What is a signal generator?
A signal generator is an electronic device that generates signals in different properties such as amplitude, frequency, and wave shape. Signal generators are mostly used for test and development systems. They exist many different types of them each one provides a different form of signal. Some provide Radiofrequency signals, audio signals, some can provide different shapes of waveform and others may provide just pulses.
Logicbus is a leading technology in industrial engineering. Thus, its they, have a wide range of applications from replicating sensor signals to creating high-speed serial data or RF(radio frequency) signals with digital modulation applied.
What are the different types of signal generator?
They exist many different types of signal generators:
-
Standard signal generator
-
This is the most common type, and it can produce both repeating and non-repeating waveforms in a diversity of amplitudes and shapes. These are commonly available and are also applied for educational purposes everywhere around the world.
-
-
Radiofrequency signal generator
-
Also, know an RF frequency is used to produce signals in a specific range of bandwidth. The range of a typical RF signal generator is from 10 kHz to 6 GHz. These instruments also typically provide normal analog modulation such as AM, FM, and PM. They are used for testing components, receivers, and test systems in a wide variety of applications including cellular communications, WiFi, WiMAX, GPS, audio and video broadcasting, satellite communications, radar, and electronic warfare.

-
Analog Signal generator
Analog signal generators were based on sine-wave oscillators and were the most popular before the arrival of digital electronic tools. They were used to measure radio frequency and audio frequency.
-
-
Function / arbitrary waveform generators use advanced Digital Frequency Synthesis (DDS) technology to produce high-quality standard function and arbitrary waveform signals. They also provide a wide range of analog and digital modulation functions.

-
Special function signal generators
- Pulse-generators
- Video
- Digital pattern generator
Frequently asked questions:
Question:
1.What is used for?
Is used when you need low phase noise or an accurate power level in your signal.
2. Oscilloscopes are signal generators?
Oscilloscopes are a type of signal analyzer that shows the experimenter a picture of the signal, usually in the form of a voltage versus time graph.
