New SpectrumWare Software Simplifies Dynamic Signal Analysis

Program Included with Company's Dynamic Signal Acquisition Boards Free of
Charge

October 20, 1993 -- Austin, TX - National Instruments announced today a
dynamic signal analyzer virtual instrument (VI) for Windows, Macintosh,
and Sun users. Users can combine SpectrumWare and the company's dynamic
signal acquisition boards for PC AT, EISA, NuBus, or SBus computers in a
variety of electrical, acoustical, and mechanical applications. With a
frequency range of DC to 22 kHz, and a dynamic range of 93 dB, the plug-in
dynamic signal acquisition boards and Spectrumware provide high-accuracy
performance for a wide range of applications.

SpectrumWare has an easy-to-use graphical user interface (GUI) that
simplifies the measurement of frequency response, power spectrum,
amplitude spectrum, coherence, transient capture, cross spectrum, and
total harmonic distortion (THD). It is ideal for applications involving
electronic filters and networks, audio frequency communications equipment,
machine vibration, transducers such as accelerometers and hydrophones,
resonances in mechanical structures, or acoustic tests. Other applications
include the measurement of transient signals or the spectra of
low-frequency signals such as speech or mechanical vibration.

The SpectrumWare executable program was built using the company's new
LabVIEW Application Builder. With Application Builder, LabVIEW users can
create VIs that operate as stand-alone executables. Once selected,
SpectrumWare will load, execute, and unload automatically. The LabVIEW
source code for SpectrumWare can be edited with LabVIEW version 3.0, so
users can alter and customize it for their individual applications.
