My NI USB device will occasionally lose connection to the computer, and I have to disconnect and then reconnect it before it will work. Why does this happen, and how can I get Windows to re-detect the ...

This article explains how to determine the value of bias resistors when measuring signals using a floating source. Bias resistors are required when using the DAQ with differential or nonreferenced single-ended ...

I am recording measurements from a multifunction I/O device. Currently, Iam using the DAQ Assistant to read a number of samples and output them on a graph. This happens inside a loop to read samples continuously. ...

I want to know the error associated with the "Non-Linearity" of my DAQ device. What are the INL and DNL errors in the specifications of my DAQ device?

I am getting an error -200077 when trying to use a NI-DAQmx APIs: Error -200077 Requested value is not a supported value for this property. The property value may be invalid because it conflicts with ...

This article provides guidance on how often NI devices need to be calibrated and how to find the specific calibration interval for individual Multifunction I/O DAQ, Digital Instruments, High-Speed Digital ...

I have created a DAQmx Task that references multiple devices. I keep seeing error -89137. How can I fix this? I am programming multiple tasks or connecting multiple terminal routes in an NI-DAQmx device.However ...

I need to use hardware-timing on ports other than port 0 of my X series device. However, when I configure my task to include other ports, I receive Error -201062, pictured below. When trying to use PFI ...

I am using Analog Output channel on my DAQ device and I see random or periodic spike or glitches in my signal when reading it with a scope or an analog input channel. How do I overcome this issue?

This article outlines methods for troubleshooting and isolating the causes of measurement offset and noise in Multifunction I/O DAQ hardware.
