A Data Acquisition System is a general measurement system which can measure temperature and some electrical parameters such as voltage, current, resistance and more. Here, Keysight´s Daniel uses the NEW DAQ970A to demonstrate three simple steps to make temperature measurements with a DAQ.
There are three key steps for data acquisition systems:
Step 1: Connect and configure your hardware
Step 2: Setup and run tests
Step 3: Export and analyse data
The purpose of any data acquisition system is to gather useful measurement data for characterisation, monitoring, or control.
When performing product characterisation, you will likely need to:
• Measure multiple inputs, such as ten temperature points
• Measure multiple types of inputs, (e.g. voltage, current, temperature)
• Optimise test accuracy and measurement speed
When monitoring a product or a process, you will likely need to:
• Take readings periodically, for example, every minute for 36 hours
• Pre-process or compute the data while recording them into a file for post processing analysis
• Trigger external alarm lights, sirens or control systems to take corrective actions
When controlling your test process is required, you will need to:
• Provide analog output signals to control actuators, motors
• Provide digital output signals to control devices
• Route signals using a switching card to power or connect test signals to a device
