- name label
Label of a front panel object used to name the object and distinguish it from other objects. The label also appears on the block diagram terminal, local variables, and property nodes that are part of the object. See also Caption Label.
- NaN
"Not A Number." Digital display value for a floating-point representation of not a number, typically the result of an undefined operation, such as division by zero.
- network
A group of computers (and/or devices) that can communicate with each other.
- network-published shared variables
A Shared Variable that has been configured to be accessible to other computers on the network. See also: Shared Variable, NI-PSP.
- NI Example Finder
A LabVIEW utility for quickly finding LabVIEW examples.
- NI-DAQ
Driver software for National Instruments DAQ boards and SCXI modules. This software acts as an interface between LabVIEW and the devices.
- NI-DAQmx
The National Instruments data acquisition driver and application programming interface.
- NI-DAQmx Task
An NI-DAQmx abstraction, containing a group of physical channels, along with timing and triggering information. Nearly all NI-DAQmx function calls operate on NI-DAQmx Tasks.
- NI-MAX
National Instruments Measurement & Automation Explorer. A configuration utility that interacts with NI-DAQ, allowing you to configure your hardware, set up virtual channels, and test your I/O from the desktop.
- NI-PSP
National Instruments Publish and Subscribe Protocol. A proprietary networking technology that provides fast and reliable data transmission for large and small applications. NI-PSP is used by network-published shared variables to communicate between VIs, remote computers, and hardware. See also Shared Variable.
- nodes
Execution elements of a block diagram consisting of functions, structures, and subVIs.
- nondisplayable characters
ASCII characters that cannot be displayed, such as new line, tab, and so on.
- Not-a-Path
A predefined value for the path control that means the path is invalid.
- Not-a-Refnum
A predefined value that means the refnum is invalid.
- notifier
A LabVIEW messaging construct that is generally used to publish non-buffered data by one or more producers to one or more consumers. The Notifier Operations Functions are used to create and use of Notifiers.
- notify event
An event which cannot be filtered. See also: Event Structure, Filter Event.
- numeric controls and indicators
Front panel objects used to manipulate and display or input and output numeric data.
- numeric representation
The type (signed integer, unsigned integer, floating point, complex number) and size (8 bit, 16 bit, 32 bit, 64 bit, etc.).
- NRSE
Nonreferenced single-ended.
- NRSE Measurement
All measurements are made with respect to a common reference. This reference voltage can vary with respect to ground.
- nyquist frequency
One-half the sampling frequency. If the signal contains any frequencies above the Nyquist frequency, the resulting sampled signal will be aliased or distorted.
