Rohde & Schwarz FSW43 43.5 GHz Ultra-Wideband Signal Spectrum Analyzer with 2 GHz/8.3 GHz Bandwidth Options
This pre-owned Rohde & Schwarz FSW43 combines fundamental-mixing coverage from 2 Hz to 43.5 GHz with optional 2 GHz or 8.3 GHz instantaneous capture bandwidth. The analyzer enables engineers to characterize 5G FR2, wide-band radar, and satellite links without requiring external harmonic mixers.
| Attribute | Value |
|---|---|
| New / Used | Used |
| Frequency Range | 2 Hz - 43.5 GHz |
| Internal Analysis Bandwidth | up to 2 GHz (Option B2001) / 8.3 GHz (Option B8001) |
| Phase Noise | < -136 dBc/Hz @ 10 kHz offset (1 GHz carrier) |
| DANL | -169 dBm/Hz (150 MHz - 8 GHz, pre-amp off) |
| Interfaces / Options | LAN, GPIB, USB; 30 dB RF pre-amp B24, LO/IF ports B21, 800 MHz real-time analysis upgrade |
Exceptional phase noise floor below -136 dBc/Hz and noise level of -169 dBm/Hz reveal spurious tones that threaten tight EVM or ACLR budgets. The integrated 30 dB pre-amplifier and 800 MHz real-time analysis extend sensitivity and dynamic spectrum monitoring capabilities.
