Rohde & Schwarz R&S FSH4 Handheld RF Spectrum Analyzer 3.6 GHz

The pre-owned Rohde & Schwarz FSH4 compresses lab-grade RF capability into a rugged 3 kg handheld that operates for more than four hours on battery power.

Covering 9 kHz – 3.6 GHz with 1 Hz RBW and a −161 dBm noise floor, it confidently hunts spurs, validates wireless links and, with the optional tracking generator and VSWR bridge, performs cable-fault and scalar network tests.

Standard USB/LAN remote control streamlines automated data logging, and each unit ships freshly calibrated and firmware-current for immediate field deployment at a fraction of new-instrument cost.
