Last month, I described a simple stateless web application using Python and Plotly’s Dash module. It created a dashboard allowing users to select waveform channels, update rate, and the number …
Consider Dash if you’ve ever wanted to create a web browser application using Python. With Dash, you don’t need to be good at using JavaScript, great at Cascading Style Sheets …
Introducing JupyterLab JupyterLab is a relatively new tool. It is an open-source development environment (IDE) for working with Jupyter notebooks. Notebooks are primarily used to combine program code, code results, …
Using a data acquisition device (DAQ) can be challenging. Often, connecting to a single channel produces a suitable measurement. Yet, DAQs seldom have a single channel; trouble usually happens when …
Digilent WebDAQ devices, such as the 316, 504, and 904, are standalone data acquisition devices that offer a user-friendly web server interface. This interface, accessible through your preferred Internet browser …
A software-defined radio (SDR) is not a radio in the traditional sense. Instead of fixed analog components with limited range and ability, an SDR is programmable and highly flexible. Referred …
In twenty years, will we own an automobile, or will fleets of autonomous vehicles roam the streets waiting to be hailed? In the United States, over 30,000 people die on …
This blog post discusses the concept of lock-in amplifiers and will introduce you to a newly added feature of WaveForms. The new Lock-In Amplifier feature is supported across all of …
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 …
How Do You Measure an IEPE Accelerometer? The Basics of IEPE Sensors Matching IEPE (Integrated Electronics Piezo-Electric) sensors to an instrument can be quite easy if you know a few …
What Do Data Acquisition Specifications Actually Mean? I got my first taste of data acquisition working in a student lab at NASA Glenn Research Center. I was working on a …
Signal processing starts with data. Whether you are working with sensors, audio signals, or transient events, the ability to capture clean, high-resolution data directly affects what you can learn from …
Most parts of engineering work are fairly flexible at this point. You can review schematics from anywhere, push firmware changes without being tied to a specific location, and work through …
Howdy from Ft. Worth, Texas, where another NI Connect came to a fabulous end last week. Digilent was proud to share new tech, provide live demonstrations of our fan favorites, and generally …
Outfitting a lab is rarely about finding a single perfect instrument. In most cases, the goal is to choose tools that are flexible, reliable, and capable of supporting a range …
