RF Communication and Signals Experiments
Experiment 7: Using a Spectrum Analyzer in Communication
Systems
Relevant
information
ACPR and OCBW are important parameters in the
measurement of RF modulated signals. It is very important to
master using a spectrum analyzer to measure ACPR and OCBW.
We must know how to utilize a spectrum analyzer to measure
the RF parameters that are frequently used and to lay the
foundation for future use. ACPR is the ratio of the amount of
power leaked to an adjacent channel from the main channel.
OCBW is the occupied bandwidth that contains a specific
percentage of the total integrated power of the channel. At
present, third generation mobile communication systems (3G)
are becoming ubiquitous, while some countries and companies
are looking to develop fourth generation mobile communication
systems (4G). This experiment, therefore, has a high practical
value for the measurement of CDMA RF power and related
fields.
