Amplitude Modulation PathWave System Design (SystemVue) Schemes – Lab 1
技术概述
Introduction
Keysight Technologies’ Modulation Lab Series utilizes PathWave design software to help students develop an understanding of:
• Modulation schemes from a system level
• Modeling and simulating a communication system using PathWave System Design
Software Versions
The workspaces in these lab series were developed in Keysight PathWave System Design 2022.

Background for Students
In this set of exercises, you will create a variety of signals and visualize them in both the time and frequency domain using Keysight PathWave System Design, also known as SystemVue. A common SystemVue workspace is used for all the exercises. This is conceptually similar to a laboratory workbench comprised of a signal generator (the source) and signal analyzers (the sinks). The latter includes a time domain data sink which can be thought of as an oscilloscope and a frequency domain sink which is similar to a spectrum analyzer.
To begin with the exercises, it is assumed that you have a PC or laptop on which the suitable software has been installed.
Prerequisites
Students who are unfamiliar with any of the above aspects of SystemVue should take advantage of the on-line resources provided in Table 1 — a Keysight account might be required.

Wireless communication and modulation
In simple terms, it could be said that radio frequency, microwave, millimeter-wave and sub-THz-wave communication systems all rely on the following fundamental principles:
• an electromagnetic (EM) carrier wave—in essence a sinewave—can transfer energy from a transmitter to a receiver without using wires (hence the term “wireless”); and
• a modulated carrier can be used to transfer information. In other words, by continually altering or modulating the characteristics of a sinusoid, we can use it to transfer information wirelessly.
