7.2.8 Time Domain Power Measurement
The Time Domain Power measurement determines the power of a signal in the time
domain.
A time domain power measurement is only possible for zero span.

7.2.8.1 About the Measurement
Using the Time Domain Power measurement function, the R&S FPL1000 determines
the power of the signal in zero span by summing up the power at the individual mea-
surement points and dividing the result by the number of measurement points. Thus it
is possible to measure the power of TDMA signals during transmission, for example, or
during the muting phase. Both the mean power and the RMS power can be measured.
For this measurement, the sample detector is activated.
7.2.8.2 Time Domain Power Results
Several different power results can be determined simultaneously:
Mode Description
Peak Peak value from the points of the displayed trace or a segment
thereof.
RMS RMS value from the points of the displayed trace or a segment
thereof.
