![]() We support customers after the sale by providing responsive US-based technical support and a 90 day “no questions asked” return policy.The standard models produce sine waves from DC to 2.025 GHz (SG382), 4.05 GHz (SG384) and 6.075 GHz (SG386). What are the warranty and support options available for the RF signal generator DC usually refers to a specific voltage, such as the 1.5Vdc that comes from a traditional alkaline AA battery. DC, or Direct Current has no variation, or at lease has no periodicity. ![]() It usually has a periodicity, which means its voltage and current cycle (alternate) at or around particular frequency. These devices frequency ranges usually cover 20Hz to many Megahertz, are lower cost and will usually create time domain waveforms in the shape of sinusoids, square waves, triangles and saw tooth waveforms. ![]() IQ modulator combined with a radio up-converter.They can be expensive and require expertise to operate. These can generate very complicated signals across the RF spectrum. Unfortunately they can become cost prohibitive much above 1GHz and use quite a bit of current. These are Direct Digitally Synthesized devices that can be very clean and agile. These cover very large frequency ranges and have been discussed above. There are a few different types of signal generators. What are the different types of signal generator? While circuits in an AF Generator can be somewhat complex, RF Signal Generators can be very complex. What is the basic difference between AF signal generator & RF signal generator?Īn AF Signal Generator is a low frequency generator and an RF Signal Generator generates much higher frequencies. In both cases AF and RF can, of course, be carried on a wire. While 3 KHz up to 20 KHz is considered part of the audio frequency band, it can also be carried in the electromagnetic field and transmitted as RF! This usually requires a very long antenna. The RF frequency band is generally considered to be 3,000 Hz up to 300 GHz (300 with nine zeros). Audio frequency refers generally to the frequency band that our ears can hear which is usually considered 20 Hz through 20,000 Hz. AF stands for Audio Frequency which propagates through the air molecules around us. RF stands for Radio Frequency, which is a signal that propagates through the electromagnetic field around us. The frequency stability is determined by the reference frequency (Fref), which usually comes from a lower frequency crystal based oscillator. The PLL is a control system that measures the phase (and frequency) of the VCO while concurrently adjusting the voltage of the VCO so that frequency stability is achieved. A VCO will drift in frequency and have significant noise called phase noise if it is not nicely controlled. ![]() The VCO oscillates and makes an RF signal that is tuned in frequency by a control voltage. RF Signal Generator Frequently Asked QuestionsĪn RF Generator creates radio frequency signals using high speed voltage controlled oscillator (VCO) circuits combined inside a phase locked loop (PLL). See how we test our RF signal generators for Reliability The robust design and high-quality components ensure reliable signal generation, minimizing signal drift and fluctuations. With a solid reputation in the industry, these signal generators offer consistent and stable performance, making them a trusted choice for various applications. We support customers after the sale by providing responsive US-based technical support and a 90 day “no questions asked” return policy. We pride ourselves on keeping products in stock and shipping within just a few business days. The spectrum of applications ranges from wireless communications devices and automated test equipment to quantum computing experimentation and production. They are used anywhere engineers, technicians, or scientists might need an RF Signal Generator for either experimentation or production of high volume equipment. Our signal generators have been implemented by major corporations, small companies, startups, universities, contractors, militaries, and government agencies around the globe. Windfreak Technologies’ RF signal generators are designed to emphasize reliability, low cost, and small size without sacrificing features like high calibrated RF power, great phase noise, modulations, RF sweeping, RF hopping, hardware triggering, UART control, and more.įor over a decade, our RF signal generators have been routinely used in place of large benchtop products by Keysight, Rohde & Schwarz, and other high-cost competitors.
