The number panel for

ing the power range to the trace.
Background information
The time resolution of the trace is determined by the length of the measurement window and the num-
ber of measurement points (
Switching the sensor to the Scope mode, p. 4.41). A measurement point
therefore represents the power for a time interval within which the test signal can considerably vary.
Among the different ways of finding a representative value, each measurement point is assigned the
average power of the correlating time interval, which can result in deviations from the expected charac-
teristic of the envelope power. In this case, the time resolution must be increased by shortening the
measurement window and/or raising the number of measurement points.
This aspect should be given special attention, especially when measuring the peak power and the
Peak/Avg ratio (
Meas, p. 4.47).
T’slots
On this page of the Scope mode display, a timeslot structure – the configuration that was defined for the
Timeslot mode in the Mode menu – is blended into the power characteristic (
Measuring the power of
TDMA signals, p. 4.13). In addition, the average power of a timeslot that can be selected from this is
displayed, taking into account the exclude times. As the exclude times on the set page can be changed,
the effects on the measurement result can be seen immediately.
