PXIe-8840 User Manual
NI-DAQmx provides an extensive library of functions that you can call from your application
development environment or interactive environment such as NI Signal Express. These
functions provide an intuitive API for National Instruments multifunction DAQ products.
Features available include analog input (A/D conversion), buffered data acquisition
(high-speed A/D conversion), analog output (D/A conversion), waveform generation,
digital I/O, counter/timer operations, SCXI signal conditioning, RTSI or PXI synchronization,
self-calibration, messaging, and acquiring data to extended memory. For more information

National Instruments Modular Instruments use specialized drivers suited to each product’s
specialization. Express VIs provide customized, interactive programming of instruments in a
single interface and soft front panels provide an interface for testing the functionality of each
instrument with no programming required. NI Switches, DMMs, High-Speed DIO, High-Speed
Digitizers, and Sources each have customized drivers for high-end modular instrumentation
systems. RF applications leverage two drivers, NI-RFSG and NI-RFSA and Dynamic Signal
Acquisition is available through NI-DAQmx. For more information visit

You can expand the timing and triggering functionality of your PXI system with PXI Timing and
Synchronization products. These products provide precision clock sources, custom routing of
triggers for multi-chassis synchronization, clock sharing, and more and are programmed with
NI-Sync. For more information visit

NI-VISA is the National Instruments implementation of the VISA specification. VISA is a
uniform API for communicating and controlling USB, Serial, GPIB, PXI, VXI, and various
other types of instruments. This API aids in the creation of portable applications and instrument
drivers. For information on writing your own PXI instrument driver with NI-VISA, refer to the
NI-VISA Help
and the
readme.txt
file in the NI-VISA directory. For more information visit

With LabVIEW for Linux and support for over two hundred devices on Linux with the
NI-DAQmx driver, you can now create Virtual Instruments based on the Linux OS. Instrument
control in Linux has been improved by the NI-VISA driver for Linux and NI Modular
Instruments are partially supported. For more information visit
