LX500 - Precision Audio & Acoustic Analyzer

Big Features - Small Package !

With a footprint smaller than a sheet of paper the LX500™ contains an impressive array of powerful features and capabilities unmatched in any analyzer this size and price.

Designed for maximum flexibility in both permanent and portable applications the LX500™ is powered by a single 12VDC power source.

The small size and light weight of the LX500™ enables it to be carried by hand, tossed in a brief case, placed on a desktop, easily installed in a permanent engineering lab, or in a demanding production QC environment.

Featuring both Frequency Domain, Time Domain, and Dual Domain versions the LX500™ supports a vast array of different measurement types, techniques, and methods.

Dual Analog Oscillators, Triple Multi-Function Inputs, Precision Noise Generator, Programmable Filter, extensive Bandwidth / Weighting Filters, Phase Meter, High Resolution Digital Signal Generator / Spectrum Analyzers, Digital I/O Control, and comprehensive Windows Application software are only some of the outstanding features and advanced capabilities offered by the LX500™.
