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.
Components
- Microcontroller board like Arduino Nano
- Step-up module 5V to 15V
- LM358 or equivalent
- 1uF capacitor
- 1K, 4K7, 33K and 47K resistors
