Signal generator1/14/2024 ![]() The signal generator can modulate this sinusoidal waveform (i.e., carrier signal) to carry information using frequency modulation, amplitude modulation, and phase modulation schemes. The RF signal is often a sinusoidal waveform at a determined frequency and amplitude. RF Signal GeneratorĪn RF signal generator, or signal generator, is a source that outputs an RF signal (loosely defined as 20 kHz to 300 GHz). Let’s take a closer look at each of these signal sources. In addition, the AWG is helpful for general purpose applications and the pulse generator is ideal for high-speed digital communications. There is the RF signal generator, commonly referred to as a signal generator, for wireless testing and function generator, for low frequency applications. There are several types of signal sources that generate electrical signals for testing. \įigure 1: The stimulus-analysis test model Types of Signal Sources For example, can an arbitrary waveform generator (AWG) replace an RF signal generator? Can you use a function generator instead of a pulse generator? We will answer these questions in this post. Choosing the right signal source can be confusing because signal sources have overlapping capabilities and features. There are many types of signal sources, each with unique capabilities and limitations. ![]() ![]() Signal sources are also used to simulate real-world stimuli to test a device’s performance in a realistic environment (Figure 1). Signal sources are an important component in many test systems and are designed to provide a source of “clean” or near ideal signals so that distortions do not influence the test results.
