MSA-4930 Spectrum Analyzer
The end of production

msa4930

The MSA-4930, Spectrum Analyzer, with much elevation on the frequency domain technology, is positioned as an accurate and powerful equipment for RF measurements in the industrial fields. The 3GHz Frequency band(9kHz to 3GHz)and the Low noise floor of -117dB greatly
expands the MSA-4930 dynamic range to a level that meets most of the critical measurement requirements in various market sectors.
The optional filters plus Averge and Quasi-Peak Detections fullfill the demand for EMI test compliances. The fucntion of"Peak Table", listing the first ten peaks based on the ranking of either amplitude or frequency, provides EMI engineers with a very convenient equipment. The
MSA-4930 provides multiple PC connections. In addtion to the standard RS-232C and optional GP-IB for remote control, this unit now includes the widely adopted USB Host for data tranfer and display printout. In addition to the light-weight & compact design, DC power of automobile cigar lighter/Battery power operation give field service engineers the best portability benefit.
