我想生成一个LFM信号。
参数列表如下:载波频率:2 GHzBandWIdth:80MHz脉冲宽度:20μs如何生成信号,将波形文件下载到E8267,用matlab编程?BandWidth是E8267的最大BandWidth的80 MHz。 它会导致光谱失真吗? 如何用MATLAB解决这个问题? 以上来自于谷歌翻译 以下为原文 I want to generate a LFM signal. The Parametres list as follow: Carrier frequency : 2 GHz BandWIdth :80MHz Pulse width:20μs How to generate the signal, download the wave files to E8267, programming with MATLAB? The BandWidth is 80 MHz that the max BandWidth of E8267. Could it result in Spectral distortion? How to solve this problem with MATLAB? |

Hi -Matlab确实具有允许您创建此LFM信号的功能:载波频率 - 2GHzBandwidth - 80MHzPulse宽度 - 20usRather而不是通过复杂的信号创建细节我建议查看Matlab文件交换页面:http:// www
.mathworks.com / matlabcentral / fileexchange /从这个页面搜索LFM,这应该举例说明如何创建LFM信号。除了Matlab,你还需要Matlab信号处理工具箱和波形下载助手。波形 下载帮助可在以下网址找到:http://www.home.agilent.com/agilent/fac ... btn = SearchOnce您已创建波形,使用波形下载助手将LFM波形下载到E8267D中。您是对的 因为E8267D指定的I / Q带宽为80MHz,但实际带宽延伸得更远。 因此,根据上述信号,由于带宽限制,您应该没有频谱失真。注意 - 相关产品:#E8267D# 以上来自于谷歌翻译 以下为原文 Hi - Matlab does have features that will allow you to create the this LFM signal: Carrier frequency – 2GHz Bandwidth – 80MHz Pulse width – 20us Rather than going through the complicated details of signal creation I recommend checking out the Matlab File Exchange page: http://www.mathworks.com/matlabcentral/fileexchange/ From this page do a search on LFM and this should give examples on how to create the LFM signal. In addition to Matlab you will need the Matlab Signal Processing Toolbox and the Waveform Download assistant. The waveform download assistance can be found at: http://www.home.agilent.com/agilent/fac ... btn=Search Once you have created the waveform, use the Waveform Download assistant download the LFM waveform into the E8267D. You are correct in that the E8267D specified I/Q bandwidth is 80MHz but the actual bandwidth extends much farther . So with described signal above you should have no spectral distortion due to Bandwidth limitations. Regards - Relevant Products:#E8267D# |
