing) or
for EUT which has a receive only mode (TX off, standby, idle). The receive only mode shall be specified in the related
standard based on the intended-use and the EUT device categories. For EUT without a receive only mode than the
spurious emissions are covered by provisions of clause 5.5 of ETSI EN 303 883-1 [1] on TX unwanted emissions.
5.2.2 Limits
The limit for RX spurious emissions could be provided in the applicable related standard.
ETSI
13 Draft ETSI EN 303 883-2 V2.1.0 (2024-01)
If no limits for RX spurious emissions are provided in the related standard, then the limits in table 1 shall apply.

NOTE 1: FUPPER is the stated harmonic of fH (the upper edge of the OFR, which is measured in ETSI EN 303 883-1 [1],
clause 5.2).
NOTE 2: F has to be selected based on f and F based on f (f and f can be measured according to ETSI
LOWER L UPPER H L H
EN 303 883-1 [1], clause 5.2); for receive only devices fH and fL of the related EUT/companion device shall be
used.
NOTE 3: For EUT operating below 300 MHz the spurious emissions limits below 30 MHz shall be specified in the
related standard.
5.2.3 Conformance
5.2.3.1 General
The following conformance test shall be used for RX unwanted emissions (OOB and spurious emissions) if not
otherwise specified in the related standard.

Introduction
The present document provides measurement procedures for receiver requirements to address the spectrum efficiency
requirements set out in article 3.2 of the RED [i.7].
The basis for this RX concept was developed by ETSI during two Special Task Forces.
First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential
requirements set out in article 3.2 of the RED [i.7].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
• ETSI TS 103 361 [i.4]
The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the
essential requirements set out in article 3.2 of the RED [i.7], was a continuation to implement and consider comments
received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]
There is no specification of receiver parameter values within the present document. These values will be derived from
technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies
conducted by the relevant bodies like CEPT/ECC WG SE. The limits/values for the baseline RX-conformance
requirements will be specified in the related standard.
In addition to two receiver baseline requirements, it can be necessary that the RX spurious emission requirement could
be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode or if it
is not co-located to the transmitter. The present document specifies the receiver spurious emission requirement and the
corresponding test and measurement procedure in clause 5.2.
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and related devices.
It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable
receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for
those that are disregarded.

1 Scope
The present document provides measurement procedures for receiver requirements to address the spectrum efficiency
requirements set out in article 3.2 of the RED [i.7].
The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance
for HS development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); and
• Receiver Baseline Resilience (RBR).
The Baseline receiver concept is a further development of the signal interferer handling concept, see ETSI
TS 103 361 [i.4].

event failure rate: ratio of failed tests compared to total number of tests
interfering transmit antenna: antenna which radiates the interfering signal to EUT during the RBR test
received power at the EUT (P@EUT): received signal with a specified power level the EUT is able to detect
NOTE 1: P is similar to the specified sensitivity level for the EUT as specified in the related standard (kind of
@EUT
power (e.g. dBm or dBm/MHz) and limit, see note 2.
NOTE 2: ����������� @ ��� = � .
@���
Receiver Baseline Resilience (RBR): capability to maintain a pre-determined minimum acceptable level of
performance in the presence of unwanted signals over the frequency band of operation, applicable adjacent and remote
frequency bands
Receiver Baseline Sensitivity (RBS): capability to receive a wanted signal at application related defined input signal
levels while providing a pre-determined minimum acceptable level of technical performance
NOTE 1: The pre-determined minimum acceptable level of technical performance is the basis for all other receiver

4 General
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and devices.
The baseline receiver requirements were developed based on the findings of ETSI TR 103 566 [i.2] and ETSI
TS 103 567 [i.3], where the signal interferer handling concept from ETSI TS 103 361 [i.4] has been analysed on its
applicability for the RED [i.7].
ETSI
12 Final draft ETSI EN 303 883-2 V2.1.1 (2024-06)
The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance
for harmonised standard development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); see clause 5.4; and
• Receiver Baseline Resilience (RBR); see clause 5.5.
The baseline receiver concept is a further development of the signal interferer handling concept, see ETSI
TS 103 361 [i.4].
In annex C these two parameters are put in relation to existing receiver parameters given in ETSI EG 203 336 [i.1] and
the assessments prepared by ETSI STF 494 and 541. Annex C additionally provides the summary
assessment/justification for this new baseline receiver concept described in the present document.
5 Receiver Requirements
5.1 General Guidance on RX measurement
Complementary information to the conformance tests in the clauses below are provided in annex A and B of ETSI
EN 303 883-1 [1], for example:
• test conditions, power supply and ambient temperatures (see clause A.5 of ETSI EN 303 883-1 [1]);
• measurement uncertainty and the interpretation of the measurement results (see clause A.8 of ETSI
EN 303 883-1 [1]);
• test setups and radiated measurements (see annex B of ETSI EN 303 883-1 [1]).
5.2 Receiver Spurious Emissions
5.2.1 Description
The RX spurious emissions shall be measured within the frequency range defined in table 2.
The receiver spurious emission requirement is applicable for communication and tracking EUT if the EUT is a receive
only device (TX not implemented) or for EUT which has a receive only mode (TX off, standby, idle).
For radiodetermination and sensor applications (e.g. radar sensor) the receiver spurious emission requirement is
applicable for EUT if it is a receive only device (receiver is separated from the transmitter within a separate housing) or
for EUT which has a receive only mode (TX off, standby, idle). The receive only mode shall be specified in the related
standard based on the intended-use and the EUT device categories. For EUT without a receive only mode than the
spurious emissions are covered by provisions of clause 5.5 of ETSI EN 303 883-1 [1] on TX unwanted emissions.
5.2.2 Limits
The limit for RX spurious emissions could be provided in the applicable related standard.
If no limits for RX spurious emissions are provided in the related standard, then the limits in table 1 shall apply.
Table 1: Receiver spurious emission limits in line with ERC/REC 74-01 [i.5]

