I am trying to use the provided GUI with the eval board (AD9914) to generate a saw-tooth ramp where I would like to have control of ramp duration as well as no signal period between each ramp. In other words, I don't want to generate a saw-tooth such that the next ramp immediately starts as soon as the first one ends; rather, I'd like to set a sleep time (or single frequency time) between consecutive ramps. Any suggestions what's the easiest way to do this?
I could only think of using the No Dwell High feature of the parts to make the ramp stay on a single frequency after each ramp. But with this, the frequency will stay on the programmed Sweep Frequency 0 and a Ramp Up command should be issued again to make the ramp go up.
