What is the difference between vector signal source and radio frequency signal source?

Release time:


Vector signal sources and radio frequency signal sources are devices used to generate radio signals, but they are different in the way and applications of signals.

Vector signal source is a programmable, digital signal generator that can generate baseband signals, intermediate frequency signals and RF signals. Vector signal source can generate complex modulation signals, such as QAM, PSK, FSK, etc., can also be used to generate various signal simulation, such as radar, communication, broadcasting, etc. Its advantage is that it can accurately simulate complex signals and can process and modify the signals in the digital domain.

The radio frequency signal source is a device that generates radio frequency signal, which is mainly used for testing and measurement. The radio frequency signal source can generate signals such as single frequency, frequency adjustment, and amplitude adjustment, and can be used to test radio frequency circuits and radio devices. The advantage of the radio frequency signal source is that high -frequency signals can be generated, and they have high precision and high stability.

In general, the vector signal source is suitable for application scenarios that need to generate complex signals, such as communication, radar, etc.; and the radio frequency signal source is suitable for application scenarios such as testing and measurement.
