I need to use the Ptolemy with Envelope simulation and I have some problems. The device in the PA is modeled using TOM model. In the test,I send a CW wave to the PA. I tried it in Envelope simulation and cosimulation of Envelope and Ptolemy (the CW signal is generated in Ptolemy and SpectrumAnalyzer is used to look at the signal). The results (output power level) are very different. Thanks.
Having said that I wonder why someone wants to send a CW signal through a transistor level block using Ptolemy?
