I've bought an evalution board with AD9959. I readed instruction how to configure it with your software. Everything's ok, but i've got some troubles with setting linear frequency modulation. I dont see any changes of signal on my spectrum analyser with or without this mode. It's written about some example setup files in your PDF (AD9959_Eval_Bd_Instructions, p. 21), but I didn't found them anywhere on CD or in internet. Please, help me with settings for software to turn on linear frequency modulation. For example I need  to set linear sweep with such parameters: Fmin = 15MHz, Fmax = 25MHz, period = 10us.
