This unit
The Rohde & Schwarz SMGU is a synthesized signal generator delivering precise RF and microwave signal generation from 100 kHz to 2160 MHz. Built for research, development, and production environments, it combines exceptional spectral purity with comprehensive modulation capabilities and fast frequency switching. The instrument excels at receiver testing, adjacent-channel measurements, and low-noise reference applications, offering output power from -140 dBm to +13 dBm with 0.1 Hz frequency resolution.

Rohde & Schwarz SMGU — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Rohde & Schwarz SMGU. 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 SMGU 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.
