EST for LEARNING OUTCOMES
In the previous experiments, we introduced the concepts
behind phase locked loops, amplitude modulation and
frequency modulation, and we now have a good understanding
of them. But that is not enough to fully grasp RF circuits. This
experiment combines these three parts to form one system.
Each module in the circuit can be turned on or off via remote
commands so that the experiments can be used to diagnose
(simulated) malfunctions. When students analyze the causes of
these malfunctions, they will have an overall understanding
about the relationship and principles behind each one. This
helps students build their knowledge of PLLs, AM and FM.
Experiment
Aim:
1.
Understand how and why a phase locked loop enters the lock
state or loses the lock state.
2.
Have an understanding of the overall communication system.
Experiment
Contents
The instructor will send remote commands to the GRF-1300 and
create a malfunction. Students can use an oscilloscope, spectrum
analyzer and/or other measurement instruments to try to
deduce/verify the cause of the malfunction/fault.
