This unit
The Rohde & Schwarz SMP04 is a microwave signal generator delivering precision frequency synthesis across 2 GHz to 40 GHz, with optional extension down to 10 MHz. It combines Direct Digital Synthesis technology with output power ranging from -20 dBm to +12 dBm (depending on frequency band) and exceptional spectral purity
SSB phase noise below –105 dBc/Hz at 10 GHz offset by 10 kHz. The instrument supports broadband modulation across AM, FM, Pulse, Phase, FSK, and ASK modes, with optional precision FM/ΦM and pulse generator capabilities.
Frequency setting time is <11 ms + 5 ms/GHz, and frequency resolution reaches 0.1 Hz. A built-in crystal reference provides 0.000001/yr timebase stability, with OCXO option available. Sweep functionality includes manual step, linear, and list modes.
The instrument stores up to 50 complete setup configurations and operates with 50 Ohm output impedance. Harmonics suppress to <–30 dBc below 1.8 GHz and non-harmonics to <–60 dBc up to 20 GHz. Target applications span microwave component characterization, radar and communication equipment testing, and EMC validation in development and production environments.

Rohde & Schwarz SMP04 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Rohde & Schwarz SMP04. 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 SMP04 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.
