| Abstract: | For the requirement of the spectrum measurement in outdoors,the design of a handheld spectrum analyzer is brought forward.Adopting the Software Radio designing idea,AD sampling is taken after the super heterodyne module. By realizing all of the spectrum function in digital domain,the volume and power dissipation are significantly reduced,so that a good performance handheld spectrum analyzer is realized. |
