Better Dynamic Specifications – The analog input path on S Series

devices is tuned for both accurate DC and dynamic measurements, while

multiplexed data acquisition devices suffer from settling time and

distortion error created by switching the input channel.

Many Input Ranges – You can configure each analog input channel

to use one of four voltage ranges, from ±1 to ±10 V. By selecting the

input range most appropriate for your signal, you maximize the available

16 bits of resolution.

Signal Conditioning – With the release of NI-DAQmx 7.4, all S Series

devices are compatible with parallel mode SCXI modules.

Although you can sample signals through an SCXI module at up to

4 MS/s, the SCXI module reduces the available analog bandwidth.

Recommended Software

National Instruments measurement services software, built around

NI-DAQmx driver software, includes intuitive application programming

interfaces, configuration tools, I/O assistants, and other tools designed

to reduce system setup, configuration, and development time. National

Instruments recommends using the latest version of NI-DAQmx driver

software for application development in NI LabVIEW, LabWindows/CVI,

and Measurement Studio. To obtain the latest version of NI-DAQmx, visit

speeds up your development with features including:

• A guide to create fast and accurate measurements with no

programming using the DAQ Assistant

• Free LabVIEW SignalExpress LE data-logging software

• Automatic code generation to create your application in LabVIEW;

LabWindows/CVI; LabVIEW SignalExpress; and Visual Studio .NET,

ANSI C/C++, C#, or Visual Basic 6.0

• Multithreaded technology for 1,000 times performance improvements

over basic data acquisition driver software

• More than 3,000 free software downloads to jump-start your project

Easy Multidevice Programming – NI-DAQmx driver software now

supports multidevice tasks for S Series. Synchronizing channels on

multiple devices using the RTSI, PXI, or PXI Express bus is now as simple

as configuring a single data acquisition board. This greatly reduces the

time and complexity involved with multidevice application programming,

and is now available for any combination of S Series devices.

The NI PXIe-6124 is compatible with NI-DAQmx Version 8.8 or later. It

also is compatible with the following versions (or later) of NI application

software: LabVIEW 7.1, LabWindows/CVI 7.1, Measurement Studio 7.1,

or LabVIEW SignalExpress 3.0.
