11 TEST SETUP

Device characteristics are measured according to the test

setups given below.

Electrical characteristics are measured in a Helmholtz

arrangement

that

generates

almost

homogenous

magnetic field at the position of the device under test

(transponder), see Figure 29.

The sense coils detect the absorption modulation induced

by the transponder, whereas the reference coils sense the

magnetic flux generated by the field generating coils only.

The voltage difference measured between the sense coils

and reference coils is proportional to the magnetic field

absorption induced by the transponder.
