CST MWS和DS聯(lián)合仿真Task中Transient和S-parameters的區(qū)別？

看起來(lái)兩個(gè)都可以算S參數(shù)，CST里面的范例兩個(gè)都是有用的，那么請(qǐng)問(wèn)要在微帶里加上三極管偏執(zhí)電路應(yīng)該用哪個(gè)TASK?

CST DS幫助文件《Simulation Task Overview》：
S-Parameter Simulation Task
This type of task defines an S-parameter simulation. S-Parameter describe the electrical small signal behavior of a device in the frequency domain. They are calculated for your model with respect to external ports. Consequently, your design must contain at least one of them. After the successful execution of a task, the results can be accessed below the associated task item inside the navigation tree. This applies to all types of simulation tasks.
Transient Simulation Task
CST DESIGN STUDIO™ is also able to perform simulations in the time domain. In contrast to AC/S-Parameter tasks a transient simulation properly considers all existing nonlinearities of the circuit. Since simulated and measured blocks as well as most of the standard blocks available are described by frequency domain data, equivalent time domain descriptions are automatically created for them during the execution of transient simulation task.
Sources for this type of task are defined via external ports. These can either be voltage, current, or so-called signal sources. The last ones emulate a (waveguide or discrete) port excitation of CST MICROWAVE STUDIO® in order to make possible easy comparisons between results of CST DESIGN STUDIO™ and CST MICROWAVE STUDIO®.
There are several signal types available in CST DESIGN STUDIO™, among them common ones like sine and pulse, and even bit sequences. For the latter ones, eye-diagrams are generated during the simulation.
In addition to the AC simulation task, the transient task is also able to provide the Combine results feature (see below). Note that the excitations defined by the sources contained in your model will be considered there.
所以只要能得到你想要的參數(shù)，用哪個(gè)都可以。

兩個(gè)不一樣，我后來(lái)思考了一下：瞬態(tài)求解器是特定信號(hào)的S參數(shù)，S參數(shù)求解器是真正的S參數(shù)，

如果這個(gè)指定信號(hào)是高斯信號(hào)，兩個(gè)還有區(qū)別嗎?

小編留言：

有區(qū)別，而且不小
