dB Voltage level Voltage level measurement is used in order to
ascertain overall attenuation or boosting of a
transmission system.

dbrEF Reference level Reference value for alternating voltage level measurement (see dB).
dEMAnd tiME Time interval for mean
value generation
This parameter specifies the observation time period for mean value generation during power
measurement (see page 50). Acquisition is synchronous to clock time, for which reason the first
mean value usually does not span the entire specified duration.
