3.1.5 Electromagnetic Compatibility (EMC) - EN 301 489

The following criteria applies for the test per the standard for EMC emissions and immunity.

Table 3-8 EMC Emissions and Immunity Performance Criteria
CriterionDuring TestAfter Test
AOperate as intended. No loss of function. No unintentional responsesOperate as intended. No loss of function. No degradation of performance. No loss of stored data or user programmable functions.
BCan show loss of function. No unintentional responsesOperate as intended. Lost functions shall be self-recoverable. No degradation of performance. No loss of stored data or user programmable functions.

The following clauses under EN 301 489-1 are applicable to the TI IWR6843 and MMWAVEICBOOST Evaluation Board combo. Since the equipment requires DC power and is not a telecommunication equipment, some of the tests do not apply. Users must determine which test is applicable to their end equipment.

In addition to EN 301 489-1, there are standards which apply EN 301 489-1 to specific end equipments. They are explanatory and provide more granular detail on how to apply the standards contained within EN 301 489-1. For most 60GHz radars, EN 301 489-3 will be used. It provides clarifications for how EN 301 489-1 should be interpreted. Four key provisions apply here.

The first is that the device must be tested with transmit signals representative of actual use and receive signals for radiated immunity must be 30dB higher than the minimum usable signal. Provisions are made for the case where the defined signal causes saturation of the receiver.

The second, is the recognition of different modes of operation, such as "power off", "standby", and so forth. These modes are typically determined through a reading of the theory of operation. The device should not have an unplanned transmission during its non transmit mode.

The third, is the introduction of clarity of when radiated and conducted emissions at specific ports are applicable. This is covered in Table 4 of EN 301 489-3. From Table 4, radiated emissions are generally applicable to all equipment, DC power input/output port conducted emissions are required for all non-portable use equipment and finally AC mains input/output and wired network conduced emissions only applies to fixed location equipment.

Ultimately EN 301 489-3 shouldn't add any additional testing; rather EN 301 489-3 simply makes clear the requirements of EN 301 489-1 as applied to radars and other specific SRD niches.
