This unit
The Anritsu MG3693B is a synthesized signal generator delivering RF and microwave frequencies from 2 GHz to 30 GHz, with external multiplier capability extending coverage to 325 GHz and beyond. It has frequency resolution to 10 mHz and typical output power of +23 dBm, supporting amplitude accuracy of ±0.4 dB. The instrument integrates advanced modulation capabilities
AM (0 to 90%), FM (up to 10 MHz deviation at 8 MHz rates or 100 MHz deviation at 100 Hz rates), and PM (up to 400 radians deviation at 1 MHz rates) - alongside technology-leading phase noise performance and spectral purity.
Internal generators deliver seven modulating waveforms for AM, FM, and phase modulation, while custom waveform download and IQ modulation via IF input enable flexible signal generation for R&D, manufacturing, and system-level testing in wireless communications, radar, and advanced microwave applications.

Anritsu MG3693B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Anritsu MG3693B. 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 MG3693B 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.
