Hi Dominic, Thank you very much for responds.
I had connected to P9 on my hackrf board before. But as expected a I see only a single signal. I cannot justify if that is the I component or the Q component. However I am wanting to see both components ( two signals) for my analysis. How can I do this tapping the base band from P9 as I did? What are your suggestions for the levels on my oscilloscope? Thank you very much Ernest. Sent from my BlackBerry 10 smartphone.

The P9 header on the board allows you to access the baseband [1]. You'll need to make sure that the levels are appropriate for your scope, but I would imagine that they should be fine. You can see the hardware design files in the HackRF repository[2], and you should consult those for the pin connections.
