Understanding Vector Signal Generators

Signal generators are among the most important and most widely-used instruments in radio frequency (RF) test and measurement. The ability to create high-quality signals with a user-definable frequency, level, and modulation is an essential building block in many test scenarios, including component testing, device testing, and electromagnetic compatibility (EMC) testing. This educational note explains the fundamental principles of both analog and vector signal generators, their most common applications, and the different functionalities supported by each type of generator.
