Data Merging and Extraction Combining data from individual channels of different wave files, and extracting part of data from a wave file are supported. The figure shown on the slide shows the timing diagram for high-level digital pause triggering.
Why not integrate them as exemple in labview to help passing to daqmx The timing involved in using the "task" nidaqmx functions is unacceptable. Wave files with PCM format or properly formatted text file can be imported for analysis.
This example is intended to show low level synchronization of various devices. I would kindly ask NI to keep on supporting its native programming environment. Maybe there is a zip i can download for the examples.
NI wants to sell us LabView, talks only about LabView, prepare documentation and examples using LabView and send brochures and ads about it all time.
You can integrate Multi-Instrument into your own software seamlessly via the ActiveX automation server interfaces exposed by Mutil-Instrument. Once the trigger conditions are met, the ATC generates an internal trigger signal to initiate the acquisition. You connect analog trigger signals to any analog input channel or terminal capable of accepting analog signals.
You can use this VI to specify the source of the trigger and the desired edge to trigger on. A long wave file can be imported frame by frame either manually or automatically.
I too would like to see a similar document addressing labwindows transition. The edge, minimum value and maximum value are all configurable.
One can then adjust the equalizer to make an inversed frequency response such that the combined frequency response is flat or aligned to the preference of the audiences. Software Customization Multi-Instrument provides the following user customizable features: Normally pink noise is used as the test tone and octave analysis is set in the spectrum analyzer.
The reference curve can be configured by either copying the current curve, or loading a properly formatted text file or a previously saved reference file from the hard disk.
In the figure below each rising edge of the sample clock signal indicates the initiation of a scan: In such a system, analog trigger circuitry ATC on the DAQ hardware continuously monitors the analog signal to determine if it satisfies the trigger conditions.
Graph Operation Zooming and Scrolling is supported in all graphs, allowing you to investigate the fine details of the data. The trigger deasserts when the signal crosses below level minus hysteresis. This example program exports the sample clock from the device.
Five chart types are supported: This example shows how to configure the pulse in terms of frequency and duty cycle, but it can easily be modified to generate a pulse in terms of time or ticks.View and Download National Instruments Data Acquisition Device NI USBx user manual online.

Updated Aug 2, In LabVIEW, a DAQmx Write property node can be used to manipulate the way data is written into the buffer and to disable regeneration.
The specific properties of interest in this case is RegenMode property. Dynamic/Programmatic Analog Output Using NI-DAQmx; Other Support Options. This example shows the difference between performing continuous analog input with an internal clock in Traditional NI-DAQ (Legacy) and NI-DAQmx.
