Introduction
The present document defines the conformance test requirements for radio specific parameters required directly by the
radio equipment relevant standards ETSI EN 302 217-1 [8] and ETSI EN 302 217-2 [9]. Test methods, and test report
format, for these parameters are also contained herein. It may be applied also for conformance test according other
(international or national) relevant standards that might contain a number of similar requirements.
The main body of the present document contains definitions, general requirements and test procedures (see note) for
conformance test of Digital Fixed Radio Systems (DFRS).
NOTE: It is assumed that where a clarification of a test procedure is needed, this should be described on the final
page of the test report titled "Additional information supplementary to the test report".

ETSI
7 ETSI EN 301 126-1 V2.1.1 (2025-07)
1 Scope
The present document details standardized procedures for conformance test of radio interface parameters for Point to
Point (PP) equipment used for Digital Fixed Radio Systems (DFRS). Three sets of procedures (for ER, OR and CP) are
considered in the scope of the present document:
• Procedures for radio parameters relevant to Essential Requirements (ER) and Optional Requirements (OR),
relevant to article 3.2 of Directive 2014/53/EU [i.1]. Requirements for these parameters are detailed in ETSI
EN 302 217-2 [9].
• Procedures for Complementary Requirements (CP) that, even if not considered "essential" in the light of
article 3.2 of Directive 2014/53/EU [i.1], are considered important for the operations of PP equipment. These
parameters are detailed in clause 8 of ETSI EN 302 217-1 [8].
The present document is mainly intended to be applied in conjunction with the above equipment relevant standards and
will enable commonality of test results, irrespective of the body carrying out the test.
However, the present document can be used also in conjunction with other DFRS relevant standards that would refer to
the parameters and test methods hereby described.
The conformance tests described in the present document are those related to radio specific parameters required directly
by the radio equipment relevant standards at antenna ports in conducted test methods. Conformance tests to other
boundary standards (e.g. those for system input/output interfaces (i.e. set at X/X' interface, shown in figure 2, and
related baseband process) are outside the scope of the present document.
Also, tests described in the present document are not applicable to radio equipment with integral antenna of
undetachable antenna type requiring radiated test methods.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
NOTE: In the present document the "terms" defined in this clause, when used elsewhere, are given in "italic"
font.
Complementary Requirements (CR): requirements not relevant to the essential requirements
conformance test: type testing process to verify to what extent the EUT conforms to the relevant standard
Design Objectives: (DO): regulatory and market aspects taken into account for the equipment design and/or operative
performance to be guaranteed
NOTE: Information included in the technical documentation.
Essential Requirements (ER): basic set of parameters and functions which are necessary to meet any regulatory
obligations related to the relevant standard
NOTE: In the scope of the present document, ER are those covered by article 3.2 of Directive 2014/53/EU [i.1].
Requirements covered by articles 3.1 and 3.3 of that Directive 2014/53/EU [i.1] are not in the scope of the
present document.
full conformance: status of the Equipment Under Test (EUT) when it has successfully passed all the requirements of
the conformance test process and therefore meets all the requirements of the relevant standard which the EUT refers to
integral (integrated) antenna: antenna which is indicated in the technical documentation as part of the radio
equipment; it is not physically separable from the equipment
NOTE: Under this category different applications are possible, to which the following more detailed definitions
apply:
1) Detachable (integral) antenna: even when equipment with integral antenna is concerned, the
manufacturer's design might still permit, through specific procedure, to separate the antenna from
the equipment at an internal antenna port, physically suitable for testing purpose. In such cases the
assessment of the radio equipment and of the antenna against requirements of ETSI EN 302 217
parts 1 [8], 2 [9] and 4 [i.5] should be done separately with conducted test procedures.
2) Undetachable (integral) antenna: in this case the manufacturer's design does not permit the
physical access to the antenna port; nevertheless, for the equipment in the scope of ETSI
EN 302 217 parts 1 [8], 2 [9] and 4 [i.5], a "virtual" antenna port can be identified, according the
indication in the technical documentation, where all requirements can be referenced. However, in
this case only radiated test procedures (not in the scope of the present document) can be made.
ETSI
10 ETSI EN 301 126-1 V2.1.1 (2025-07)
mandatory requirements: requirement which the Equipment Under Test (EUT) has to meet
NOTE: To achieve full conformance to a relevant standard all its requirements are mandatory.
manufacturer: organization requesting the approval
Optional Requirements (OR): requirement whose feature is not mandatory (e.g. Automatic Transmit Power Control
(ATPC), etc.)
NOTE: Once such an option has been implemented it becomes formally equivalent to an essential requirement.
relevant standard: standard (international or national) that provides the limits of the requirements for the equipment
under test
technical documentation: See Articles 10 and 21 of Directive 2014/53/EU [i.1] (see note).
NOTE: It is assumed that when tests are performed based on a relevant standard not related to obligation of
article 2 of that Directive, an equivalent documentation would also be provided before the test.
type testing: testing process (see note) for verifying full conformance
NOTE 1: A type test is to be carried out successfully in order to achieve full conformance; it implies that the EUT
has met all the requirements (ER, CR and, if any, OR) of the relevant standard against which it has been
tested.
NOTE 2: Type testing is when at least a representative sample of equipment is tested. The test result is considered
to be applicable and representative for all other pieces of equipment manufactured identically.

