This unit
The Anritsu 69259A is a synthesized signal generator spanning 0.01 to 26.5 GHz, engineered for RF device characterization, modulator analysis, and EMC testing. It delivers precise output power control from −125 dBm to +17 dBm with ultra-low phase noise (−136 dBc/Hz SSB at 10 GHz). The instrument supports internal AM, FM, phase, and pulse modulation alongside user-downloaded complex waveforms.
Step sweep functionality addresses up to 1000 non-sequential frequencies with <15 ms typical switching time, while analog sweep operates across programmable ranges with selectable linear or logarithmic profiles. Alternate sweep mode enables bidirectional frequency sweeping between two independent ranges. Frequency stability is anchored to an internal 10 MHz time base with aging drift <2 × 10⁻⁸/day and temperature coefficient <2 × 10⁻⁸/°C over 0–55 °C.
External 10 MHz reference input and output are provided for synchronization with external equipment.

Anritsu 69259A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Anritsu 69259A. 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 69259A 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.
