Hi Folks,
Long story short, none of the DDS modules I've found so far has the
ability to be sweeped or FM-modulated. This one has a signal input
terminal block "SIN" but I received a response from the manufacturer
that it connects to nowhere, it has no function:

What I need in my case is DC-100Hz of sweep or FM bandwidth. Operating
frequency under 10kHz and sweep range up to 2kHz. Of course I can whip
up an analog solution but it won't be as precise and most of all not
really programmable.
Is there anything better? Cost is not a big issue but should be somewhat
small and a display would be nice.
If you have an FPGA in your project, stick it in there. DDS is easy to
implement in an FPGA.
