The pre-owned R&S FS300 delivers reliable spectrum analysis from 9 kHz to 3 GHz in a compact, cost-effective package. With sixteen digitally implemented RBWs down to 200 Hz and a typical -115 dBm noise floor, engineers can detect weak emissions even in the presence of strong carriers, while < -90 dBc/Hz phase noise ensures accurate ACPR and spur measurements.

USB-based remote control and included PC software simplify automated logging and report generation, while optional probes or pre-amplifiers extend EMI-debug capabilities.

Each unit is fully tested, freshly calibrated, and running current firmware. Available from stock, these analyzers offer immediate deployment and significant savings compared to new entry-level models while maintaining Rohde & Schwarz reliability.

Every unit is calibrated at an ISO/IEC 17025 accredited laboratory. The original calibration certificate, marked TESTRO Certified, is linked to the unit's serial number and included in the shipment.
