Hello again Brian,
Well here is the screen shot.

The sample rate was set to 20 M, the frequency to 5 MHz
and the interpolation to 20. The WBX carrier was set to 1 GHz
I am sure I have done something wrong

You should definitely be able to see something at 1.001GHz, but any
residual DC offset will also cause a spike at 1.000GHz when using a
vector modulator.
What's your resolution bandwidth set at on your spectrum analyzer?
Can you post a link to a screen shot or two?
Brian
