I'm using Spectrasys to do some transmit line up calculations. I've built a simulation of the transmit lineup, and I'm looking at the spectral plot at the output. There are quite a few traces there, that I assume are contributions from each of the blocks in the simulation. How can I

1-Tell which block is contribuiting which trace

2-Get a single trace that shows the overall output spectrum?

This is in Genesys 2008.07 SP1
Thanks

Dave

After some more poking around, I found the answer to #1. I was plotting dBm(p2) (Port 2 is the output port). Changing the graph to plot just P2 fixed that, and now i'm getting an identification of which block contributes which spectral component.

Still not sure of #2, though.

Go into the "composite spectrum" tab in the system simulation setup dialog. I think the rest should be self explanatory.