UPPER H
clause 5.2).
NOTE 2: FLOWER has to be selected based on fL and FUPPER based on fH (fL and fH can be measured according to ETSI
EN 303 883-1 [1], clause 5.2); for receive only devices f and f of the related EUT/companion device shall be
H L
used.
NOTE 3: For EUT operating below 300 MHz the spurious emissions limits below 30 MHz shall be specified in the
related standard.

Introduction
The present document provides measurement procedures for receiver requirements to address the spectrum efficiency
requirements set out in article 3.2 of the RED [i.7].
The basis for this RX concept was developed by ETSI during two Special Task Forces.
First Special Task Force: ETSI STF 494; Update of the UWB related Harmonised Standards covering the essential
requirements set out in article 3.2 of the RED [i.7].
The STF 494:
• Started: 2015-05-25
• Ended: 2016-03-31
Outcome:
• ETSI TS 103 361 [i.4]
The second Special Task Force: ETSI STF 541; Signal interferer handling, a new RX requirement to cover the
essential requirements set out in article 3.2 of the RED [i.7], was a continuation to implement and consider comments
received after the publication of the ETSI TS 103 361 [i.4].
The STF 541:
• Started: 2017-10-06
• Ended: 2019-05-31
Outcome:
• ETSI TR 103 566 [i.2]
• ETSI TS 103 567 [i.3]
There is no specification of receiver parameter values within the present document. These values will be derived from
technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies
conducted by the relevant bodies like CEPT/ECC WG SE. The limits/values for the baseline RX-conformance
requirements will be specified in the related standard.
In addition to two receiver baseline requirements, it can be necessary that the RX spurious emission requirement could
be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode or if it
is not co-located to the transmitter. The present document specifies the receiver spurious emission requirement and the
corresponding test and measurement procedure in clause 5.2.
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and related devices.
It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable
receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for
those that are disregarded.

4 General
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and devices.
The baseline receiver requirements were developed based on the findings of ETSI TR 103 566 [i.2] and ETSI
TS 103 567 [i.3], where the signal interferer handling concept from ETSI TS 103 361 [i.4] has been analysed on its
applicability for the RED [i.7].
ETSI
12 ETSI EN 303 883-2 V2.1.1 (2024-08)
The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance
for harmonised standard development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); see clause 5.4; and
• Receiver Baseline Resilience (RBR); see clause 5.5.
The baseline receiver concept is a further development of the signal interferer handling concept, see ETSI
TS 103 361 [i.4].
In annex C these two parameters are put in relation to existing receiver parameters given in ETSI EG 203 336 [i.1] and
the assessments prepared by ETSI STF 494 and 541. Annex C additionally provides the summary
assessment/justification for this new baseline receiver concept described in the present document.
5 Receiver Requirements
5.1 General Guidance on RX measurement
Complementary information to the conformance tests in the clauses below are provided in annex A and B of ETSI
EN 303 883-1 [1], for example:
• test conditions, power supply and ambient temperatures (see clause A.5 of ETSI EN 303 883-1 [1]);
• measurement uncertainty and the interpretation of the measurement results (see clause A.8 of ETSI
EN 303 883-1 [1]);
• test setups and radiated measurements (see annex B of ETSI EN 303 883-1 [1]).
5.2 Receiver Spurious Emissions
5.2.1 Description
The RX spurious emissions shall be measured within the frequency range defined in table 2.
The receiver spurious emission requirement is applicable for communication and tracking EUT if the EUT is a receive
only device (TX not implemented) or for EUT which has a receive only mode (TX off, standby, idle).
For radiodetermination and sensor applications (e.g. radar sensor) the receiver spurious emission requirement is
applicable for EUT if it is a receive only device (receiver is separated from the transmitter within a separate housing) or
for EUT which has a receive only mode (TX off, standby, idle). The receive only mode shall be specified in the related
standard based on the intended-use and the EUT device categories. For EUT without a receive only mode than the
spurious emissions are covered by provisions of clause 5.5 of ETSI EN 303 883-1 [1] on TX unwanted emissions.
5.2.2 Limits
The limit for RX spurious emissions could be provided in the applicable related standard.
If no limits for RX spurious emissions are provided in the related standard, then the limits in table 1 shall apply.
Table 1: Receiver spurious emission limits in line with ERC/REC 74-01 [i.5]
Frequency range Limit values

