4.1.3 Width of the transmission window
Determining the width of the transmission window
The following approximation formula can be used for practical applications:
% y/
B: Width of the transmission window
L: Length of the transmission window
Tracking tolerances
The width of the transmission window (B) is particularly important for the mechanical tracking
tolerance. The formula for the dwell time is valid without restriction when B is observed.
4.1.4 Impact of secondary fields
Secondary fields in the range from 0 to 20 mm always exist.
They should only be applied during planning in exceptional cases, however, since the
read/write distances are very limited. Exact details of the secondary field geometry cannot be
given, since these values depend heavily on the operating distance and the application.
