An RF generator (HFG, High Frequency Generator) is a device that is supplied with direct current, and an alternating high-frequency current is removed at the output. They can be in the video of individual devices – this is how they are used in professional electronics. But most often, generators are not made as separate devices, but are included in various circuits and are located directly on them. They are used in almost all circuits – like local oscillators in radio receivers, they are very often used in measuring technology to test various radio elements. But they are most widely used in computing. There they are used as master (clock) generators that form clock pulses of various frequencies to synchronize the passage of signals from one device to another.
Data transmission would not be possible if the generators did not generate clock pulses to avoid sending a packet at the wrong time. RF generators are used to produce electrical oscillations in the frequency range from tens of Hz or kHz to tens or hundreds of MHz. Some models can generate frequencies in the gigahertz range. Also, the RF generator is the most basic unit of any transmitter. With it, a carrier wave is created, on which a useful signal is then superimposed. RF oscillators are most often designed using LC oscillatory circuits or quartz resonators as those elements that set the frequency. If necessary, the oscillatory circuits in some generator circuits can be easily replaced by quartz resonators – sometimes they are interchangeable.
Working with the generator most often consists in setting the frequency that it will generate. To do this, use the knobs on the front panel of the device.
