This unit

The Anritsu 68237B is a synthesized signal generator delivering precision RF and microwave signals across 2–20 GHz for demanding component, subsystem, and communication equipment testing. Its phase-locked architecture generates stable outputs with ultra-low SSB phase noise at –100 dBc (10 kHz offset, 10 GHz), supporting continuous wave, step sweep, manual sweep, and analog sweep modes. The instrument provides internal AM, FM, phase, and pulse modulation alongside external modulation inputs.


Up to 20 independent, pre-settable markers (F0–F9, M0–M9) enable precise frequency identification during analog and step sweeps. Output power spans –125 dBm to +17 dBm maximum, leveled in 0.01 dB steps to –120 dBm. Harmonic distortion remains below –60 dBc across 2–20 GHz, with non-harmonic distortion below –60 dBc from >2 GHz to ≤67 GHz.


Frequency resolution reaches 0.1 Hz with Option 11; step size ranges 1 kHz to full span with adjustable dwell times from 1 ms to 99 seconds. Switching speed is typically <15 ms plus 1 ms/GHz step size, or <40 ms (whichever is less); steps <100 MHz switch in <5 ms. The instrument ships in rackmount form factor and supports SCPI programmability via Option 19 (IEEE 488.2–1987).

Anritsu 68237B — Repair & Calibration Service

Aumictech offers NIST-traceable calibration and repair for the Anritsu 68237B. 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 68237B 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.
