Monitoring signal characteristics
The R&S
SMM100A is a highly configurable signal generator with level settings distrib-
uted over several dialogs. To optimize the signal generation process and to help moni-
toring the variation of the signal parameters through the instrument, the
R&S
SMM100A is equipped with a real time graphical signal display. This section
explains the provided functions for monitoring of the signal characteristics in real time.
Here you can also find out how to visualize the generated signal with measurement
diagrams.
8.1
Displaying baseband signal characteristics in real-
time
In test setups, you usually use signal and spectrum analyzers or an oscilloscope to dis-
play and analyze the characteristics of the generated signal. In the R&S
SMM100A,
you can also use the built-in graphical signal display function and visualize a subset of
signal characteristics.
8.1.1
Required options
The minimum equipment layout for using this function includes the base unit.
8.1.2
About the graphical signal display
To ease the setting and routing of baseband signals, R&S
SMM100A is able to capture
these signals and display them graphically in different ways: as I/Q, vector, eye or con-
stellation diagram, as power spectrum or as statistical evaluations.
In the digital domain, the measurements are based on recorded I/Q samples. The
sources of these samples are selectable points (acquisition points) in the signal flow.
You can configure and display the signal characteristics simultaneously in up to dia-
grams.
