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 …

In this post, the hardware design for the Eclypse Z7 to perform wireless communication is discussed. The initial considerations behind the circuit design and PCB design have discussed in this …
Thermocouples are a popular way to measure temperature due to their low cost, ease-of-use, and wide measurement range. This article explains the difficulties in making accurate thermocouple measurements, how the …
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 …
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 …
Using Additional Software to View Date Remotely Now that we’ve created a working distributed data collection and display system (see parts 1 through 4), let’s briefly explore other software packages available …
Software Defined Radio (SDR) is a radio communication system that performs many traditional radio functions in software instead of dedicated hardware circuits. Tasks such as filtering, modulation, demodulation, signal generation, …
Most students do not struggle with equations. They struggle with understanding what those equations actually do. In many learning environments, students define a system, run a process, and then interpret …
If you’re choosing between an FPGA and a SoC, the real question is not which one is “better.” It’s which one fits the job in front of you. Here is …
You open a Verilog example, launch Vivado for the first time, or start reading for a digital design course, and one term keeps showing up: RTL. It usually appears as …
