TechTip: Measuring 4-20 mA Current with MCC DAQ
The 4-20 mA current loop interface came about because of the need to transmit information over long distances. System designers found that instead of a changing a voltage signal [that …

The Analog-to-Digital Converter (ADC) is today’s go-to device for changing an analog signal into a digital binary value. The ADC takes a snapshot in time that approximates the actual value …
At some point during a FPGA engineers’ career, they will be faced with a difficult bug in their VHDL or Verilog code and they’ll ask themselves: “Why are we stuck …
What is jitter? Jitter is the variance in where exactly a clock falls. You might expect that a 100 MHz clock has edges that occur exactly every 10 ns. However, …
Imagine you have just a few measurements left before you can hand over your latest project to your sales team so that they can present it to potential customers. But …
So what is it? The Digilent Test & Measurement Toolbox allows users to acquire and analyze data in MATLAB using Digilent’s test and measurment devices. Featuring analog data streaming, digital …
WaveForms. It’s the software suite that controls all of Digilent’s Test and Measurement devices including the popular Analog Discovery 2, the Analog Discovery Pro series boards, and the Digital Discovery. …
So I’ve been using the Analog Discovery Pro (ADP3450/ADP3250) and the Analog Discovery 2 for some time now. But one of the things I had to keep on my bench here …
COILS COILS COILS If you’re like me, you’ll have many wireless charging coils around your lab for various standards. They likely entered your lab well-dressed; adorned in well-labelled packaging, …
A classic interaction between a new FPGA user and an embattled older engineer (whether on our Forums or elsewhere) goes as follows: New engineer: My design doesn’t work, could you …
Acquiring and Measuring FM Radio Frequencies From Your Desktop Overview Using Waveforms’ Oscilloscope or Spectrum Analyzer instruments to acquire the typical FM radio frequencies is just one of the capabilities …
In this last installment of our four-part blog series about creating a smart lamp, we will bring everything together. The HAL for the WaveForms SDK we developed in the Part …
Building a Raspberry Pi-Based DAQ System for an SAE Baja Challenge Car The SAE Baja Challenge pushes engineering students far beyond the classroom. Teams are tasked with designing, building, and racing a …
The idea of “remote lab access” comes up a lot, but it can still feel a little abstract in practice. After dealing with the usual back-and-forth around lab access, the …
I’m not an engineer. But this will be my third time attending the ASEE Annual Conference with Digilent, and each year I leave feeling the same way: inspired. My background …
A large U.S. university with over 1,400 undergraduate electrical engineering students has developed a scalable approach to delivering hands-on lab experiences – both on campus and fully online. Serving a …
