Theory of signals and their spectra, how a spectrum analyzer works, and how to make typical measurements in satcom systems. Includes live, interactive spectrum analyzer simulator.
Essential concepts and skills for understand how spectrum analyzers display signals, typical instrument controls, and common satcom measurement techniques. In this course we will review essential theory of signals and their spectrums using interactive 3D time-frequency graphs, learn how a spectrum analyzer works with live animations, and discuss how to make typical measurements in satellite communications systems. You will be using a live, functional, interactive spectrum analyzer simulator for tutorials, skills practice, and skills assessments.
Prerequisites:GVF 520 recommended.
Audience:Engineers and technicians who use spectrum analyzers or who wish to learn about spectrum measurement theory.
Delivery:Animated & interactive HTML/Flash, self-paced, on-line format. Requires Internet access while studying the course material. High speed access is preferred but is NOT required. Student's computer must have a current browser and the current version of the Adobe Flash player (free) installed.
Tests:Each lesson contains a mandatory quiz. The third lesson also includes randomized skill assessments using the fully-function spectrum analyzer simulator. All pages must be viewed and all quizzes and simulator tests must be passed in order to successfully complete the course.
Experiment with a real-time 3D interactive animation showing waveforms simultaneously in time domain and frequency domain.
This interactive block diagram simulator shows how the spectrum analyzer processes the incoming signals for display. The student gains an intuitive understanding of the internal functions of the analyzer by experimenting with manual control of the filters and sweep circuit.
The fully-functional spectrum analyzer simulator includes controls for center frequency, span, level, dB/div, RBW, VBW, trace averages, marker, and reference line. It is used to teach and test important measurement skills.
