If I set Channel 1 of U2300A/U2500A with voltage range of 5V, I get a reading of 4.99968 when nothing is connected to the DAQ.
If you don't have anything connected to the DAQ and you do an acquisition out of it, the result…

Why do we see unused port in U2300A/U2500A with similar waveform and frequency but with lower amplitude to its adjacent or close by used port?
It is recommended to ground all the AI connection that is not being used. If you have multiples of AI channels to be used, one good way is to have…

FAQ 2010-08-09

What is the clock rate for Digital Inputs(DI) and Digital Outputs(DO) of U23xxA and U25xxA USB Data Acquisition?
The DAQ DIO is not meant to measure DI with clock rate precision or to control frequency of digital output

FAQ 2010-07-18

Is number of bits the only factor to look at if I'm measuring at very low voltage say 5mVpp?
No it is not. Often times, you will have to look at the Gain Error and Offset Error as well as...

What is the main difference between the digital output (DO) of the U2100A, U2600A, U2300A and U2500A?
The DO port of U2100A and U2600A requires external power supply to be pumped into the port...

FAQ 2009-10-20

How do I know what is the best sampling rate to use for my measurement?
Typically if you follow Nyquist theory, your sampling rate should be 2x the highest frequency of the incoming signal that you are measuring. However, we recommend that you use 5x...

How much of data points from my data acquired can I save into one file?
What we observed is that if you log your file into *.csv file, the most no. of points you will be capturing is 65536 points. However, if you are saving into *.txt file, it will depend on the type of...

FAQ 2009-09-29

Why do I receive an error message below ?
Generally, if you are sampling at 60kSa/s and above, you should use high sampling mode to acquire data. This is just a rough guideline. If you encountered this message even when....
