Description
The Rigol DSA875 is a compact and light weight Spectrum Analyzer with premium performance for portable applications. The use of digital IF (intermediate frequency) technology guarantees reliability and performance to meet the most demanding RF applications. The very large display (20.3 cm / 8″) of the Rigol DSA875 Spectrum Analyzer provides a resolution of 800×480 pixels allowing a very good overview of all its comfortable functions like Auto Tune, Auto Range, Auto Scale and Auto Couple. These functions enable the analyzer to acquire signals and match parameters automatically, compared to the manual process necessary with a traditional analyzer. The Rigol Spectrum Analyzers have a sophisticated and easy to use user interface offering multiple functions for all tasks. The menu navigation is very intuitive and all functions and parameters are easy to locate thanks to the graphical interface.
