How much do you know about the type of signal generator?

Speaking of signal sources, hardware engineers must be very familiar with them. Like spectrum analyzers and oscilloscopes, they are common test instruments for product development in the electronics and information communications fields. A signal source, also called a signal generator, is an electronic device that can generate electronic signals in the analog or digital domain. It is mainly used for research and development, testing, problem location and repair of electronic equipment.

A series of function generators produced by HP from the 1950s to the 1970s. The Arbitrary Waveform Generator (AWG) is a complex signal generator that can achieve high performance in frequency range, accuracy and output level. Generate arbitrary waveforms within the range. Unlike a function generator that produces a specific set of waveforms, an AWG allows the user to specify an arbitrary source waveform as the output in a variety of different ways. Typically more expensive than function generators, AWGs are primarily used in high-end design and test applications. AWGs offer unparalleled flexibility, speed, and fidelity, making them an ideal solution for high-speed serial, optical communications, radar testing, and electronic warfare. plan.

Tektronix 7122C Arbitrary Waveform Generator RF & Microwave Signal Generator RF & Microwave Signal Generator is used to test various applications including cellular communications, WiFi, WiMax, GPS, broadcast, satellite communications, radar and electronic warfare. Components, receivers and systems. RF and microwave signal generators often have similar characteristics and capabilities but different frequency ranges. RF signal generators typically range from a few KHz to 6GHz, while microwave signal generators cover a wider frequency range, from 1MHz to at least 20GHz. Some models can achieve direct coaxial output up to 70 GHz, or up to hundreds of GHz when using an external waveguide source module. RF and microwave signal generators can be further classified into analog signal generators and vector signal generators. Analog Signal Generator Analog Signal Generator based on sine wave oscillator was common before the birth of digital circuits and is still in use today. RF analog signal generators are capable of producing continuous wave tones. The output frequency can usually be tuned anywhere within its frequency range. Some models offer various types of analog modulation, which may include AM, FM, phase modulation, and pulse modulation. Another common feature is a built-in attenuator, which changes the output power of the signal. Depending on the manufacturer and model, the output power of an analog RF signal generator can range from 135 to 30 dBm.

Keysight E4428C ESG Analog Signal Generator Vector Signal Generator With the emergence of digital communication systems, it is no longer possible to test these systems with traditional analog signal generators. This led to the development of the Vector Signal Generator. These signal generators are capable of generating digitally modulated radio signals using a wide range of digital modulation formats such as QAM, QPSK, FSK, BPSK and OFDM. Furthermore, because modern commercial digital communications systems are almost always based on well-defined industry standards, vector signal generators can generate signals according to these standards. In contrast, military communication systems such as JTRS place great emphasis on the importance of robustness and information security, often using proprietary methods. To test these types of communication systems, users often create their own custom waveforms and download them into a vector signal generator to create the required test signals.
