Are you using the latest driver? The one I use has a function called ag33xxx - Waveform Parameters that allows you to individually change frequency, amplitude, or offset. After setting the amplitude with it, you can then use the function again in a loop to adjust the frequency while keeping the amplitude constant. The driver can be downloaded from NI <A href="http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/0027109f3d6e32dd86256d6d0068a5bd?OpenDocument">here</A>.
