CST MWS和DS联合仿真Task中Transient和S-parameters的区别？

CST DS帮助文件《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参数，用哪个都可以。

两个不一样，我后来思考了一下：瞬态求解器是特定信号的S参数，S参数求解器是真正的S参数，

如果这个指定信号是高斯信号，两个还有区别吗?

有区别，而且不小