NOTE 1: F is the stated harmonic of f (the upper edge of the OFR, which is measured in ETSI EN 303 883-1 [1],
UPPER H
clause 5.2).
NOTE 2: FLOWER has to be selected based on fL and FUPPER based on fH (fL and fH can be measured according to ETSI
EN 303 883-1 [1], clause 5.2); for receive only devices f and f of the related EUT/companion device shall be
H L
used.
NOTE 3: For EUT operating below 300 MHz the spurious emissions limits below 30 MHz shall be specified in the
related standard.
5.2.3 Conformance
5.2.3.1 General
The following conformance test shall be used for RX unwanted emissions (OOB and spurious emissions) if not
otherwise specified in the related standard.
In case of integral antenna equipment with no antenna connector the measurement shall be radiated, otherwise
equipment with antenna connectors, the measurement shall be at the antenna port (conducted). Therefore, the related
standard need to specify the test setup (see for guidance ETSI EN 303 883-1 [1], clause B.1 for radiated or anne

There is no specification of receiver parameter values within the present document. These values will be derived from
technical specification defined by the responsible ETSI Technical Committees and/or the findings of regulatory studies
conducted by the relevant bodies like CEPT/ECC WG SE. The limits/values for the baseline RX-conformance
requirements will be specified in the related standard.
In addition to two receiver baseline requirements, it can be necessary that the RX spurious emission requirement could
be a further RX requirement in the related standard. This could be necessary if the EUT has a receive only mode or if it
is not co-located to the transmitter. The present document specifies the receiver spurious emission requirement and the
corresponding test and measurement procedure in clause 5.2.
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and related devices.
It is recommended that, in drafting the related standards, a thorough analysis is conducted on all possible applicable
receiver parameters (see annex C), selecting the most appropriate RX-requirements and having a robust reasoning for
those that are disregarded.

4 General
The present document provides practical information and guidance for the compliance receiver tests of UWB and Short
Range technology and devices.
The baseline receiver requirements were developed based on the findings of ETSI TR 103 566 [i.2] and ETSI
TS 103 567 [i.3], where the signal interferer handling concept from ETSI TS 103 361 [i.4] has been analysed on its
applicability for the RED [i.7].
ETSI
12 ETSI EN 303 883-2 V2.1.1 (2024-08)
The baseline receiver concept is a set of two parameters given in clause 5 of the present document providing guidance
for harmonised standard development, which can be further refined by the responsible TB.
Baseline receiver concept comprises the following parameters:
• Receiver Baseline Sensitivity (RBS); see clause 5.4; and
• Receiver Baseline Resilience (RBR); see clause 5.5.
The baseline receiver concept is a further development of the signal interferer handling concept, see ETSI
TS 103 361 [i.4].
In annex C these two parameters are put in relation to existing receiver parameters given in ETSI EG 203 336 [i.1] and
the assessments prepared by ETSI STF 494 and 541. Annex C additionally provides the summary
assessment/justification for this new baseline receiver concept described in the present document.
5 Receiver Requirements
5.1 General Guidance on RX measurement
Complementary information to the conformance tests in the clauses below are provided in annex A and B of ETSI
EN 303 883-1 [1], for example:
• test conditions, power supply and ambient temperatures (see clause A.5 of ETSI EN 303 883-1 [1]);
• measurement uncertainty and the interpretation of the measurement results (see clause A.8 of ETSI
EN 303 883-1 [1]);
• test setups and radiated measurements (see annex B of ETSI EN 303 883-1 [1]).
5.2 Receiver Spurious Emissions
5.2.1 Description
The RX spurious emissions shall be measured within the frequency range defined in table 2.
The receiver spurious emission requirement is applicable for communication and tracking EUT if the EUT is a receive
only device (TX not implemented) or for EUT which has a receive only mode (TX off, standby, idle).
For radiodetermination and sensor applications (e.g. radar sensor) the receiver spurious emission requirement is
applicable for EUT if it is a receive only device (receiver is separated from the transmitter within a separate housing) or
for EUT which has a receive only mode (TX off, standby, idle). The receive only mode shall be specified in the related
standard based on the intended-use and the EUT device categories. For EUT without a receive only mode than the
spurious emissions are covered by provisions of clause 5.5 of ETSI EN 303 883-1 [1] on TX unwanted emissions.
5.2.2 Limits
The limit for RX spurious emissions could be provided in the applicable related standard.
If no limits for RX spurious emissions are provided in the related standard, then the limits in table 1 shall apply.
