H7216A/B-206 Introduction to Digital RF Communications

Audience: Test technicians and test engineers new to the area of RF and microwave.

This course teaches the basics of vector modulation, effectively the basics of digital modulation. The principles are explained using practical examples. Propagation effects and equipment impairments are simulated and measured.

What you will Learn

• Digital modulation principles
• Basics of digital cellular systems and digital communications
• Have an understanding of the cellular system concept
• Digitizing the baseband signal
• Multiplexing intro structures

Prerequisites

• Students should have either completed RF Measurements Basics (H7216A#101) course or have an understanding of electronic basics and of RF measurements.
