This unit
The Keysight (Agilent) 3326A is a dual-channel synthesizer generating precise signals from DC to 13 MHz with independent control of frequency, amplitude, and modulation on each output. Microprocessor control enables coordinated sweeping, phase-continuous frequency changes with 11-digit resolution, and HP-IB programmability. The instrument delivers sine and square waveforms with 0.01 dB amplitude resolution across eight selectable ranges (1 mV p-p to 10 V p-p), supporting AM, PM, frequency sweeping, two-tone generation, and pulse mode with variable symmetry.
All outputs are floating with an internal signal combiner and adjustable DC offset.
Technical Specifications
Frequency Range: DC to 13 MHz Frequency Resolution:- 1 µHz below 100 kHz
- 1 mHz from 100 kHz to 13 MHz
- 11 digits for phase-continuous sweeps and frequency changes Frequency Stability: ±0.2 degrees below 100 kHz with internal calibration; external calibration and Option 001 (High Stability Frequency Reference) available for extended accuracy requirements. Output Amplitude: 1 mV p-p to 10 V p-p in eight ranges with 0.01 dB resolution. Floating outputs on both channels; rear panel output option available (Option 003). Waveforms: Sine and square, independently selectable per channel. Sinewave distortion: harmonics ≤ -70 dBc below 100 kHz. Modulation:
- AM: DC to 100 kHz, envelope distortion better than -46 dB
- PM: 0.01-degree phase resolution across entire 13 MHz range
- Two-tone: ±100 kHz channel offset in CW or sweep modes
- Pulse mode: 1% to 99% symmetry in 0.1% increments Sweep Modes: Coordinated dual-channel sweeping. Discrete mode supports 2 to 63 frequency pairs with individual dwell times per frequency and channel. Sweep time range: 5 ms to 1000 s.

Keysight / Agilent 3326A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent 3326A. 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 Keysight / Agilent 3326A 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.
