In multi-gated acquisition mode, the measured values of different gates are dis-
played as separate submeasurements, i.e. not combined in one result as in the
gated mode. However, the submeasurement results for the same gate index
performed in consecutive repetition windows are combined to smoothen RMS
and peak power depending on measurement duration / sweep time.
Note: We recommend that you configure up to 32 submeasurements per mea-
surement, i.e. 32 gates in a repetition window. The repetition window is defined
by marker 2 and has to be longer than 100 ms.
This acquisition method is suitable for power measurements on burst signals or
pulse signals with different duty cycles. Like, for example, measurement on a
periodic signal composed of a preamble, sounding channel and data, where
each of these three fields is transmitted with different power.
The displayed power values are suitable as control mechanism. The values cannot be
modified to influence the power and level control in the instrument.
A combination of different measurements acquisition methods can be enabled at each
acquisition point. The measurement results are displayed simultaneously in a list.
Refer to Chapter 9.2.4, "How to Query Information on the Baseband Power Levels",
on page 630 for examples on using the provided acquisition methods and their appli-
cation fields.
9.2.2.4 Understanding the Displayed Measurement Results
The following rules apply by the calculation and display of the measurement results:
●
The displayed power values refer to the selected Output
●
As a reference value serves the 0dBFs level.
●
The results are displayed in the current units of the corresponding Output
For example, if an R&S SGT is connected to one of the DIG I/Q Out interfaces, the
results are displayed in dBm; the instrument name is also indicated.