4 Requirements related to DFRS equipment
conformance test
4.0 Test procedure summary
Table 1 summarizes the DFRS requirements in the light of their test procedures, based on the following classification:
• All technical elements (design objectives, DO) reported in the technical documentation, related to the intended
operation and the knowledge of the basic elements of the design.
• The list of functions and parameters which limits are included in ETSI EN 302 217-2 [9] (see note), relevant to
Essential Requirements (ERs) in article 3.2 of Directive 2014/53/EU Radio Equipment [i.1] or Optional
Requirement (OR), which, when optionally implemented in the design, are also considered as ER.
• The list of functions and parameters which limits may be included in ETSI EN 302 217-1 [8] (see note), as
Complementary Requirements (CRs) that, while not affecting the ER are considered important for the correct
function of the radio equipment itself.
• The test conditions (Ref or Ext) when test is required (TR). These are intended for a general, stand alone, use
of the present document; however, when used for assessment of ER and OR parameters according ETSI
EN 302 217-2 [9] (see note), the test conditions there described, if different, will prevail against those in the
present document.
NOTE: Or any other DFRS relevant standard referencing the present document for test procedures of similar
requirements.

Introduction
The present document defines the conformance test requirements for radio specific parameters required directly by the
radio equipment relevant standards ETSI EN 302 217-1 [8] and ETSI EN 302 217-2 [9]. Test methods, and test report
format, for these parameters are also contained herein. It may be applied also for conformance test according other
(international or national) relevant standards that might contain a number of similar requirements.
The main body of the present document contains definitions, general requirements and test procedures (see note) for
conformance test of Digital Fixed Radio Systems (DFRS).
NOTE: It is assumed that where a clarification of a test procedure is needed, this should be described on the final
page of the test report titled "Additional information supplementary to the test report".

ETSI
7 ETSI EN 301 126-1 V2.1.1 (2025-07)
1 Scope
The present document details standardized procedures for conformance test of radio interface parameters for Point to
Point (PP) equipment used for Digital Fixed Radio Systems (DFRS). Three sets of procedures (for ER, OR and CP) are
considered in the scope of the present document:
• Procedures for radio parameters relevant to Essential Requirements (ER) and Optional Requirements (OR),
relevant to article 3.2 of Directive 2014/53/EU [i.1]. Requirements for these parameters are detailed in ETSI
EN 302 217-2 [9].
• Procedures for Complementary Requirements (CP) that, even if not considered "essential" in the light of
article 3.2 of Directive 2014/53/EU [i.1], are considered important for the operations of PP equipment. These
parameters are detailed in clause 8 of ETSI EN 302 217-1 [8].
The present document is mainly intended to be applied in conjunction with the above equipment relevant standards and
will enable commonality of test results, irrespective of the body carrying out the test.
However, the present document can be used also in conjunction with other DFRS relevant standards that would refer to
the parameters and test methods hereby described.
The conformance tests described in the present document are those related to radio specific parameters required directly
by the radio equipment relevant standards at antenna ports in conducted test methods. Conformance tests to other
boundary standards (e.g. those for system input/output interfaces (i.e. set at X/X' interface, shown in figure 2, and
related baseband process) are outside the scope of the present document.
Also, tests described in the present document are not applicable to radio equipment with integral antenna of
undetachable antenna type requiring radiated test methods.

