RF signal generators produce high-frequency signals in the radio frequency spectrum, which may range from a few kilohertz (kHz) to high power outputs of several gigahertz (GHz). They are waveform generators used for testing and measuring equipment in electronic testing, telecommunications, audio and video, as well as automotive applications.
RF signal generators create precise radio frequency signals by generating waveforms at specific frequencies and amplitudes. Their core components include:
Modern RF signal generators often incorporate digital signal processing (DSP) to generate arbitrary waveforms and complex modulation formats, enabling realistic simulation of wireless communication signals.
Also known as function or wave generators, these basic RF signal generators produce simple, repetitive waveforms. Both professionals and students utilise these generators for basic troubleshooting of electronic devices.
Arbitrary Waveform Generators (AWGs) and Function Generators are both capable of generating standard to intricate waveforms. Thanks to their ability to simulate complex 5G signals, Arbitrary Waveform Generators play an important role in the testing and development of modern 5G networks.
High-frequency RF Signal Generators and RF Vector Signal Generators represent the gold standard for RF testing. Vector Signal Generators, in particular, are able to add complex modulations to waveforms it generates, which allows for more realistic mobile device or radar systems testing.
USB or computer-controlled signal generators are used to generate high frequency signals over a broad frequency spectrum. They are commonly used for testing Wi-Fi, GPS, satellite communications, and other wireless systems requiring flexible, portable solutions.
The deployment of RF signal generators are critical for integrated electronics testing, like that of RF integrated circuits (RFICs) and modules. Signal generators are also used to calibrate the RF front-end module of smartphones, so that a high degree of Wi-Fi, Bluetooth, and mobile communication functionality can be accounted for.
Many modern embedded systems, from Internet of Things (IoT) devices to automotive electronics, incorporate RF transceivers.
RF signal generators are needed to test for receiver sensitivity, verify data transmission and reception, measure antenna performance, and debug wireless protocols.
RF signal generators are used to measure the performance of digital circuits which incorporate RF interfaces and those that operate at high speeds. For instance, the ability of RF signal generators to produce high-frequency data streams is utilised for the testing of Serialiser/Deserialiser (SerDes) interfaces.
The development and testing of analogue signal processing circuits and systems wouldn't be possible without RF signal generators. They are used for characterising filters, testing amplifiers, evaluating mixers and frequency converters, as well as assessing modulators and demodulators.
RF signal generators are ubiquitous across research and development labs of various scientific and engineering disciplines. For example, they can be used for electromagnetic compatibility testing, to generate controlled interference signals to determine a device's suitability for pre-compliance testing.
