6.2 Host s stems a d mo ular EUT

This s bclau e des rib s how to config re EUTs that are a host s stem or mod lar in nature

Mod lar s stems can comprise dif erent typ s of mod le(s), for example the EUT can b :

• an external mod le, for example an infra-red remote control;

• an internal mod le, for example a computer hard dis ;

Trang 21

• a mou ted mod le, for example a sou d card or a vide card.

Mod les inten ed to b marketed an /or sold se arately from a host s al b as es ed with at

le st one re resentative host s stem The mod les may b internal, mou ted, plu -in or

external as i u trated in Fig re 2 The p rt s) of an mod le b in as es ed s al b

Mod les whose fu ctional ty an con ectivity al ow them to b either, plu -in, internal,

where it can b s own that one p rtic lar config ration provides a worst case, me s rement

in the worst case config ration is s ficient to s ow compl an e

When the EUT is a host, it s al b config red with mod les so that the res ltin s stem is

re resentative of typical u e

In the case where the EUT is a mod le, the host is con idered as an AE

In the case of plu -in, mou ted, external or internal mod les, the host s al b located in the

Trang 22

In ad ition, d rin pres an me s rements, the ar an ement of the EUT, the ar an ement of

the local AE an the placement of ca les s al b varied within the ran e of typical an

normal placement to at empt to determine the ca le ar an ement givin the maximum

emis ion level, as des rib d in An ex D

The ar an ement for formal me s rement s al b re resentative of a typical ar an ement of

the EUT, local AE an as ociated ca l n

eq ipment, ta le- o eq ipment or combination there f as defined in D.1.1 an i u trated in

Fig re D.2 to Fig re D.12

For some prod cts it is not alway o viou how the EUT an /or AE s ould b ar an ed This

may b d e to variation in the config ration of the EUT in practice, ph sical or practical

l mitation Examples of these ar an ements in lu e:

• wal , cei n or rac mou ted,

• han held,

• b dy worn

For example, a vide projector can b p sitioned in variou way with resp ct to wal s, cei n
