@ScottSeidman are you OK with them having to use something that uses digital controls instead of analog?
if so, you could use one of the lower-end ADI DDS chips with a microcontroller driving it around

Connectors ...
@RussellMcMahon @SamGibson @VoltageSpike wanted to check with you about a question on our site and whether you would want it (and whether it's a reasonable question to begin with). mattermodeling.stackexchange.com/q/8484/7
