greetings,
I am trying to simulate a RF PLL (costas loop) demodulator. I am new to ADS, and I have been learning a lot, but I can't figure out how to get it to work. I am stuck on two things.
1. I am not sure how to create a PSK signal to put into my costas loop. I have been trying to create a sub-project to make the modulator, but I can't get anything to work. do I have to use a VCO, or can I just make a variable to flip between phases (0, 90, 180, ect)?
2. I am not sure how to do a simulation where I can just look at the time-domain RF signal (as if I was looking at an oscilloscope). how does one do this?
Thanks,
Cato
