Problem: I have an executable containing the LabVIEW Application Builder. Which LabVIEW Run-Time Engine do I need to own it?
The LabVIEW Run-Time Engine have to be installed on any system in which you plan to own executables or shared libraries created with the LabVIEW Application Builder. The major version on the LabVIEW Run-Time Engine must match the key version with the LabVIEW Development Environment that has been used to produce the executable. To find the most important version in the LabVIEW Run-Time Engine see KnowledgeBase 6AA9E2LF: How to Determine the Installed Versions on the LabVIEW Run-Time Engine.
Multiple versions with the LabVIEW Run-Time Engine can be placed on the same computer as long as the main version number and the bitness is unique. On a 64-bit system you are able to install 32-bit and 64-bit versions on the LabVIEW Run-Time Engine with the identical version number side-by-side. If you install an SP1 version on the LabVIEW Run-Time Engine with a system that already contains the non-SP1 version installed, the SP1 version will replace the non-SP1 version.

Switch-mode audio power amplifiers have become increasingly popular because of their smaller size, lower weight, and improved efficiency. Their advantages are obvious in low power battery operated personal apple ipods and notebooks. However they are also progressively displacing classical linear designs in mainstream applications like home entertainment systems, automotive sound systems, and professional installations where premium quality audio is essential. Measuring the performance of switch-mode amplifiers presents new and unique challenges. They inherently generate ultra-sonic artifacts and spurious signals with slew rates that may provoke non-linear behavior in the input stages of excellent audio make sure measurement equipment. Absolutely worthless and inaccurate results might occur unless effective measures are taken up prevent this non-linear behavior. Written by Bruce Hofer.

Discusses writing and reading good audio specifications. Guidelines are given, then key specifications for 2 classes of audio device are examined for correct expression and form, with instances of real-world specs to compare.
Audio analyzers are optimized to produce high quality measurements up through their maximum specified bandwidths. The presence of significant energy above these bandwidths may have a profound effect around the audio measurements and maybe induce errors. This white paper provides valuable home elevators avoiding the potential of errors when testing digital to analog converters and also other audio devices that includes significant energy over the audio band. Written by Bruce Hofer
Switch-mode audio power amplifiers are getting to be increasingly popular because of the smaller size, lower weight, and improved efficiency. Their advantages are obvious in low power battery operated personal ipods and notebook computers. However they are also progressively displacing currently established linear designs in mainstream applications including home entertainment systems, automotive sound systems, and professional installations where excellent audio is significant. Measuring the performance of switch-mode amplifiers presents result-oriented and unique challenges. They inherently generate ultra-sonic artifacts and spurious signals with slew rates that will provoke non-linear behavior inside the input stages of top quality audio make sure measurement equipment. Absolutely worthless and inaccurate results might occur unless effective measures are delivered to prevent this non-linear behavior. Written by Bruce Hofer.
This reference handbook is usually a practical, hands-on guide for workers in all of the phases with the audio field. It covers basic tools and techniques, common environments for audio testing, putting on these techniques to common audio devices, the conventional ranges of performance can be expected in different devices, along with a glossary of terms and key specifications utilized in audio measurement. 178 pages Written by Bob Metzler.

Note: All APx instruments use a similar APx500 measurement software, however, some features or downloads are certainly not supported on every model. For example, the APx Blu-ray Disc Sample Project requires an APx585 with HDMI. Therefore, don't assume all download displayed here will continue to work with every kind of APx. Requirements are indicated on each download.
Resources for API developers. Includes and C templates and example code, C examples, LabVIEW examples, plus the APx Wavereader dll. Documentation includes Intro to Programming the APx500 API as well as the APx API Browser. The APx LabVIEW driver is really a separate download.
This APx API wrapper dll permits you to access the complete APx API when you use Agilent VEE and The Mathworks MATLAB. A discussion and instructions are usually in the kb article Using APx with VEE. This download is merely necessary for APx500 v2.4. APx500 v2.5 and then already include it.

The APx LabVIEW Driver is really a collection of Virtual Instruments VIs which provide LabVIEW users with most from the functionality easily obtainable in the APx500 Application Programming Interface API using dangerous, LabVIEW - typical subVIs. With the driving force, you will soon and efficiently develop APx applications with clean, concise LabVIEW code. Please note the LabVIEW Driver is specific per release of APx500. Requires LabVIEW 2010 or older.
The LabVIEW DAQ Driver for APx515 communicates directly with APx515 hardware and won't utilize the APx500 measurement software or API. Its functionality resembles NI DAQmx, making it possible to upgrade an active test system that utilizes DAQmx to operate the APx515 with reduced effort. Requires LabVIEW 2012 or later, and VIPM 2014 or later for installation.
If you might be looking for any LabVIEW driver that communicates using the APx500 software throughout the API, then download the APx Driver instead.

The WaveReader DLL provides functions that might be called from an outside program, allow transfer of acquisition data from an APx analyzer fot it program in near real-time. compliant language like C, , or LabVIEW might make use of it.
APx Digital Serial I/O configuration files for A/D, D/A, and sample rate converters. Simplifies configuring the analyzer. Requires: 1 APx500 measurement software and a couple an APx instrument while using DSIO option installed.
APx with HDMI supports multiple EDID configurations. files are pre-configured many different audio formats including encoded audio including DTS. Requires APx585 with HDMI hardware. Please consult APx User Manual to find out more.
The APx Bluetooth option will be the best solution on the planet for testing audio over Bluetooth wireless technology. No other analyzer combines integrated Bluetooth controls with APx s finest in class speed, ease-of-use, and satisfaction.
This application note provides information on the best way to install, configure, and make use of Point Grey imaging cameras with NI-MAX and LabVIEW.
National Instruments Measurement and Automation explorer NI-MAX is really a viewer which allows users to configure cameras and stream images. This 32-bit application is typically accustomed to verify camera functionality.
National Instruments LabVIEW is often a graphical programming language useful for data acquisition and instrument control in a variety of platforms including Windows and Linux. For more information about programming in LabVIEW, see Introduction to NI LabView.
This document provides examples using NI-MAX v5.6. For more information, go to National Instruments website.
Before you utilize your Point Grey camera, we recommend that you will be aware on the following resources available on the Point Grey Downloads page:
Getting Started Manual for your camera provides info on installing components and software needed running the camera.
Technical Reference to the camera provides information for the camera s specifications, features and operations, together with imaging and acquisition controls.
Firmware updates make certain you are while using the most up-to-date firmware for that camera to adopt advantage of improvements and fixes.
The steps for installing and putting together depend which interface you guessed it-your camera uses.
The following sections provide more detail.
NI-MAX is packaged in the installing LabVIEW. It is intended for download on the National Instruments website. Alternatively, standalone NI-MAX software could be purchased separately here.
Follow set up . instructions.
Connect the camera to your PC. For information, understand the camera s Getting Started Manual.
For USB2 cameras, the Direct Show filter given Point Grey s FlyCapture2 SDK is needed.
