Description
Keysight M8194A Waveform Generator Repair
The Keysight M8194A is an ultra-high-speed arbitrary waveform generator — an AXIe modular AWG with very high sample rate (to ~120 GSa/s) for generating wideband, high-baud signals in advanced communications, optical, and research applications. As a precision high-speed source, its faults concentrate in the high-speed DAC/output stage, the clock/synthesizer, and the AXIe/control interface.
June Company repairs and calibrates the Keysight M8194A for advanced communications, optical, and research teams.
Common Keysight M8194A problems we fix
- Frequency-synthesizer phase-lock errors — the clock/synthesizer drifting or failing to lock, repaired and recalibrated.
- Modulation / output distortion — the high-speed DAC/output stage producing distorted signals, repaired.
- No output or wrong amplitude — output-stage failure, repaired.
- AXIe / control-interface faults — the module not initializing in the chassis, restored.
- A channel dead — per-channel faults, repaired.
FAQs
My M8194A won’t lock or output is distorted — fixable? Yes. Synthesizer and DAC/output faults are repairable, then recalibrated so timing, amplitude, and waveform fidelity are restored, with a NIST-traceable certificate.
Is the output level verified? Yes — amplitude and timing are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
