USB D/A interface for SATSAGEN

A USB D/A interface for SATSAGEN to output analog sweep ramp (0-10Vpp)

This USB interface is a D / A converter compatible with SATSAGEN application, in order to drive external systems, like a SNA that accept horizontal input with ~ 10Vpp. With this interface SATSAGEN can be used as a sweep generator.
