Vibration Test System Repair
Techmaster Electronics provides factory-trained repair of vibration and shock test systems — Brüel & Kjær, PCB Piezotronics, Endevco, Dytran, IMI Sensors, and Crystal accelerometers; LDS, Unholtz-Dickie, and Data Physics shakers; m+p, Vibration Research, and Spectral Dynamics controllers. Every repaired unit returns with a back-to-back NIST-traceable calibration and an ISO/IEC 17025 accredited certificate.
Equipment We Repair
Vibration labs depend on transducers and shakers that hold their sensitivity and frequency response between PMs. Every repair includes a back-to-back comparison against an ANAB-traceable reference accelerometer.
Accelerometers
PCB Piezotronics, B&K, Endevco, Dytran, IMI, and Crystal accelerometers (charge, IEPE/ICP, MEMS, triaxial) — cable refurbishment, hermetic-seal rework, and back-to-back sensitivity re-calibration.
Electrodynamic Shakers
LDS / Brüel & Kjær, Unholtz-Dickie, Data Physics, IMV shakers — armature rewinding, suspension-flexure rework, cooling-blower service, and post-repair sine / random verification.
Vibration Controllers
m+p VibPilot, Vibration Research VR9500/VR10500, Spectral Dynamics LASER, and B&K controllers — DSP board repair, I/O card replacement, and post-repair closed-loop verification.
Dynamic Signal & FFT Analyzers
Brüel & Kjær PULSE, HP / Agilent / Keysight 35670A and 35665A, Data Physics DSA — input-conditioning rework, DSP repair, and post-repair calibration across the analyzer’s rated band.
Also repaired: Charge Amplifiers · ICP Signal Conditioners · Impact Hammers · Force Transducers · Modal Exciters · Slip Tables · Power Amplifiers (Shaker) · Reference Accelerometers · Vibration Meters

Our Repair Advantages
Why aerospace, defense, manufacturing, and healthcare customers trust Techmaster for vibration test system repair since 1989.
90-Day Repair Warranty
Every repair is covered by a 90-day parts-and-labor warranty — if the same failure reoccurs, we repair it again at no charge.
ISO/IEC 17025 Cal Included
Every repaired instrument ships back with a post-repair calibration certificate against ANAB Cert AC-1736 — no separate calibration order needed.
Faster Than OEM
Standard 7–10 business-day repair turnaround vs. 4–8 weeks at the OEM service center. Expedite service available. Free local pickup in Silicon Valley, So-Cal, and Orlando.
Got an accelerometer drift problem or a shaker that won’t hold the test profile?
Our technicians handle PCB Piezotronics, B&K, Endevco, Dytran, LDS, Unholtz-Dickie, m+p, and Vibration Research equipment — including legacy gear the OEM has declared end-of-service.
Frequently Asked Questions
Common questions about vibration test system repair at Techmaster Electronics.
What is the typical turnaround for vibration system repair?
Standard repair turnaround is 7–10 business days for accelerometers, charge amps, and controllers. Shaker armature work (rewinding, suspension service) may require 3–6 weeks depending on parts availability. Expedited service is available.
Do you do back-to-back accelerometer calibration after repair?
Yes. Every repaired accelerometer is back-to-back compared against an ANAB-traceable reference accelerometer across its rated frequency band. The certificate includes sensitivity at 100 Hz, frequency response, and transverse sensitivity.
Can you repair a shaker that has lost armature continuity or moved off-center?
Yes. We rewind shaker armatures (LDS, Unholtz-Dickie, Data Physics, IMV), service flexure suspensions, and re-align armatures — followed by full sine / random verification before shipping. Heavy shakers may require on-site service; contact us for a site visit.
Do you repair legacy B&K / HP / Agilent analyzers?
Yes — legacy support is one of Techmaster’s specialties. We repair B&K PULSE, HP / Agilent 35670A and 35665A series, Spectral Dynamics SD380, and Data Physics analyzers, including models the OEM has declared end-of-service.
What if a transducer can’t be brought back to spec?
We provide a written diagnosis and credit the evaluation fee toward a refurbished or rental replacement. We never charge repair labor on unrepairable units.
Which Techmaster locations perform vibration system repair?
Vibration repair is performed at our Vista CA, Santa Clara CA, Orlando FL, and San Antonio TX laboratories. Free local pickup is available in Silicon Valley, Southern California, and Orlando.
