包络模拟和时间波形

您好，我是ADS的新手，我正在尝试使用它来评估第三人设计的RF 电路的响应。
基本上我有设计，我已经添加了我的时域源，我已经配置了从我以前在 matlab中生成的数据集中检索信号。
我要做的是测量功率放大器的输出电压。
我的时域源读取的数据是复杂的基带信号，我用600 MHz采样，并且我正在输入IQ调制器（调谐）以在900 MHz的载波频率下混合它们。
我会发现在时域中更容易运行模拟，但不幸的是，只要我通过信封模拟它，电路的一部分就可以传送数据。
现在我的问题是，当我简单地将电路的一部分用于为我的PA产生RF信号时，如果我尝试读取基带波形，或者还输出RF信号，我看不到我所期望的。
如何从此表示中获得正常波形？
（实际信号，因为我和Q分开喂养）。
第二个问题是关于源，我在帮助页面上看到包络模拟可以使用时间和频率源，所以在这种情况下，如果我使用电压定时源，它是否正常？
任何好的提示将非常感激。
BR，Giovanni

Hello,

I am completely new to ADS, and I am trying to use it in order to evaluate the response of an RF circuit designed by a third person.
Basically I have the design, and I have added my time domain sources which I have already configured to retrieve signals from a dataset that I have previously generated in MATLAB.
What I am trying to do, is to measure the output voltage of a power amplifier.
The data read by my time domain sources are complex baseband signals, which I have sampled with 600 MHz, and that I am feeding into an IQ modulator (tuned) to mix them at a carrier frequency of 900 MHz.

I would have found easier to run the simulation in time domain, but unfortunately a part of the circuit can deliver data just if I simulate it by the envelope.

Now my problem is that, when I simply take the part of the circuit generating the RF signal for my PA, if I try to read the baseband waverform, or also output RF signal I don´t see exactly what I would expect.

How can I get from this representation to my normal waveforms? (real signals since I and Q are feeded separately).

The second question is about the sources, I have read on the help page that the envelope simulation can use both time and frequency sources, so in this case is it alright if I am using the voltage timed source?

Any good tip will be very appreciated.

BR,
Giovanni
