Description

technical field [0001] The invention relates to the detection field, in particular to an intermediate frequency signal acquisition and analysis device and method. Background technique [0002] The research on intermediate frequency signals is becoming more and more extensive. When analyzing the obtained intermediate frequency signals, signal engineers are not limited to observing the time domain waveforms in the past. They often need to further observe and analyze the signals, so as to obtain more real signals. Characteristics. [0003] The main function of the intermediate frequency signal acquisition and analysis device in the prior art is simply to display the waveform of the signal, and there are not many functions for further analysis of the signal. And has the following deficiencies: [0004] 1. If it is necessary to amplify and filter the signal at a fixed value and then analyze it, the selection of amplification factor and filtering frequency can only be carried ou...

AI Technical Summary

Problems solved by technology

[0004] 1. If the signal needs to be amplified and filtered at a fixed value before analysis, the selection of amplification factor and filtering frequency can only be carried out in the digital signal link, and the lack of amplification and filtering in the circuit link limits the relevant analysis functions;

[0005] 2. The use function has been fixed, it is difficult to expand the use function, and the analysis flexibility is limited;

[0006] 3. When measuring tiny signals, they are often overwhelmed by noise and cannot obtain the characteristics of the signal;

[0007] 4. Some devices are heavy and poor in portability

[0008] It can be seen that the intermediate frequency signal acquisition and analysis device in the prior art still has many deficiencies and needs to be improved
