Used RF Spectrum Analyzer Rohde & Schwarz FSV4 4 GHz Wideband Spectrum Analyzer

The pre-owned R&S FSV4 combines lab-grade spectrum and vector-signal analysis from 10 Hz to 4 GHz with optional 160 MHz instantaneous capture, enabling precise EVM, ACPR and spur checks on WLAN, LTE and radar waveforms without external mixers.

With typical phase-noise of -110 dBc/Hz and a -155 dBm noise floor (with the 20 dB pre-amp), this analyzer reveals faint emissions. Upgrade-keys for tracking generation, baseband I/Q and VSA apps extend functionality as needed. Each unit ships fully tested, freshly calibrated with current firmware, offering Rohde & Schwarz accuracy, automation via LAN/GPIB, and significant cost savings compared to new equipment.

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.
