Down Converter Measurement with 8722ES

I'm trying to characterize my Ka band down converter which converts 26.5GHzRF  to 720MHz IF. I have read the Making Mixer Measurements (Option 089), but still not sure... So here are my questions:

1. How do I find out whether I have this 089 Option. I have tried to follow the
System menu. But it does not lead to somethings like "Installed Options".

2. I'm starting out with testing/playing with a 3GHz Mixer from MiniCircuits with a 150MHz Low Pass filter at its IF port. I have its LO port connected to a
Signal Generator at 1GHz and +13dBm. So now I'm trying to sweep the RF from 1.050GHz to 1.5GHz and expect the IF output to follow the shape of the LP Filter. But nothing coming out.  

Could someone give me an example, step by step of a Mixer Test.

Thanks in advance.
