There is a bare-bones AWG from China that is based on the Analog Devices AD9106.

It's available on Aliexpress and eBay, but does not appear to have a product name. To find it, search these sites for "AD9106".
It can be controlled over USB as a USB serial device. The Windows 10 default drivers can be an issue so it may be necessary to fall back to the STMicroelectronics Virtual COM Port driver designed for Windows 8.
The official documentation for the AWG's USB protocol is limited. It is text based with end-of-line being a carriage-return and linefeed byte pair. To upload arbitrary data to it, issue a series of "Z" commands with the appropriate parameters followed by a single "OVER" command (no parameters).
