Thesis (MScEng (Electrical and Electronic Engineering))--Stellenbosch University, 2008. / Conventional immunity tests are both time consuming and costly. There is
thus a reasonable interest in relatively quick, but accurate and cost
effective, in-house pre-compliance test techniques within an engineering
design-house. This thesis provides information on the equivalence between
in-house and conventional immunity test techniques.
Three techniques were evaluated, namely: 1. E-field radiation with a log
periodic antenna (conventional test technique); 2 E-field radiation with an inhouse
designed and constructed modified TEM cell (in-house test
technique); 3. Current injection using a complete off the shelf EMCO current
probe device (in-house test technique).
After the transfer data of the EMCO probe was verified, the modified TEM
cell design, construction and equivalent measurement tests were
performed. These tests revealed that within the respective bandwidth of
interest, the devices produced results that are equivalent to each other
within 0.9dB. Hence equivalence between in-house and conventional test
techniques is possible.
