With the requirement of radio technology developing, the weakness of traditional receivers is more and more serious. We choose a wide-band portable receiver to research, which can offer IQ data output and be controlled by computer software. At ifrst, we brielfy introduce the basic parameter, then compare the function and characteristic of three different software. Finally, we give the correct way of getting IQ data.
