Virtual Instrument Aiming To Extend The Capabilities Of The Spectrum Analyzers

摘要

The paper presents a virtual instrument for measuring the insertion loss, signal-to-noise ratio, carrier-to-noise ratio and frequency response. Since most of the spectrum analyzers are equipped with a GPIB or RS-232 interface, here demonstrate that LabVIEW graphical environment represents the proper tool to develop such applications. Sometimes, instrument producers provide specific software, but using LabVIEW some additional costs can be eliminated by user developed software.
