Longitudinal conversion loss (LCL)/NEXT
Before measuring, make sure that the voltage thresholds given in the table below are not
exceeded during the measurement. When measuring LCL or NEXT using the ARGUS,
any type of additional measurement lead can falsify the measurement. Both the length
and the position of the measurement leads with respect to each other can influence the
measurement result significantly.
