6.11.2.1 Basics on Limit Lines
Limit lines are used to define amplitude curves or spectral distribution boundaries in
the result diagram which are not to be exceeded. They indicate, for example, the upper
limits for interference radiation or spurious waves which are allowed from a device
under test (DUT). When transmitting information in TDMA systems (e.g. GSM), the
amplitude of the bursts in a time slot must adhere to a curve that falls within a specified
