MATLAB Support for Data Acquisition Starter Kits

We are happy to announce the availability of MATLAB scripts for our data acquisition starter kits that specifically support our low-cost starter kit models DI-145, DI-149, DI-155, and DI-245. MATLAB is an analytical tool that is especially popular at the university level, and anywhere signal analysis is performed. The scripts we’ve released allow data to be Read More

Save Select Channels as a New WinDaq File

Data Acquisition > Software > WinDaq Perhaps you’re using WinDaq data acquisition software to record a file containing 10 or 20 channels of data. Now suppose you’re sending that file to a colleague, who is really only interested in two of those channels. Your colleague now has to dig through the file, looking for the Read More

Die Cushion Qualification

Data Acquisition > Mixed Measurements DATAQ Instruments was recently mentioned in Evaluation Engineering magazine‘s special report on data acquisition systems. The feature focused on applications in machine condition monitoring, which is an area that is very popular for users of our equipment. So, we thought we’d publish an overview of it here for our readers. The specific Read More

How To Calculate Common Mode Rejection Ratio

Data Acquisition > Voltage > DI-245 Common Mode Rejection Ratio Defined Editor’s update: All information in this application note applies equally to model DI-808 data logger with a built-in Web server. Common mode rejection ratio doesn’t seem at all common. In fact, it sounds rather fancy and complicated. But it’s actually a simple concept. Recall Read More

Acquire Data in Minutes

Data Acquisition > Software > WinDaq WinDaq data acquisition software allows you to acquire data in minutes! So you’ve chosen a DATAQ Instruments data acquisition system or data logger, you’ve connected the instruments to your PC, and you’ve successful installed the software. Now what? How do you record data? WinDaq data acquisition software allows you Read More

Save a Segment of Data as a Second, Smaller File

Data Acquisition > Software > WinDaq   The WinDaq Waveform Browser allows you to select a segment of data, and save it as a second, smaller file. Suppose you have a very large data file, recorded over several days, or even weeks. Now suppose that that file contains a significant event that transpired in a matter of Read More

FFT (Fast Fourier Transform) Waveform Analysis

Data Acquisition > Software > WinDaq To calculate an FFT (Fast Fourier Transform), just listen. The human ear automatically and involuntarily performs a calculation that takes the intellect years of mathematical education to accomplish. The ear formulates a transform by converting sound—the waves of pressure traveling over time and through the atmosphere—into a spectrum, a Read More

Data Acquisition in Microsoft Excel—How to Import Recorded Data

Data Acquisition > Software > WinDaq > WinDaq/XL In our experience, Microsoft Excel is the most popular application for waveform analysis. Our customers ask about porting waveform data to Excel more so than all other applications combined. In response, DATAQ Instruments’ developed WinDaq/XL to allow users of WinDaq software (both recording and playback software) to Read More

Medical Research using WinDaq

Data Acquisition > Software > WinDaq Data acquisition hardware and software offer unique waveform storage and analysis features particularly useful for medical research applications. WinDaq in tandem with Advanced CODAS analysis software has been applied in a wide range of medical research (MR) applications; a market segment notoriously demanding in both price and performance. An Read More

Electromyogram (EMG) Waveform Analysis Software with Advanced CODAS

Data Acquisition > Software > WinDaq > Advanced CODAS With the advent of data acquisition systems, acquiring data from real-world applications has never been easier, more accurate, or more reliable. Once acquired, the data file can be examined and analyzed just as easily. In some applications, the data requires little or no analysis. Simply reviewing Read More
