HP / Agilent 3311A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 3311A. Calibration covers output frequency accuracy, output amplitude accuracy at 50 ohm and Hi-Z load, DC offset accuracy, symmetry and duty cycle accuracy, and arbitrary waveform sample rate accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common HP / Agilent 3311A faults: BNC output connector wear, output amplifier failure from short-circuit drive, display and keypad membrane switch wear, DDS or DAC failure on 33250A. HP 33120A and Agilent 33220A most common fault is BNC output connector wear from repeated cable insertions. Output amplifier failure on the HP 33120A typically results from sustained short-circuit drive. Agilent 33250A DDS and high-speed DAC failures are rare but require component-level repair and post-repair amplitude verification across the full 80 MHz range.
HP / Agilent 3311A price
This HP / Agilent 3311A is listed at $350.98. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
HP / Agilent 3311A calibration cost
NIST-traceable calibration for the HP / Agilent 3311A is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers output frequency accuracy, output amplitude accuracy at 50 ohm and Hi-Z load, DC offset accuracy, symmetry and duty cycle accuracy, and arbitrary waveform sample rate accuracy. Turnaround is 1 to 3 business days after receipt. See full calibration details →
