9 Measurements and Result Displays
The measurements and result displays available in the Receiver application allow you
to analyze the frequency spectrum for possible interferers and the characteristics of
those interferers.

9.1 Performing Measurements
The R&S ESW provides several approaches to do measurements and acquire the sig-
nal data.

Performing continuous measurements
When you measure continuously, the measurement is repeated until you deliberately
stop it.
The duration of each individual measurement cycle (for example a single bargraph
measurement) depends on the
measurement time you have set for the measurement
in question. After each measurement cycle, the data of the previous cycle is overwrit-
ten and replaced by the new data. Exception: When you are using a max or min hold
function, the application keeps the highest or lowest values and replaces old data only
if the current data contains a new maximum or minimum.
The R&S ESW allows you to select the measurement mode for the bargraph and the
scan separately. When you select a continuous bargraph measurement, IF analysis
(including the spectrogram) is also performed continuously. When you select a continu-
ous scan, the scan spectrogram is also updated continuously. Running a continuous
final measurement is not possible.
▶
To start a continuous scan, press either the [RUN CONT] key on the front panel or
the "Continuous Scan" softkey in the "Sweep" menu.
▶
To start a continuous bargraph measurement, press the "Continuous Bargraph" soft-
key in the "Sweep" menu.
