multiple timeslots ( Measuring the power of TDMA signals, p. 4.13).
The Timegate mode provides four user-configurable gates for meas-
urement ( Measuring power in gates, p. 4.14).
In the Scope mode, the R&S NRP records the power versus time and
displays it graphically. The time parameters of the Timeslot and
Timegate modes can also be interactively configured in this mode
( Analyzing the envelope power, p. 4.15).

Free-running average-power measurements
The Continuous Average mode is the preferred measurement method if the measurement is not to be,
or cannot be, synchronized with a specific signal event.
This is the only available measurement mode for thermal sensors because they are too slow for the
other measurement modes.

This parameter defines the duration of the measurement window. In
the manual mode, the default setting of 20 ms combined with smooth-
ing (see below) is usually adequate. Another value, generally larger, is
essential if the result exhibits fluctuations due to modulation. With very
low frequency modulation in particular, it is a good idea to set the size
of the sampling window so that it exactly equals the modulation period,
so ensuring optimal display settling:
