Data Acquisition > Software > WinDaq We’re often asked how to best measure a discrete input with an analog data acquisition system. Many of our products provide discrete (digital) input ports that can be read with WinDaq data acquisition software, but sometimes it’s better to acquire the discrete input along with the analog data through Read More

Data Acquisition > Starter Kits This final installment describes a ratiometric approach to frequency measurement used by the DI-149 and DI-155 data acquisition starter kits that resolves the problems encountered by pure analog and other digital techniques. As a recap, pure analog approaches will not allow very low frequency measurements, and although typical digital approaches Read More

Data Acquisition > Starter Kits In Frequency Measurements Part 1, I described why you might need to include frequency as part of a complete data acquisition or data logger measurement. In this part I’ll explain how a data acquisition or logger system typically makes a frequency measurement and point out the pitfalls of each approach. Read More

Data Acquisition > Starter Kits Since our newest data acquisition starter kit (DI-149) supports a frequency measurement function I thought I’d burn a few posts to talk about that feature in general terms. In this first part I’ll talk about where frequency measurements are typically encountered with examples of the specific information that can be Read More
