Implementing burst in AD9959

Hi all,

 

I have an application in which I would like to create a burst type of RF waveform, i.e., to output a defined number of cycles of sinusoidal waveform, the output then being idle for a fixed period of time before the new burst occurs.

I have easily implemented this initially with the AD5930, which has pre-programmed burst profiles. However, since I need multiple outputs, I am planning on moving to the AD9959.

 

Which is the most effective way of implementing this in the AD9959? I could potentially switch off the output DAC using the Power_down input, but I suspect that would not be fast enough.

 

Any suggestions are welcome.

Thanks.

 

Pablo
