Waveform editor

Design and test engineers can now create and edit test signals with National Instruments’ new Analog Waveform Editor.

The software can be integrated with NI arbitrary waveform generators, analog output devices, data acquisition devices and third-party traditional instruments for signal generation in prototyping and test applications.

The Analog Waveform Editor is a graphical tool that offers 20 built-in waveform primitives such as sine, chirp and impulse. Engineers can simulate a real-world stimulus by adding Gaussian noise, uniform white noise or periodic random noise to a signal created with the editor or imported from a data file.

To create complex waveforms with the editor, engineers can combine waveform primitives using addition, subtraction, multiplication and division operators. They also can enter an equation for more sophisticated waveforms. Using the equation editor, engineers can draw from 40 trigonometric and operational functions such as hyperbolic sine and rounding. The editor offers cut and paste functions to help engineers manipulate waveform data.

With intelligent hard disk caching, the Analog Waveform Editor can handle large waveforms commonly used in data communications, data storage and audio/video tests. Using its advanced memory management, the editor can produce waveforms up to 1GS in length.

To view or edit existing waveforms with the Analog Waveform Editor, engineers can open files saved in a range of open file formats such as ASCII or the LabVIEW 7 Express .lvm file format.

The editor also can export waveforms in standard file formats that work with a variety of application development packages, including NI LabVIEW, NI LabWindows/CVI and Microsoft Visual Studio .NET.

Engineers then can generate the waveforms using hardware, such as NI arbitrary waveform generators and analog output modules, as well as traditional instruments from third-party vendors.

The Analog Waveform Editor complements the NI Digital Waveform Editor that was released in August 2003.
