Data Acquisition (DAQ)
Data acquisition (DAQ) is the measurement, recording, analyzing, and presentation of real world phenomena. It includes electrical measurements such as voltage, current, power as well as measurements through sensors and transducers including temperature, pressure, strain, vibration, and more. Selecting the ideal data acquisition system or solution depends on your application. Typical factors include sample rates, channel scalability, signal conditioning, sensor types, analysis capability, mobility, and environmental conditions.

Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.
How-tos
Using the DL350 Memory Recorder Mode Easy Setup, combined with a 16-channel thermocouple input, it's easy to record hours, days, or weeks of data with a few simple settings.
CAN Bus communication is widely used in the transportation industry where reliable transmission of data is paramount. Monitoring and recording these communications can be easier when using the proper instruments. In this video, a Yokogawa Test&Measurement Applications Engineer demonstrates how to setup the DL950 ScopeCorder to read the temperature of a motor drive alongside its voltage and current output.
The multi-unit synchronization option for the Yokogawa Test&Measurement DL950 ScopeCorder lets you time synchronize up to five DL950 ScopeCorders, for up to 160 channels of voltage, current, temperature, strain measurements, and more. This video walks you through how to set up and connect the multiple DL950 ScopeCorders, take measurements, and pull the data from all of the instruments for analysis with the IS8000 Integrated Test and Measurement Software Platform.
