This unit
The Agilent/Keysight N5161A MXG ATE Analog Signal Generator delivers RF stimulus for automated test equipment environments without a front-panel display. This headless architecture enforces remote operation via SCPI commands or web-enabled interface, making it purpose-built for rack-mount systems and ATE integration. As a streamlined variant of the N5181A MXG, It has equivalent performance with simplified maintenance design.
Note: This product is obsolete; the N5181A MXG X-Series is the current replacement.

Agilent / Keysight N5161A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight N5161A. 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 Agilent / Keysight N5161A 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.
