Description
The MEANPWR command measures the average power of the carrier
during that portion of the time when it is on. The on state is defined as
the time when the signal is within a selected number of dB of its peak
level. The range of amplitudes that is defined as the on state can be set
with the command. The amplitude range is set relative to the peak
value of the signal. The CARRON command is similar except that it
doesn't allow definition the range of powers that are the on state.
The reference level and input attenuation are set automatically based
on the measured power level of the carrier. Several sweeps are used to
measure the true mean carrier power. True mean carrier power is
calculated by measuring the time waveform of the RF envelope,
converting the trace data from dB to power units, and then averaging
the power trace data.
Parameters
