The manufacturer shall declare which alternative shall be used Alternative A: composite equipment A combination of the radio equipment part and a specific type of host equipment may be used for assessment according to the present document. Where a specific combination of host equipment and a radio equipment part is tested as a composite system for compliance, repeat testing shall not be required for: - those other combinations of hosts and radio equipment parts which are based on substantially similar host models in the circumstance that the variations in mechanical and electrical properties between such host models are unlikely to significantly influence the intrinsic immunity and unwanted emissions of the radio equipment part; - the radio equipment part which cannot be used without mechanical, electrical, or software modification in variations of host equipment different from those represented by the units for which compliance to the present document has been demonstrated. For all other combinations, each combination shall be tested separately.
9 9 EN V1.2.1 ( ) Alternative B: use of a test jig or host Where the radio equipment part is intended for use with a variety of host systems, the manufacturer shall supply a suitable test configuration consisting of either a host system intended for normal use or a test jig that is representative of the range of host systems in which the device may be used. The test jig shall allow the radio equipment part to be powered and stimulated in a way similar to the way it would be powered and stimulated when connected to or inserted into host equipment. 5.3 Assessment procedures The performance assessment shall be based upon: - maintenance of function(s); - the way the eventual loss of function(s) can be recovered; - unintentional behaviour of the EUT. The test system shall set up a communications link in the same manner as the Equipment Under Test's (EUT) normal intended use. Any user defined data fields in the memory or storage of the EUT shall be filled in a way representative of normal intended use. The assessment procedure shall verify that the communications link is maintained and that there is no loss of user control functions as declared by the manufacturer or loss of the stored user defined data. 5.4 Ancillary equipment The provision of EN [1], clause 5.4 shall not apply as ancillary equipment is outside the scope of the present document. 5.5 Equipment classification Hand portable equipment, or combinations of equipment, declared as capable of being powered for intended use by the main battery of a vehicle shall additionally be considered as vehicular mobile equipment. Hand portable or mobile equipment, or combinations of equipment, declared as capable of being powered for intended use by ac mains shall additionally be considered as fixed station equipment. 6 Performance criteria 6.1 General performance criteria The performance criteria are: - performance criteria A for immunity tests with phenomena of a continuous nature; - performance criteria B for immunity tests with phenomena of a transient nature; - performance criteria C for immunity tests with power interruptions exceeding a certain time. The equipment shall meet the minimum performance criteria as specified in the following clauses.
10 10 EN V1.2.1 ( ) 6.2 Performance table Table 1: Performance criteria Criteria During test After test A Shall operate as intended May show degradation of performance (see note 1) Shall be no loss of function Shall be no unintentional transmissions Shall operate as intended Shall be no degradation of performance (see note 2) Shall be no loss of function Shall be no loss of stored data or user programmable functions B May show loss of function (one or more) May show degradation of performance (see note 1) No unintentional transmissions Functions shall be self-recoverable Shall operate as intended after recovering Shall be no degradation of performance (see note 2) Shall be no loss of stored data or user programmable functions C May be loss of function (one or more) Functions shall be recoverable by the operator Shall operate as intended after recovering Shall be no degradation of performance (see note 2) NOTE 1: Degradation of performance during the test is understood as a degradation to a level not below a minimum performance level specified by the manufacturer for the use of the apparatus as intended. In some cases the specified minimum performance level may be replaced by a permissible degradation of performance. If the minimum performance level or the permissible performance degradation is not specified by the manufacturer then either of these may be derived from the product description and documentation (including leaflets and advertising) and what the user may reasonably expect from the apparatus if used as intended. NOTE 2: No degradation of performance after the test is understood as no degradation below a minimum performance level specified by the manufacturer for the use of the apparatus as intended. In some cases the specified minimum performance level may be replaced by a permissible degradation of performance. After the test no change of actual operating data or user retrievable data is allowed. If the minimum performance level or the permissible performance degradation is not specified by the manufacturer then either of these may be derived from the product description and documentation (including leaflets and advertising) and what the user may reasonably expect from the apparatus if used as intended. 6.3 Performance criteria for Continuous phenomena applied to Transmitters (CT) The performance criteria A shall apply. Tests shall be repeated with the EUT in standby mode (if applicable) to ensure that unintentional transmission does not occur. In systems using acknowledgement signals, it is recognized that an ACKnowledgement (ACK) or Not ACKnowledgement (NACK) transmission may occur, and steps should be taken to ensure that any transmission resulting from the application of the test is correctly interpreted. 6.4 Performance criteria for Transient phenomena applied to Transmitters (TT) The performance criteria B shall apply, except for voltage dips of 100 ms and voltage interruptions of ms duration, for which performance criteria C shall apply. Tests shall be repeated with the EUT in standby mode (if applicable) to ensure that unintentional transmission does not occur. In systems using acknowledgement signals, it is recognized that an acknowledgement (ACK) or notacknowledgement (NACK) transmission may occur, and steps should be taken to ensure that any transmission resulting from the application of the test is correctly interpreted.
11 11 EN V1.2.1 ( ) 6.5 Performance criteria for Continuous phenomena applied to Receivers (CR) The performance criteria A shall apply. Where the EUT is a transceiver, under no circumstances, shall the transmitter operate unintentionally during the test. In systems using acknowledgement signals, it is recognized that an ACK or NACK transmission may occur, and steps should be taken to ensure that any transmission resulting from the application of the test is correctly interpreted. 6.6 Performance criteria for Transient phenomena applied to Receivers (TR) The performance criteria B shall apply, except for voltage dips of 100 ms and voltage interruptions of ms duration for which performance criteria C shall apply. Where the EUT is a transceiver, under no circumstances, shall the transmitter operate unintentionally during the test. In systems using acknowledgement signals, it is recognized that an ACK or NACK transmission may occur, and steps should be taken to ensure that any transmission resulting from the application of the test is correctly interpreted. 7 Applicability overview 7.1 Emission General EN [1], table 2 contains the applicability of EMC emission measurements to the relevant ports of radio equipment Special conditions No special conditions shall apply to radio equipment in the scope of the present document. 7.2 Immunity General EN [1], table 2, contains the applicability of EMC immunity measurements to the relevant ports of radio equipment Special conditions No special conditions are relevant for products covered in the present document.
