RIGOL Equipment We Repair — By Category
RIGOL Product Lines We Repair
Our engineers are trained on the full RIGOL product range. Below are the major product families we service.
DS/MSO Series Digital Oscilloscopes
High-bandwidth portable and benchtop oscilloscopes for signal capture, waveform analysis, and protocol decoding. Common faults include LCD display failures, input coupling capacitor degradation, timebase circuit instability, and vertical amplifier saturation.
DG Series Arbitrary Waveform Generators
Function and arbitrary waveform generators used for signal simulation, frequency response testing, and component validation. Typical failures include output attenuator relay sticking, DAC reference voltage drift, and front-panel control processor faults.
DP Series Programmable DC Power Supplies
Multi-channel regulated power supplies for bench testing and automated test systems. Repair-critical issues involve output voltage ripple due to filter capacitor ESR drift, remote sensing line noise, and switching regulator IC failures.
DH Series High-Voltage DC Power Supplies
Precision high-voltage isolated power supplies for industrial testing and component characterisation. Common faults include high-voltage transformer insulation breakdown, rectifier diode failure under transient load, and regulation circuit oscillation.
DL Series Programmable Electronic Loads
Programmable DC load units for power supply testing, battery discharge profiling, and thermal chamber simulation. Failures typically stem from output FET thermal stress, feedback sensing circuit drift, and current control loop oscillation.
RSA Series Spectrum Analysers
Real-time spectrum analysers for RF/microwave signal monitoring and interference detection. Repair concerns include RF frontend mixer crystal ageing, intermediate frequency filter resonance shift, and display processor memory corruption.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common RIGOL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RIGOL equipment arriving at our workshop.
- ✓RIGOL oscilloscope vertical channel no signal display — Input coupling capacitor (C1, C2, C3, C4) develops open-circuit mode due to age and moisture ingress, blocking AC signals at the probe connector. This is especially common in humid Indian warehouse and outdoor field-test environments.
- ✓RIGOL power supply output voltage drifts during load changes — Electrolytic filter capacitors (100µF to 1000µF bulk storage types) experience ESR (equivalent series resistance) increase from thermal cycling and age, degrading transient response. DP and DH series supplies are particularly susceptible in high-temperature industrial settings.
- ✓RIGOL waveform generator output amplitude unstable or attenuated — Output attenuator relay contacts oxidise or mechanically stick in fixed attenuation state; parallel, DAC reference voltage reference IC (typically REF5050) drifts due to thermal stress or component ageing, causing amplitude miscalibration across frequency ranges.
- ✓RIGOL spectrum analyser no RF signal reception or weak sensitivity — RF input mixer diode crystal (typically used in down-conversion stage) exhibits frequency shift or loss of non-linearity due to age and thermal stress; front-end LNA (low-noise amplifier) IC fails or input matching network capacitor drifts.
- ✓RIGOL electronic load current control loop unstable — oscillating output — FET output stage thermal stress causes transconductance (gm) variation; feedback sense resistor tolerance drift or cold-solder joint on current-sense amplifier IC (e.g., INA128, OPA2333) introduces delay in feedback loop, causing oscillation.
- ✓RIGOL oscilloscope triggering unreliable — triggers miss pulses or are delayed — Comparator IC (trigger circuit) degradation due to electrical overstress (EOS) from input transients; trigger coupling capacitor age causing charge-time constant shift; timebase crystal oscillator frequency drift from thermal cycling.

Frequently Asked Questions — RIGOL Repairs
Do you repair RIGOL equipment anywhere in India?+
Yes. Synchronics repairs the full RIGOL test and measurement product range — oscilloscopes, waveform generators, power supplies, electronic loads, and spectrum analysers. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all other cities. All repairs are performed at our central facility in Vadodara, Gujarat, with the same expert team.
What is the typical turnaround time for RIGOL oscilloscope repairs?+
For most RIGOL DS and MSO series scope faults (vertical channel issues, display problems, probe connectivity) Synchronics delivers repair within 7-10 working days from receipt. Complex issues involving trigger circuit failures or full calibration may take 10-14 days. We provide daily status updates and expedited service for critical production environments.
Do you provide calibration certificates for repaired RIGOL equipment?+
Yes. Every repaired RIGOL instrument receives factory-standard calibration verification using traceable reference standards. We issue an official calibration certificate documenting bandwidth, frequency accuracy, amplitude linearity, and trigger sensitivity across the operating range. Certificates are required for pharma, automotive, and defence sector compliance.
Can you repair RIGOL power supplies with custom voltage or current ratings?+
Synchronics repairs standard DP, DH, and DL series supplies within their rated specifications. Custom or heavily modified supplies require detailed technical documentation. We assess feasibility during initial inspection and provide a transparent repair quote. Most Indian manufacturing facilities use off-the-shelf RIGOL models, which we service routinely.
What warranty do you provide on RIGOL repairs?+
All RIGOL repairs from Synchronics carry a 12-month warranty on replaced components and repairs performed. If the same fault recurs within 12 months, we repair at no charge. For power supplies and high-reliability applications, we offer extended 24-month coverage at nominal cost. Warranty terms are clearly stated in the repair invoice.
How do I send my RIGOL 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 RIGOL 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 RIGOL 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 RIGOL 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.
