This document is part of the Getting Started with NI-DAQmx Series. A Pulse Width Modulation (PWM) Signal is a technique for generating digital pulses to control an analog circuit. A PWM signal consists ...

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 want to output a chirp signal through my DAQ device in LabVIEW. Is there a way I can easily create a Chirp Signal in LabVIEW? Are there any considerations that need to be taken into account?

I would like to accurately measure voltages between 14 V and 18 V. Is it possible to use a normal data acquisition +/-10V module to do this?

I have multiple NI data acquisition (DAQ) devices. When I acquire data (DAQmx Read (VI) multiple channels) and then merge them in to one TDMS file by usingTDMS Write Function, the resulting file volume ...

I want to control a stepper motor drive (step/direction) using the digital output on my USB DAQ and I have connected all the necessary wiring, so how do I control the motor for some simple moves in LabVIEW? ...

I am using multifunction I/O DAQ device. When I measure sine wave whose frequency is 500 kHz and the peak is 1 V, I found that the measured value has lower peak though I could measure 1 V level signal ...

You depend on measurements to make key decisions and discoveries. NI offers a wide range of data acquisition products, including the low-cost DAQ family for basic applications such as simple data logging, ...

I know that bias resistors should be used when measuring floating sources with differential input or nonreferenced single-ended (NRSE) input systems. However, I am not sure what resistance values I should ...

How do I measure current with an analog voltage input? Do I need a shunt resistor in my current measurement circuit?

How do I troubleshoot offset, incorrect, or noisy readings in my DAQ system? My DAQ device is measuring incorrect values. How do I troubleshoot this issue?

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 ...

I am using a NI X-series DAQ hardware, why do I get high output in the DIO lines during the computer powering up state or after computer is shut down. Can this be changed?

My DAQ device uses scatter-gather DMA to get data from the board to my computer, what does this mean?

While reading the specifications of my DAQ device, I found a terminology called Absolute Accuracy at Full Scale. What is the meaning of Absolute Accuracy at Full Scale and how can I calculate it?

I am deploying an application that uses a USB DAQ device and everything works fine. However, every time I connect the USB DAQ device, the NI Device Monitor popup window shows up with a Device Detected ...

I built a LabVIEWapplication and the behavior is not the same as in the development environment. The executable does not show any error, butit does not work correctly. I built an executable in LabVIEW ...

I have one or more channels on my DAQ device not connected to any signal or sensor or the device is disconnected from the computer. Why are all of thechannels reading the same value? Why are my channels/signals ...

I have old DAQ hardware or hardware that uses DAQmx that I am not sure is supported in my version of LabVIEW. How do I determine if my version of LabVIEW or DAQmx is compatible with my hardware and operating ...

I have a PCIe card, and it shows up in NI MAX and in Windows Device Manager, but it doesn't show up in NI Device Monitor. I have a USB RIO, and it shows up in NI MAX, but it doesn't show up in NI Device ...

I have seen products that were in a "Mature" state in their life cycle, but the product page of my hardware does not say anything about its life cycle. Can I safely assume it is in the Active stage of ...

In the DAQ device specification sheet, there is about a type of ADC(Analog-to-Digital Converters). What types of ADC are used in National Instruments DAQ Devices, such as Multifunction I/O DAQ, DSA or ...
