KEYSIGHT Equipment We Repair — By Category
KEYSIGHT Product Lines We Repair
Our engineers are trained on the full KEYSIGHT product range. Below are the major product families we service.
InfiniiVision 2000/3000/4000/6000X Oscilloscopes
Entry to mid-range digital oscilloscopes widely used in Indian electronics labs, manufacturing facilities and educational institutions. Common issues include degraded vertical amplifier response, trigger circuit failures, probe compensation drift, and LCD display degradation affecting waveform visibility.
Infiniium Series High-Performance Analysers
Premium real-time oscilloscopes and protocol analysers for telecommunications, semiconductor characterisation and signal integrity work. Frequent repairs involve reference clock failures causing timebase errors, AFE (analog front-end) component failure, and USB/Ethernet interface faults.
RF and Microwave Signal Analysers
Spectrum and network analysers used in Indian telecom labs, RF manufacturing and wireless testing facilities. Typical faults include attenuator step relay stiction, mixer diode degradation, local oscillator phase noise increase, and firmware corruption affecting frequency calibration.
Handheld Universal Meters and Clamp Meters
Portable digital multimeters and power analysers deployed across Indian industrial sites for field troubleshooting and power quality measurement. Common failures include battery connector oxidation, overload-damaged input circuits, display segment faults, and calibration drift.
Logic Analysers and Protocol Debuggers
8-channel to 16-channel logic analysers used in embedded systems labs and semiconductor test environments across India. Repairs address pod connector intermittency, timing skew calibration errors, and software interface crashes with modern Windows environments.
Power Analysers and Data Acquisition Systems
Three-phase power monitoring and data logging equipment essential for Indian power quality assessment, HVAC systems optimisation and energy audits. Frequent issues include current transformer signal conditioning failures, isolated analog input channel noise, and SD card slot wear.

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 KEYSIGHT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KEYSIGHT equipment arriving at our workshop.
- ✓Oscilloscope display degradation or pixel failure — LCD panel age-related backlight dimming, ribbon cable intermittency between display and motherboard, or LCD driver IC failure after thermal stress. InfiniiVision models show this after 7-8 years of continuous operation in Indian lab environments.
- ✓Timebase or reference clock instability — 10 MHz reference oscillator frequency drift, temperature-compensated crystal degradation, or phase-lock loop (PLL) circuit failure. High ambient temperatures in Indian manufacturing facilities accelerate clock ageing.
- ✓No trigger or unstable trigger behaviour — Trigger circuit amplifier offset voltage drift, comparator hysteresis loss, or coupling capacitor failure in the trigger signal path. Over-voltage transients from poor power distribution in Indian industrial labs can degrade trigger stages.
- ✓Vertical amplifier attenuation or gain error exceeding specs — Precision attenuator potentiometer contact wear, operational amplifier slew rate degradation, or gain-setting resistor network tolerance drift due to temperature cycling in Indian factories.
- ✓RF analyser frequency calibration drift or lockout errors — Oven-controlled oscillator (OCO) servo loop failure, mixing diode non-linearity increase, or local oscillator reference signal corruption. Power supply voltage ripple from unreliable Indian mains can destabilise synthesiser circuits.
- ✓USB or Ethernet interface timeout or device not recognized — USB controller firmware corruption from abrupt power loss, FPGA configuration memory bit-flip, or PHY transceiver ESD damage. Indian manufacturing environments have high ESD risk from ungrounded workbenches.

Frequently Asked Questions — KEYSIGHT Repairs
Do you repair Keysight equipment anywhere in India?+
Yes. Synchronics repairs the full Keysight product range — oscilloscopes, analysers, multimeters, logic analysers and power analysers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore and all tier-2 cities. Repairs are handled at our Vadodara, Gujarat facility with 48-72 hour turnaround for most instruments. We provide calibration certificates compliant with Indian metrology standards.
How do you calibrate Keysight oscilloscopes after repair?+
Synchronics calibrates all Keysight instruments against NIST-traceable standards using precision decade boxes, function generators, and frequency counters. For oscilloscopes, we verify vertical gain accuracy at 1V, 5V and 10V ranges, measure trigger threshold linearity, confirm timebase accuracy to ±5 ppm, and test probe compensation networks. You receive a signed calibration certificate. We maintain 24-month calibration intervals recommended by Keysight.
What is the typical repair cost for Keysight InfiniiVision oscilloscopes?+
Keysight oscilloscope repairs range from Rs 8,000 to Rs 35,000 depending on fault complexity. Display replacement costs Rs 12,000-18,000. Trigger circuit repairs Rs 8,000-12,000. Full analog front-end recalibration Rs 6,000. We provide free fault diagnostics, itemised quotations, and 12 months warranty post-repair. For Indian manufacturers with annual service agreements, we offer 15-20% discounts on repair labour.
Can Synchronics repair Keysight RF analysers with phase noise or spurious performance issues?+
Yes. Keysight RF and microwave analysers require specialist phase-locked loop (PLL) tuning and local oscillator chain calibration. Our engineers have access to Keysight service manuals and phase noise measurement setups. We diagnose mixer non-linearity, recalibrate frequency offset tables, and replace synthesiser modules. Post-repair, we verify phase noise, harmonic suppression, and spurious-free dynamic range. Typical turnaround is 7-10 days for complex RF repairs.
Do you stock Keysight replacement parts or offer genuine Keysight modules?+
Synchronics sources genuine Keysight components and modules directly from authorised distributors in India. Common spares — oscilloscope probes, attenuator modules, trigger ICs, display panels — are stocked. For rare or discontinued modules, we coordinate with Keysight's Indian partners to expedite procurement. We never use counterfeit parts. All components are warrantied and traceable.
How do I send my KEYSIGHT 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 KEYSIGHT 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 KEYSIGHT 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 KEYSIGHT 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.
