There are other special features and conditions which should be taken into account In addition to the rules for the determination of the reference point and for the selection of the appropriate line from a whole lot e the baseline and e the tolerance zone exceptions should be considered The two terms are illustrated using an example The base line is the limitation of the line to a fixed minimum value clipping It is used only with limit lines of the upper type ie maximum level in K10 K11 The effect is such that a relative line is limited to this base value at the latest even if the calculation based on the actual reference level would yield lower limit values The base line is used with PVT TRA and MOD With TRA for example the limitation is at a maximum S N ratio of 36 dBm Tolerance zones are a speciality of modulation measurement They indicate a region in which the predefined limit value is exceeded but where a certain number of overranges is tolerated The combination of base line and tolerance zone is especially interesting The following cases are possible The different limit line variations are given from left to right The texts in the different sections specify the evaluation of the signal at this point provided the measured value is in the corresponding section The displayed relative limit line cuts the tolerance zone represented as exception line and the base line with respect to the reference level 1057 3440
