What is a DAQ?
Data Acquisition (DAQ) refers to the method of taking analog sensor measurements and transforming them into a digital signal that a computer and its software can understand and process. Simply put, a DAQ acquires a measurement signal and records it for later analysis (post-process).
There are a variety of sensors that could be measured (accelerometers, microphones, strain gauge, laser vibrometers, temperature, etc). Each of them may require their own conditioning (power requirements). Having a DAQ system that provides a wide range of conditioning options means you don’t need separate DAQ hardware or extra external hardware.
What is an Analyzer?
The next step after data acquisition is analyzing the data you’ve collected. Or, in some cases you may want to perform analysis in real-time during the data acquisition. In this case you can use an analyzer.
The analyzer (and subsequent analysis) might be as simple as looking at the time signal waveform to look for a variety of statistical properties (peak, average, mean etc). Other analysis might include looking at frequency content and responses such as FFT, FRF or octave bands for acoustics. If you need to look at the dynamic behavior of a structure or system you could perform modal analysis.
