WaveForms Live Reference Manual

Despite our hopes and effort to create an innovative and low-cost T&M solution, we’ve received consistent negative feedback on the OpenScope MZ and OpenLogger regarding overall reliability that has led us to determine that it is not up to our high standards for our test and measurement products.

Unfortunately, we are unable to fix many of the issues, so we have made the difficult decision to pull both products, and related accessories from our shelves. This will allow us to ensure we can continue to deliver on the Digilent brand promise and focus our efforts on expanding our popular and core line of Test and Measurement Products.

The materials on this page will remain here as legacy sources. Any Digilent provided support for this material will be extremely limited at best. Thank you for understanding.

WaveForms Live makes it easy to control and interact with instrumentation hardware by providing a cross platform graphical user interface that combines support for an oscilloscope, logic analyzer, GPIO, power supply and more into a single application.

WaveForms live is free and open source. Try it now at WaveFormsLive.com.


WaveForms live is available as a hosted browser app at WaveFormsLive.com, as an 'offline' browser app as part of the Digilent Agent, and as a native app for Windows, Mac, Linux, Android and iOS.

The browser based version of WaveForms Live at WaveFormsLive.com is recommended as it will include the latest features and bug fixes.

WaveForms Live is open source and built on Ionic 2 and Angular2 and written in TypeScript, HTML and CSS. The source code is available on GitHub.

Add A Device

The add device drop down enables users to add new devices to WaveForms Live. Three device types are supported: Network, Simulated, and Agent.

  • A simulated device is a pure software device that is designed to provide a way to test the WaveForms Live software without additional hardware.

  • A network device is a WaveForms Live compatible devices that is available on the local network (ex. an OpenScope MZ on the local Wifi network).

  • The Digilent Agent is a service that runs in the system tray on Windows, Mac and Linux and enables browser based applications like Waveforms Live to communicate with Digilent hardware. Using the Digilent Agent to connect to a device connected to the computer via USB offers several advantages including the ability to update the device firmware and setup Wifi. The Agent must be configured using WaveForms Live to set the active device before use.
