improve the quality of the signal DAQ 6008 with labview

[anouardz]

Hello,

I’m doing an analog data acquisition with DAQ 6008 for a graphical observation and tdms recording, and I want to improve the quality of data acquisition at two digits after the decimal point, and I saw in the labview library that there are filters, calculates of the arithmetic mean, spline … but I’m a beginner in labview and I don’t know what to use to improve the quality of the signal, if you can give me some examples it will be better.

You have to be specific. What is wrong with the signal? Attach an image of what you are acquiring. It may have nothing to do with LabVIEW but related to signal wiring and a noisy environment. You need to provide details on the source of your signal, etc.

The USB-6008  is a low performance device so there will be limits to how much improvement you can make.

Two digits after the decimal point is meaningless. How many digits do you have before the decimal point? The total number of significant digits is more useful.  

The system noise limits you to about 3 to 3 1/2 significant digits. Absolute accuracy is about 2 1/2 digits.