the conformance test process and therefore meets all the requirements of the relevant standard which the EUT refers to
integral (integrated) antenna: antenna which is indicated in the technical documentation as part of the radio
equipment; it is not physically separable from the equipment
NOTE: Under this category different applications are possible, to which the following more detailed definitions
apply:
1) Detachable (integral) antenna: even when equipment with integral antenna is concerned, the
manufacturer's design might still permit, through specific procedure, to separate the antenna from
the equipment at an internal antenna port, physically suitable for testing purpose. In such cases the
assessment of the radio equipment and of the antenna against requirements of ETSI EN 302 217
parts 1 [8], 2 [9] and 4 [i.5] should be done separately with conducted test procedures.
2) Undetachable (integral) antenna: in this case the manufacturer's design does not permit the
physical access to the antenna port; nevertheless, for the equipment in the scope of ETSI
EN 302 217 parts 1 [8], 2 [9] and 4 [i.5], a "virtual" antenna port can be identified, according the
indication in the technical documentation, where all requirements can be referenced. However, in
this case only radiated test procedures (not in the scope of the present document) can be made.
ETSI
10 ETSI EN 301 126-1 V2.1.1 (2025-07)
mandatory requirements: requirement which the Equipment Under Test (EUT) has to meet
NOTE: To achieve full conformance to a relevant standard all its requirements are mandatory.
manufacturer: organization requesting the approval
Optional Requirements (OR): requirement whose feature is not mandatory (e.g. Automatic Transmit Power Control
(ATPC), etc.)
NOTE: Once such an option has been implemented it becomes formally equivalent to an essential requirement.
relevant standard: standard (international or national) that provides the limits of the requirements for the equipment
under test
technical documentation: See Articles 10 and 21 of Directive 2014/53/EU [i.1] (see note).
NOTE: It is assumed that when tests are performed based on a relevant standard not related to obligation of
article 2 of that Directive, an equivalent documentation would also be provided before the test.
type testing: testing process (see note) for verifying full conformance
NOTE 1: A type test is to be carried out successfully in order to achieve full conformance; it implies that the EUT
has met all the requirements (ER, CR and, if any, OR) of the relevant standard against which it has been
tested.
NOTE 2: Type testing is when at least a representative sample of equipment is tested. The test result is considered
to be applicable and representative for all other pieces of equipment manufactured identically.

4 Requirements related to DFRS equipment
conformance test
4.0 Test procedure summary
Table 1 summarizes the DFRS requirements in the light of their test procedures, based on the following classification:
• All technical elements (design objectives, DO) reported in the technical documentation, related to the intended
operation and the knowledge of the basic elements of the design.
• The list of functions and parameters which limits are included in ETSI EN 302 217-2 [9] (see note), relevant to
Essential Requirements (ERs) in article 3.2 of Directive 2014/53/EU Radio Equipment [i.1] or Optional
Requirement (OR), which, when optionally implemented in the design, are also considered as ER.
• The list of functions and parameters which limits may be included in ETSI EN 302 217-1 [8] (see note), as
Complementary Requirements (CRs) that, while not affecting the ER are considered important for the correct
function of the radio equipment itself.
• The test conditions (Ref or Ext) when test is required (TR). These are intended for a general, stand alone, use
of the present document; however, when used for assessment of ER and OR parameters according ETSI
EN 302 217-2 [9] (see note), the test conditions there described, if different, will prevail against those in the
present document.
NOTE: Or any other DFRS relevant standard referencing the present document for test procedures of similar
requirements.
