Analog Discovery Pro 3000 Serie: ADP3250

ADP 3450 and ADP3250, in the line of Analog Discovery Pro devices, offers 4 channels (ADP3450)/2 channels (ADP3250) analog input with 14-bit resolution at up to 0.5 GS/s. Additionally, to meet the needs of an increasingly digital world, 16 dedicated digital channels make the ADP3450 a true mixed signal oscilloscope. With the included digital power supply, digital outputs, two channel arbitrary waveform generator, and two dedicated external triggers Analog Discovery Pro comes with 12 instruments ready to analyze mixed signal systems through our free software, WaveForms.

Test your systems in Linux environment

Analog Discovery Pro introduces Linux Mode. Linux Mode provides an on-device terminal-based operating system that, when combined with WaveForms SDK, is a flexible starting point for all kinds of custom tests and applications. Running embedded on the device itself or via WaveForms, engineers and measurement enthusiasts alike can take advantage of data streaming via  ethernet, and the on-device storage to capture buffers of millions of samples.

Advanced Trigger Modes

Analog Discovery Pro features a variety of advanced triggering options. Instruments within WaveForms can be cross-triggered for example, activating an oscilloscope capture based on a received and decoded digital protocol. And external signals can trigger events using the two dedicated external trigger inputs on the back of the device. 
WaveForms provides these features configurable in the instruments themselves, or for more control or automation in one of the available scripting interfaces.

WaveForms Software Applications

WaveForms is the free software application for the ADP3450 and ADP3250 and enables use of the available analog and digital instruments. The software has been refined by customer feedback for over 10 years and features a computer and laptop friendly user interface that has the feel of traditional benchtop software. The device communicates with WaveForms via a USB or ethernet connection to your computer, allowing users to capture, record, analyze, and generate mixed signal and mixed domain waveforms. WaveForms can be downloaded and installed in under 60 seconds and can be tested without hardware using its demo mode feature. In addition to the use of instruments in the application, the WaveForms application has a script editor tool, which allows custom scripting of the instrument in JavaScript. WaveForms is designed to be run on a laptop or desktop computer and is Mac, Windows, and Linux compatible.  WaveForms SDK is a set of software libraries and examples that can be used to develop custom applications that can control Digilent Test and Measurement devices. Supported languages include C, C++, C#, Visual Basic, and Python. Third-party toolkits are available for LabVIEW and MATLAB. 
Instructions for using WaveForms with LabVIEW are available through our guide Getting Started with LabVIEW and a Test and Measurement Device. More information about WaveForms SDK can be found through the WaveForms SDK Resource Center.
