EM TEST Equipment We Repair — By Category
EM TEST Product Lines We Repair
Our engineers are trained on the full EM TEST product range. Below are the major product families we service.
SURGE 3000 Series
High-voltage surge testing generators used for IEC 61000-4-5 compliance. Tests immunity to lightning-induced and switching transients. Common issues include coupling capacitor degradation, high-voltage transformer saturation, and trigger circuit failures.
EFT 3000 Series
Electrical fast transient burst generators for IEC 61000-4-4 testing. Generates high-frequency transient bursts to validate industrial equipment immunity. Repair focus includes burst output regulation failures, coupling clamp insulation breakdown, and control board reset loops.
NSG 3000 Series
Noise simulation generators for conducted immunity testing per IEC 61000-4-6. Used by automotive and pharma industries for product validation. Common faults: RF output power loss, frequency synthesis instability, and temperature-dependent frequency drift.
ESD 3000 Series
Electrostatic discharge simulators for contact and air-gap ESD testing per IEC 61000-4-2. Critical for electronics and semiconductor manufacturing. Typical issues: discharge capacitor leakage, high-voltage connector arcing, and pulse timing accuracy loss.
Control Interface & Coupling Networks
EM TEST proprietary coupling clamps, coupling networks, and CDN (Coupling Decoupling Networks) for transient immunity tests. These are high-reliability passive and active matching circuits. Faults include capacitor dielectric breakdown, inductor saturation, and matching impedance drift.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EM TEST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EM TEST equipment arriving at our workshop.
- ✓SURGE 3000 output voltage regulation dropout — High-voltage transformer primary winding insulation breakdown or arcing in the voltage divider network due to humidity ingress or partial discharge. Common in monsoon-prone regions of India.
- ✓EFT 3000 burst pulse frequency instability or jitter — Phase-locked loop (PLL) component aging or thermal drift in the RF synthesizer board. Temperature fluctuations during testing or inadequate thermal management lead to frequency wandering outside test specifications.
- ✓NSG 3000 RF output power loss below 20 dBm minimum — Attenuator pad component failure, RF amplifier bias point drift, or coupling network impedance mismatch. Often triggered by dust accumulation on PCB traces affecting RF coupling efficiency.
- ✓ESD 3000 capacitor bank leakage or pre-discharge failure — High-voltage ceramic or film capacitors developing micro-cracks or dielectric leakage due to repeated discharge cycles. Monsoon humidity accelerates this degradation in uncontrolled factory environments.
- ✓Coupling clamp or CDN connector arcing and contact oxidation — Repeated high-current transient pulses cause contact surface oxidation and micro-arcing in the signal and ground connectors. Poor contact pressure or vibration loosens crimp connections.
- ✓EM TEST control interface communication timeout or display freeze — GPIB or Ethernet interface firmware corruption, real-time clock battery depletion, or power supply ripple on the control board causing processor watchdog resets.

Frequently Asked Questions — EM TEST Repairs
Do you repair EM TEST equipment anywhere in India?+
Yes. Synchronics repairs the complete EM TEST EMC testing and surge simulation portfolio across all of India. We provide same-day pickup from major cities including Pune, Mumbai, Bangalore, Hyderabad, Chennai, Delhi, Ahmedabad, Surat, and Vadodara. All repairs are completed in our 180+ engineer facility in Vadodara, Gujarat, with PAN India door delivery.
Can you repair EM TEST SURGE 3000 and EFT 3000 systems that have lost output voltage or pulse power?+
Absolutely. This is one of our most common EM TEST repairs. We perform comprehensive high-voltage transformer testing, voltage divider network diagnostics, RF amplifier bias analysis, and full output power calibration. We also validate pulse repetition rate, pulse width, and inter-pulse timing to IEC 61000-4 standards before return.
What is your repair turnaround time for EM TEST equipment?+
Standard EM TEST repairs take 7-10 business days from receipt. Complex faults involving multiple high-voltage stages or firmware reloads may take 12-14 days. We provide free diagnostic reports, cost estimates, and expedited repair options for critical production downtime situations. All work includes 6-month warranty.
Do you stock spare parts for EM TEST surge simulators and coupling networks?+
Yes. Synchronics maintains inventory of common EM TEST replacement components including high-voltage capacitor banks, RF amplifier modules, coupling clamp connectors, surge transformers, and firmware EEPROM modules. We also coordinate original parts procurement directly from EM TEST Switzerland for specialized components with 2-3 week lead times.
Can you help with EM TEST equipment calibration and compliance certification after repair?+
Yes. Post-repair, we perform full functional validation and output power calibration per EM TEST factory specifications. We generate detailed calibration reports showing voltage linearity, frequency accuracy, and pulse timing compliance. While formal ISO 17025 recertification requires EM TEST factory labs, our calibration ensures your equipment meets IEC 61000-4 test standards for continued use.
How do I send my EM TEST unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a EM TEST drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on EM TEST repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your EM TEST unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
