For more information regarding a DAQ, please visit this [https://www.ni.com/en/shop/data-acquisition.html?srsltid=AfmBOop-ShC6qXu4ureq48jENtLwW7mANszhvf_x35Bpx6UD8beugJyp link].

In our lab, we are using a DAQ NI USB-6259:

[[File:Daq.jpg|300px|Picture of our DAQ, model NI USB-6259]]

'''Specifications'''
Detailed specifications can be found on the website of [https://www.ni.com/docs/en-US/bundle/pci-pcie-pxi-pxie-usb-6259-specs/page/specs.html?srsltid=AfmBOoq6huevEadUGbvg0VDbnbNFntNGujrl4xMiuFrHO2soOgXV2_Wf National Instruments]
Specific specs:
Multichannel maximum: 1.00 MS/s. This rate is shared among all input channels.

'''Ghosting'''
When reading multiple signals simultaneously, it is possible that the signal of channel X will be partially visible in the signal recorded by channel Y due to what is called ghosting. Please find more information about ghosting [https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000YHy6CAG&l=pt-BR here].

'''An example of a python script to read out channels''' Note that in the example below, we use shorts in between the three main signals to read in order to reduce ghosting. The shorts need to be read out to be effective. <syntaxhighlight lang="python" line="1" start="1">
