This unit
The Anritsu 68137B Synthesized Sweep Generator delivers phase-locked signal generation across 2–20.0 GHz for RF and microwave component testing, system validation, and production environments. This instrument combines rapid frequency switching, ultra-low phase noise, and flexible sweep modes - including analog, step, manual, and alternate sweep configurations - with programmable frequency agility supporting up to 1000 non-sequential frequencies under GPIB control. Engineers rely on it for demanding test scenarios requiring low-distortion outputs and precise modulation control.
Technical Specifications
- Frequency range: 2–20.0 GHz
- Output impedance: 50 Ω
- Maximum output power: +17 dBm (leveled to 20 GHz)
- Minimum output power: −125 dBm
- Frequency resolution: 0.1 Hz (optional)
- Phase noise: −101 dBc/Hz (minimum) and −54 dBc/Hz (maximum) single-side-band at 20 GHz
- Harmonics: −35 dBc (typical)
- Switching time: <15 ms + 1 ms/GHz step size or <40 ms (whichever is less); <5 ms for steps <100 MHz
- Dwell time per step: 1 ms to 99 seconds (variable)
Key Features
- Broad and narrow-band sweep modes with user-selectable step counts (1 to 10,000) or step sizes (1 kHz to full range)
- Sweep width independently selected from 1 kHz to full frequency range
- Alternate sweep mode: sweeps between two ranges with independent power levels per range
- Manual sweep mode: phase-locked frequency stepping with user-configurable steps
- Programmable frequency agility: addresses up to 1000 stored frequencies as phase-locked step sweep
- Internal AM, FM, phase modulation, and pulse modulation with swept delay
- External AM (log or linear) and external FM (locked or unlocked)
- Flexible pulse triggering: free-run, delayed, gated, and composite modes
- Front-panel control with GPIB remote interface
Typical Applications
- Component and subsystem testing across X, Ku, and K bands
- System validation and characterization
- Automated production test and burn-in
- Radar and satellite signal simulation
Compatibility & Integration Fully programmable via GPIB; front-panel operation supported. Frequency settings and sweep parameters stored in volatile memory under remote control.

Anritsu 68137B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Anritsu 68137B. 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 Anritsu 68137B 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.
