Use the all-in-one USB multi-instruments to measure, visualize, analyze, record and control mixed signal circuits

With lab spaces decreasing and engineering teams becoming more distributed, companies are choosing all-in-one instruments as a supplement to traditional laboratories, creating a need for a portable test and measurement bench that can support all types of designs. USB test and measurement devices can be used in a variety of applications including testing embedded systems and maintenance work on electronic devices. In addition, data captured can be quickly downloaded directly to the computing device and easily shared with others. Users can also send measured data directly to the Cloud and build automated test labs.

Digilent Inc, A National Instruments Company, is set apart by the unique expertise in FPGA-based systems, test instrumentation, and even in software, with the powerful multi-instrument software application, WaveForms. Engineers can use Digilent test and measurement devices to decrease their design cycle time and increase their impact by always having an oscilloscope, logic analyzer, waveform generator and more within reach. Digilent Analog Discovery 2 enables engineers to continue their designs in the library, home offi­ce, or even a coffee shop without having to reserve a lab that has all the necessary equipment.

Analog Discovery 2 is a USB multi-function instrument that allows users to measure, visualize, generate, record, and control mixed-signal circuits of all kinds. The Analog Discovery 2 is small enough to fit in your pocket but powerful enough to replace a stack of lab equipment. It comes with the FREE multi-instrument software application, WaveForms. The Waveforms seamlessly connects to Analog Discovery 2 with full Windows, Mac OS X, Linux and Raspberry Pi 4 support. Driven by WaveForms software, Analog Discovery 2 can be configured to work as any one of several traditional instruments including an Oscilloscope, Waveform Generator, Power Supply, Voltmeter, Data Logger, Logic Analyzer, Pattern Generator, Static I/O, Spectrum Analyzer, Network Analyzer, Impedance Analyzer, and Protocol Analyzer.


Test MEMS Microphones with Analog Discovery 2

MEMS microphones are a new class of acoustic sensors. When building a product that includes MEMS microphones, it is important to test the microphone to ensure they work and are sealed. Digilent provides free example project to demonstrate how to use Oscilloscope, Logic Analyzer and Pattern Generator in Analog Discovery 2 to test an MEMS microphone. The testing program is written in JavaScript. Analog Discovery 2 streams live audio data from the MEMS microphone and displays it through the WaveForms oscilloscope. The data is presented as a waveform in the time domain and as an FFT. The project details and files are available at Digilent Wiki. In a situation where a custom sensor is being prototyped, you would also be able to scope the analog data itself, and compare the results of the conversions to the real waveform.

When lab spaces are not always available or convenient, the Analog Discovery 2 is a great choice as a supplement to traditional laboratories. With Analog Discovery 2, it easy for engineers and developers to acquire, visualize, store, analyze, produce and reuse analog and digital signals.

Digilent Analog Discovery 2 is also available at Digi-Key
