This unit
The Rohde & Schwarz SMB100B RF Signal Generator delivers precise signal generation across multiple frequency bands from 8 kHz to 40 GHz, with extension to 170 GHz via the R&S®SZM frequency multiplier. Engineered for R&D, production, and service environments, this instrument combines excellent signal purity with flexible modulation and wide dynamic range in a compact platform.
Technical Specifications
Frequency Coverage RF variants span 8 kHz to 1 GHz, 3 GHz, or 6 GHz. Microwave variants extend to 12.75 GHz, 20 GHz, 31.8 GHz, or 40 GHz. Frequency multiplier option enables operation to 170 GHz. Signal Purity SSB phase noise reaches -134 dBc at 1 GHz (20 kHz offset, 1 Hz bandwidth) and better than -112 dBc at 10 GHz (20 kHz offset). Wideband noise measures -153 dBc typical at 1 GHz (30 MHz offset) and below -145 dBc across frequency ranges. Harmonic suppression exceeds -55 dBc above 2 GHz at full output power. Non-harmonic suppression is -82 dBc at 1 GHz and -64 dBc at 10 GHz. Output Power Standard output reaches +26 dBm from 1 MHz to 6 GHz, with +20 dBm typical to 12.75 GHz and +18 dBm to 20 GHz. Maximum power climbs to 34 dBm at 1 GHz, 25 dBm at 20 GHz, and 19 dBm at 40 GHz. Optional high-power configuration delivers +28 dBm at 1 GHz or +24 dBm to 20 GHz. Minimum level is -127 dBm (frequencies above 10 MHz), yielding 153 dB dynamic range. Level Accuracy Accuracy stays below 0.5 dB from 200 kHz to 3 GHz at levels exceeding -90 dBm, and below 0.7 dB above 3 GHz at the same power threshold.Key Features

Rohde & Schwarz SMB100B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Rohde & Schwarz SMB100B. Calibration covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Rohde & Schwarz SMB100B faults: YIG oscillator failure (no output or loss of lock), step attenuator wear (output drops or steps at set attenuation), ALC loop failure (uncontrolled output power), I/Q modulator assembly failure. HP/Agilent 836xx series most common faults are YIG oscillator failure and step attenuator contact wear causing output steps or drops at specific attenuation settings. Keysight E4428C/E4438C units most commonly develop ALC loop failure and I/Q modulator assembly faults. YIG oscillator replacement and attenuator service are stocked repairs.
