The pre-owned R&S FSC6 brings laboratory-grade spectrum analysis to benchtops and field kits in a sub-5 kg form factor. Covering 9 kHz to 6 GHz with 10 Hz to 3 MHz RBWs, it cleanly resolves narrow-band emissions as well as broadband modulations, while a typical -161 dBm noise floor with the B22 pre-amplifier exposes faint spurs for EMI or IoT work.

Phase-noise performance below -95 dBc/Hz at 30 kHz offset keeps ACPR and EVM results trustworthy. USB and LAN connectivity enable fast remote automation, and 12 W low-power operation reduces rack-cooling overhead. Supplied fully tested, freshly calibrated and loaded with current firmware, this second-hand unit ships immediately and delivers sizable budget relief without compromising measurement precision or 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.
