OpenScope MZ is an open source, multi-function, electronic instrumentation device that can be controlled using a computer or mobile

device to acquire, analyze, visualize, and generate signals from circuits, sensors, and other electronic devices. OpenScope MZ makes it easy

to generate analog and digital signals using the power supply, function generator and GPIO () and measure and visualize analog and digital

signals using the oscilloscope and logic analyzer. Develop and debug circuits faster by generating stimuli and visualizing the response using

OpenScope MZ.

2/10/2018 OpenScope MZ Reference Manual [Reference.Digilentinc] The OpenScope MZ has a single channel 10 MS/s () 10-bit function generator. An R2R resistor ladder with 1% resistors is used in place of a DAC (). Due to the nature of resistor ladders, it is possible to have a missing code for steps larger than 3 mV or encounter propagation delays, most notably when switching between the values of 0x1FF and 0x200.

The host computer will need a USB 2.0 High Speed (or better) port to allow the OpenScope MZ to run at 1.
