6.2.1 Accessing the Spectrum Mode
1. Press the [MODE] key.
2. Select "Spectrum".
A power vs frequency (spectrum) diagram is displayed, and the spectrum of the
currently captured data is analyzed, if available.
6.2.2 Display and Control
The Spectrum display shows a power vs frequency (spectrum) diagram and relevant
analysis parameters. Spectrum results are useful to obtain an overview of the input sig-
nal in the frequency domain and to detect unusual signal effects (such as spurs or dis-
tortions) visually.
The power levels in the diagram are always scaled logarithmically. The frequency axis
can be displayed either logarithmically or linearly.
Various statistical evaluations can be performed and displayed simultaneously. In this
case, the different traces are displayed in different colors:
●
Currently calculated spectrum: cyan-colored trace (like basic FFT)
●
Min hold and max hold evaluation: blue trace
●
Averaged spectrum: magenta-colored trace
Optionally, markers can be activated to indicate peak values in the spectrum. Track
cursors are available to determine the power or power density in a specific frequency
range.
