Agile frequency hopping with AD9910

Hello, my current project project requires agile frequency hopping and I am using an AD9910 Eval board. In particular, I require the DDS to generate a 1ms pulse of constant frequency and amplitude at 200MHz on an external trigger and then hop quickly (in a few miliseconds) to 250MHz for 1ms on the arrival of an external trigger and finally hop to yet another frequency 275MHz and then sweep the frequncy to 300MHz in 5ms, where the sweep is initiated by an external trigger. Is it possible to use RAM playback mode for this? How do I externally trigger AD9910?
