如何在CST MWS里導入雙指數(shù)激勵源，指點

CST微波工作室里沒有雙指數(shù)激勵源，本人想通過數(shù)據(jù)導入，敢問應該導入的數(shù)據(jù)是什么樣格式?試了一下excel和txt，老是出現(xiàn)不能讀取，求高人指點一下，我應該如何導入??！

小編你所說的雙指數(shù)是不是Double exponential?
如果是，CST MWS里已經(jīng)有了。 CST MWS幫助文件《Excitation Functions》。
至于導入，請善用軟件的幫助文件，CST MWS幫助文件《Excitation Signal》：
Alternatively, it is also possible to import an ASCII file containing signal data points.
Note: A user defined excitation function must first be edited inside the integrated VBA-editor. The related VBA-macro is created and opened by the editor via the Edit... button. After finishing the editing process, please make sure that the VBA-macro is saved to file.
To import a table with signal data points, use the Browse... button and select a text file with a two-column signal description, where the first column represents the time values in seconds. Please note that you have to activate the Import signal type to enable this functionality.
Imported and user defined signals are always interpreted in the unit seconds.
