Title: Diode Ring Modulator - ADALM2000 
By: Don Kuenz

Abstract: 
  The ADALM2000 advanced active learning
  module is an affordable, USB-powered, software-
  defined instrument for students, educators, and
  hobbyists. It's Diode Ring Modulator tutorial
  leaves a lot to be desired. This article seeks
  to rectify Analog Devices's tutorial with a
  working example.
