Employing direct digital synthesis (DDS) technology, the Siglent 5-MHz SDG1005 and 50-MHz SDG1050 function / arbitrary waveform generators offer dual, independent channels with adjustable relative phase and are available for $399 and $599, respectively. In addition to sine waves, they also provide square, pulse, ramp, and arbitrary waveforms as well as white noise.
Along with 125-Msample/s sample rate, 14-bit resolution, and 16-kpoint waveform record length, the units also offer built-in AM, FM, PM, PWM, and FSK modulation, without ran external modulation source. Both units can also function as a 200-MHz frequency counter, and a USB Device/Host interface allows storage of waveforms and setups. (SDG1005, $399; SDG1050 $599 available now from Saelig.)
