The pre-owned R&S FSL3 delivers lab-grade spectrum analysis from 9 kHz to 3 GHz in a sub-8 kg chassis, ideal for production lines, service labs and field troubleshooting. A 28 MHz demodulation path captures today’s wide-channel WLAN, Bluetooth and IoT signals, while phase noise around –103 dBc/Hz and a pre-amp-enabled noise floor near –158 dBm expose low-level spurs and EMI emissions with confidence.
Optional GPIB, LAN/IF and internal pre-amplifier upgrades safeguard remote automation and sensitivity growth, and each used unit ships freshly calibrated and firmware-current—offering immediate availability and significant capital savings without sacrificing measurement accuracy or Rohde & Schwarz reliability
