The pre-owned R&S FSH3 packs laboratory-grade spectrum analysis into a 2.5 kg field unit that runs up to four hours on battery power. Covering 100 kHz to 3 GHz with 1 kHz–1 MHz RBWs, it supports cable fault-location and scalar network measurements when the optional tracking generator is fitted.
Typical phase noise below –100 dBc/Hz and a –116 dBm noise floor are sufficient for on-site ACPR, channel-power and EMI checks, while the optical RS-232 interface simplifies PC logging. Supplied fully tested, freshly calibrated and firmware-current, this handheld analyzer offers immediate availability and significant cost savings over new instruments without compromising measurement accuracy or Rohde & Schwarz reliability.
