Dear All!,
Could anyone help to assembly a setup test. I have an IQ Quadrature Modulator (Polyphase ) with: 4 input`s (I, Ī and Q, ΞQ). Further, my RF LO(Local osc.) and RF Output (Mod. Signal). I have also, an Arbitrary Waveform Generator, which I would like to use to create my "I and Q". A RF signal Generator to my LO too.
IF I want a signal em 2,5 GHz, which will be my setting? Could you help me? If anyone want details I will share it....as well as info about my equipment... Thank you
 

Maybe you can draw the setup in your mind, so we can talk about it?
 

To fully utilize the I/Q modulator capabilities, you need a dual channel arbitrary waveform generator. Adjust the amplitudes and DC offset according to the modulator specification, that's all.
 

Yes, please, see the Pic. attached.

Could you say me some more? In that case, a 10 GHz modulated signal has been wanted. Thanks,
 

FvM I did it, and worked fine, the dual channel arbitrary waveform generator. Now, could say me how can I will set it signal to work as a pulsed RF signal?
 

In order to have a pulsed RF signal, either I or Q channel is sufficient. Generate a baseband pulse signal on either of them(I or Q), apply LO, you will observe pulsed RF at the output.
