(OP)
The attached simulink file is a very simple model of a signal source with a scope and spectrum analyser attached.
The signal source produces a constant value of 1 over the entire simulation time. The spectrum analyser has been setup with a HANN window.
From the spectrum analyser you can see the value at zero hertz is 30 dBm. With Hann windowing I was expecting the value to be about 6 dBM less than this ?
For simple signal analysis such as this I find simulink incredible difficult. Any suggestions for easier to use signal processing software would be more than welcome.

Why don't you try putting a few frequency sources in your window? That way you can see if your window shape is behaving as you expect.

If you want to input a pulse, you should adjust the parameters Pulse Generator>Pulse Width and Pulse Generator>Phase properly.
