Key Characteristics of Signal Generators
and Modulation Methods
August 17, 2018 - Rohde & Schwarz USA (R&S USA) is now
offering this free "Key Characteristics of Signal Generators and Modulation Methods: Pocket
Guide." Register for this pocket guide to receive fundamental information on analog
and digital modulation methods. The Pocket Guide is available as a spiral bound hard
copy (no PDF for download at this time). The guide also provides important signal generator
specifications and parameters that should be considered when choosing a signal generator.
This is another in a series of Pocket Guides being offered by R&S. The "RF Component Pocket Guide," introduced earlier this year, is
Rohde & Schwarz also has a downloadable PDF file titled, "Modulation and Signal Generation with R&S® Signal Generators Educational
Note Products." Signal generators play a vital role in electrical test and measurement.
They generate the test signals that are applied to components such as filters and amplifier,
or even to entire modules, in order to ascertain and test their behavior and characteristic
s. The first part of this educational note presents the applications for and the most
important types of signal generators. This is followed by a description of the construction
and functioning of analog and vector signal generators. To permit a better understanding
of the specifications found on data sheets, a closer look at the most important parameters
for a signal generator is provided.
Beyond the output of spectrally pure signals,
a key function of RF signal generators is the generation of analog - and digitally modulated
signals. The second part of this note therefore presents the fundamentals for the most
significant analog and digital modulation methods.
The third part of this educational note contains exercises on the topics of analog
and digital modulation. All described measurements were performed using the R&S ®
SMBV100A vector signal generator and the R&S ® FSV spectrum analyzer. "
