有關(guān)monitor時域分析

天線設(shè)置激勵頻率CST在做天線的時域分析，想的是用field monitor來分析，選擇time那一項就可以了，可是卻沒有任何結(jié)果，不知道為什么。。。。。請高手賜教，多謝！
后面附有截圖，我設(shè)置有問題，我選的激勵是高斯脈沖，頻率01G，多謝多謝

monitorw 都是在頻域中用的

那就是不能用那個time了？那是不是只能用probe和voltage monitor？新手初學(xué)，請多多指教！

If you want to use the field monitors in time domain, then the monitor records the chosen field type at several equidistant time samples. Note thatthis feature is not available for farfield monitors for frequency domain solvers.
Step width: Enter here the desired step width for the time monitoring. Together with start and end time this value determines the full number of recorded time samples. Note that time monitors possibly need a great amount of disk memory if the step width is chosen too small.
End time: Selecting this check box offers the possibility to define a specific endtime for the recording. If it is not selected, the recording will continue up to the end of the calculation.

Thank you very much!Then I still have one question.When I choose the step width too small,I can see this warning:.......has an extremely high sampling rate!What does that mean?And should I change some settings?Thankyou!!!!

You can type in Chinese. The administrator has no idea how to active the Chinese input on my workstation so I can read but cannot type......
Like what the CST help says, "Note that time monitors possibly need a great amount of disk memory if the step width is chosen too small". Then just increase the value of step width until the warning message disappears.

SorryI thought you'd like to talk in English.多謝
