Rohde & Schwarz FS315 Spectrum Analyzer
The Rohde and Schwarz FSH315 is a highly accurate spectrum analyzer with a frequency range of 9 kHz to 3 GHz. Due to its
modern, digital frequency processing technology it offers high measurement quality, high dynamic range and low noise floor
at a favorable price. The FS315 includes a tracking generator, expanding the field of applications to scalar transmission
and reflection measurements. Whether on a lab bench, in service or as a measuring instrument in automatic production systems,
the range of applications is practically unlimited.
The FS300 and FS315 are part of the Smart Instruments™ family, representing a class of affordable high-quality measuring
instruments. This series of instruments is notable for its highly compact and robust design characteristics.
A software package (FS315-K1) is included for remote control of the instrument via a USB interface. The software allows
configuration, operation and display of measurement results on a PC. Measurement traces can be stored, compared with previous
measurements, and exported in txt-format for further offline analysis.
Features And Benefits
