DAQMeter DAQCard-4050 User Manual
LabVIEW. The LabVIEW Data Acquisition VI Library is functionally
equivalent to the NI-DAQ software.
LabWindows/CVI features interactive graphics, a state-of-the-art user
interface, and uses the ANSI standard C programming language. The
LabWindows/CVI Data Acquisition Library, a series of functions for
using LabWindows/CVI with National Instruments DAQ hardware, is
included with the NI-DAQ software kit. The LabWindows/CVI Data
Acquisition library is functionally equivalent to the NI-DAQ software.
However, the DAQCard-4050 works only with the Easy I/O functions.
For full functionality, you can use the DAQMeter DAQCard-4050
Instrument Driver with LabWindows/CVI.
Using LabVIEW or LabWindows/CVI software will greatly reduce the
development time for your data acquisition and control application.
VirtualBench
VirtualBench is a suite of VIs that allow you to use your data
acquisition products just as you use stand-alone instruments, but you
benefit from the processing, display, and storage capabilities of PCs.
VirtualBench instruments load and save waveform data to disk in the
same forms that can be used in popular spreadsheet programs and word
processors. A report generation capability complements the raw data
storage by adding timestamps, measurements, user name, and
comments.
The complete VirtualBench suite contains VirtualBench-Scope,
VirtualBench-DSA, VirtualBench-Function Generator,
VirtualBench-FG, VirtualBench-Arb, VirtualBench-AODC,
VirtualBench-DIO, VirtualBench-Board Calibrator,
VirtualBench-DMM, and VirtualBench-Logger. Your DAQCard-4050
kits contains a copy of VirtualBench-DMM. VirtualBench-DMM is a
turn-key application that allows you to make measurements as you
would with a standard benchtop multimeter.
DAQMeter DAQCard-4050 Instrument Driver and NI-DAQ
The DAQMeter DAQCard-4050 Instrument Driver provides flexibility
and programmability in a standard instrument driver format.
The instrument driver application programming interface (API) is
designed after a classical, full-featured digital multimeter instrument
driver. The instrument driver lets you avoid making low-level software
calls. The DAQMeter DAQCard-4050 Instrument Driver works with
