This unit
The Anritsu 68259B is a synthesized signal generator delivering precise RF signal generation across 10 MHz to 26.5 GHz with 1 Hz resolution. Built for demanding RF component testing and system simulation, it combines low phase noise, wide dynamic range, and stable frequency synthesis with analog modulation and sweep capabilities. Output spans -127 dBm to +10 dBm with ±1.0 dB accuracy at +10 dBm.
Phase noise reaches -100 dBc/Hz at 1 kHz offset (10 GHz carrier). The instrument supports AM and FM modulation
AM depth to 100%, FM deviation to 200 kHz - plus three sweep modes with selectable trigger sources. Fast frequency switching under 100 ms and frequency stability better than 5×10⁻⁸ per hour enable reliable testing in development and production.
Interfaces include Type-N female RF output, GPIB, Ethernet 10/100 Base-T, and USB. Control via Anritsu Signal Generator Control Software or third-party automation tools. Dimensions: 177 mm H × 436 mm W × 416 mm D; 22 kg.
Rated 100–240 VAC, 50/60 Hz, 400 VA maximum.

Anritsu 68259B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Anritsu 68259B. 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 68259B 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.
