Programmed in Arduino.
The Teensy development board is fully compatible with the Arduino programming language and environment. Take advantage of the simplicity of coding and the endless resources shared by the community for programming your scientific device. The Teensy drives the AD9851 sweep and reads the AD8302 gain and phase through its ADC (13-bit effective resolution over 3.3 V). Firmware is uploaded with the Arduino IDE and Teensyduino.
