The pre-owned Rohde & Schwarz FSQ3 combines high-dynamic-range spectrum analysis with vector-signal analysis in a single 20 Hz to 3.6 GHz platform.
Optional 120 MHz acquisition bandwidth enables precise characterization of wide-channel WLAN, LTE and radar waveforms, while a typical −128 dBc/Hz phase-noise floor and −158 dBm sensitivity reveal low-level spurs and maintain tight EVM and ACLR margins.
Supplied fully tested, freshly calibrated and loaded with current firmware, each unit ships from stock—delivering immediate lab-grade performance and LAN/GPIB automation at a fraction of new-instrument cost.
