DATAQ Instruments Application Notes and News
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
Three Easy Steps for Stand-alone Data Logging Using a DI-71x Data Logger
Data Logger > Stand Alone Configure Connect a Data Logger to the USB or Ethernet port of your PC and run the provided set up software. Configure the data logger for your specific requirements in the following ways: Enable or disable specific analog channels in any order. For enabled channels define input configuration (single-ended or Read More
Data Acquisition Tips and Techniques
Data Acquisition > Mixed Measurements A Guide To Data Acquisition Signal Input Configuration Does a thermocouple signal require isolation? Should the output of a strain gage amplifier be connected as a single-ended or differential input? Is a differential input always a better choice than a single-ended configuration? These fundamental instrumentation questions may not be easy Read More
