The invention relates to the technical field of signal sources, in particular to a comb spectrum signal generator which comprises a shell, a cover plate, a circuit board, a power circuit, a crystal oscillator, a frequency conversion circuit, an amplifying circuit, a filter circuit and a combiner, and the power circuit, the crystal oscillator, the frequency conversion circuit, the amplifying circuit, the filter circuit and the combiner are arranged on the circuit board. According to the comb spectrum signal generator, the frequency signal is transmitted through the crystal oscillator, the frequency conversion circuit converts the frequency signal transmitted by the crystal oscillator into multiple paths of frequency signals needing to be set and outputs the frequency signals, and the multiple paths of frequency signals needing to be set are amplified through the amplification circuit and filtered through the filter circuit and then output through the frequency conversion circuit. The signals enter the combiner to be combined into one signal output; output signals are stable and high in power, meanwhile, the output signals are small in power difference, spectral line consistency is good, debugging is convenient, and power consumption is low. In addition, the whole circuit board is arranged in the closed metal shell, the shielding performance is good, and installation is convenient.
Description
technical field [0001] The invention relates to the technical field of signal sources, in particular to a comb spectrum signal generator. Background technique [0002] A signal source, also called a signal generator, is a device that can provide a specific frequency, waveform, and output power. When measuring the amplitude characteristics, frequency characteristics, transmission characteristics and other electrical parameters of various telecommunication equipment and systems, it is used as a test signal source or excitation source. According to the type of output signal, the signal generator can be divided into radio frequency signal generator, scanning signal generator, frequency combiner, noise signal generator, pulse signal generator and so on. The existing traditional comb spectrum signal generators mostly use harmonic generators, which have poor frequency stability and large differences in the power of each spectrum signal. [0003] In view of this, there is an urgen...
