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 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 want to test the analog output of my DAQ device using the NI MAX Test Panels, however, I can't change the frequency of my analog output signal. Is it possible to modify it to get different frequencies? ...

I am using the Pulse Measurement Counter Input tasks in DAQmx with my DAQ device and I am getting the following error at DAQmx Create Channel VI : Error -200431 occurred at DAQmx Create Channel (CI-Pulse ...

You may need to control a stepper motor drive (step or direction) using the digital outputs of your USB DAQ. This article will help you control the motor for some simple moves in LabVIEW.

This tutorial provides step–by-step instructions for setting up your USB R Series device, adding it to a project, and creating an analog input acquisition using a DMA FIFO. Requirements Software LabVIEW ...

Current cannot be measured directly using a voltage analog input device. However, if a known resistance (shunt resistor) is placed in series with the load and the voltage across it is measured, the current ...

In the Datasheet for my product, I see a section titled Input Coupling, and it is specifies AC, DC, or "AC or DC."What are do each of these input coupling types mean? Does my module support DC voltage? ...

I have a NI Multifunction I/O module with some Analog Output (AO) lines. I need to control an instrument using current. What is the current range the AO lines on my card?
