NTRODUCTION to the GRF-1300
The GRF-1300 is a well designed training kit capable of
producing a 3MHz baseband signal and a carrier signal up to
900MHz. The GRF-1300 is also able to perform AM and FM RF
circuit experiments as well. The practical exercises in the
training kit meet the needs of most general RF courses. The
GRF-1300 consists of three modules, namely: a baseband
module, an RF Synthesizer/FM module and an AM module.
The baseband module can simulate a baseband signal and
includes sine, square or triangle waveforms. Its output
frequency and amplitude are adjustable. During experiments
the three kinds of waveforms can be arbitrarily switched back
and forth to meet the signaling requirements of each of the
different experiments.
The RF Synthesizer/FM module is used to generate an
adjustable carrier frequency as well as perform frequency
modulation. This module covers some of the focus points in the
RF circuit theory. This will be highlighted in practical
experiments in later chapters. FM waveforms can also be
produced by using this module together with the baseband
module. The GSP-730 spectrum analyzer can be used to observe
the various characteristics of an FM waveform.
The AM module and baseband module can be used
together to perform amplitude modulation experiments. The
GSP-730 Spectrum Analyzer can be used to observe the various
characteristics of an AM waveform.
This experiment system can be connected to a computer via
the USB interface. The interface can be used to turn individual
circuits on or off so that students can perform diagnostic
experiments.
Students can learn the fundamental aspects of RF theory
through a variety of experiments. Understanding RF theory has
been made easier by breaking the RF circuits into fundamental
functions. This allows students to see in detail how the theory
relates to the practical aspects of the RF circuitry.
This system is a collection of different functions: signal
generation, frequency modulation, amplitude modulation,
