The pre-owned R&S FS300 delivers dependable spectrum analysis from 9 kHz to 3 GHz in a compact, cost-effective enclosure. Sixteen digitally implemented RBWs down to 200 Hz and a typical –115 dBm noise floor let engineers spot weak emissions even in the presence of strong carriers, while < –90 dBc/Hz phase noise keeps ACPR and spur measurements trustworthy.
USB-based remote control and bundled PC software streamline automated logging and report generation, and optional probes or pre-amplifiers expand EMI-debug capability.
Fully tested, freshly calibrated and firmware-current, each unit ships from stock—providing immediate deployment and significant savings versus new entry-level analyzers without sacrificing Rohde & Schwarz reliability.
