is it possible to set frequency in giga hertz using simulink

[ashokone]

hi
i am new to simulink-as per my application i need giga hertz frequency
to generate carrier signal.

how to set frequency to giga hertz either for sine r cosine or any waveform.

while i am using blocks in the simulnk,i am able to generate only 20hz.. not more than that..

plz help me how to generate interms of giga hertz.. frequency

is there any other method for this.
thnksin advance

You are obviously doing a mistake. To have a frequency of 1 GHz, you should sample at greater than 2 GHz, some thing like 3 GHz. Can your processor handle that?

plz how shell i rectify the problem for that..i need to generate carrier frequency in terms of giga hertz..using simulink in matlab..

scale down to reasonable frequency
