GENRAD Equipment We Repair — By Category
GENRAD Product Lines We Repair
Our engineers are trained on the full GENRAD product range. Below are the major product families we service.
Impedance Bridges (GR-1620 / GR-1621 / GR-1650 Series)
Precision RLC impedance bridges used for component characterisation in electronics manufacturing and calibration labs. Common faults include oscillator instability, detector circuit failures, and decade switch contact degradation affecting measurement accuracy.
Capacitance Meters (GR-1621 / GR-1684 Series)
Automated capacitance measurement instruments for production testing and QC labs. Typical issues involve display panel failures, oscillator frequency drift, and measurement circuit non-linearity requiring recalibration.
RF Signal Generators (GR-1310 / GR-1311 Series)
Precision RF signal sources for telecommunications and EMC testing. Common failures include frequency synthesiser lockup, attenuator circuit faults, and output amplifier degradation affecting signal purity.
Decade Resistance/Capacitance Boxes (GR-100 / GR-101 Series)
Precision resistance and capacitance decade boxes for circuit simulation and calibration work. Failure modes include corroded decade switch contacts, thermal drift in resistor networks, and capacitor leakage affecting dial accuracy.
Vector Voltmeters (GR-1930 Series)
Precision AC voltmeters for telecommunications network analysis. Common problems include detector diode non-linearity, reference oscillator instability, and phase measurement errors requiring full recalibration.
Dielectric Loss Bridges (GR-1620 Variants)
Specialised bridges for measuring dielectric properties of capacitors and insulation materials. Issues typically involve bridge balance circuit degradation, null detector sensitivity loss, and capacitive coupling problems.

Common GENRAD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENRAD equipment arriving at our workshop.
- ✓Oscillator frequency drift and instability — GenRad precision instruments rely on stable crystal oscillators and LC tank circuits. Age-related capacitor degradation, temperature coefficient drift, and printed circuit board (PCB) contamination from moisture ingress cause frequency instability, leading to measurement errors and failed null detection in bridges.
- ✓Decade switch contact corrosion and intermittent resistance — GenRad decade boxes use multi-position rotary switches with precious metal contacts. Corrosion from atmospheric exposure, acid flux residue, or inadequate shielding creates contact resistance variation and intermittent open circuits, making decade setting unreliable.
- ✓Display panel and meter movement failures — Older GenRad instruments feature mechanical moving-coil meters and incandescent display backlighting. Meter coil burnout from transient overcurrent, mechanical bearing wear, and bulb burnout are common. Capacitor leakage in driver circuits adds measurement offset.
- ✓Measurement circuit non-linearity and accuracy loss — GenRad precision instruments depend on stable resistor networks, diode linearity, and transformer coupling. Component aging, thermal drift of metal-film resistors, and diode junction degradation introduce measurement errors. Transformers suffer winding insulation breakdown.
- ✓Detector null sensitivity degradation — GenRad bridges use precision null detectors (mechanical galvanometers or diode detectors) to indicate circuit balance. Galvanometer coil fatigue, diode junction leakage, and amplifier circuit drift reduce sensitivity, making it impossible to achieve sharp null and measure accurately.
- ✓RF output attenuator step errors and discontinuity — GenRad RF signal generators employ precision resistive attenuators with stepped 10 dB, 1 dB, and 0.1 dB controls. Resistor tolerance drift, corroded switch contacts in attenuator ladder networks, and output impedance mismatch cause step discontinuity and non-linear attenuation.

Frequently Asked Questions — GENRAD Repairs
Do you repair GenRad equipment anywhere in India?+
Yes. Synchronics repairs the complete range of GenRad precision measurement instruments — impedance bridges, capacitance meters, RF signal generators, decade boxes, and vector voltmeters — across India. We offer PAN India doorstep pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other cities. All repairs are processed at our ISO 9001-certified facility in Vadodara, Gujarat, with NABL-traceable calibration.
What is GenRad calibration certification and why does it matter?+
GenRad instruments are precision measurement tools — their value lies in measurement accuracy, not just functionality. Synchronics provides NABL-traceable calibration certificates documenting measurement uncertainty and traceability to SI standards. This certification is essential for quality audits, regulatory compliance (ISO/IEC 17025), and liability protection in Indian manufacturing and defence sectors. Without certified calibration, GenRad equipment cannot be legally used for QC or compliance testing.
How long does GenRad repair and calibration typically take?+
Turnaround depends on fault complexity. Simple faults (oscillator recalibration, decade switch cleaning) take 5-7 working days. Component replacement (capacitors, diodes, resistor networks) takes 10-14 days. Complex faults (meter movement rebuild, transformer rewinding) take 3-4 weeks. We expedite critical repairs on request. Emergency repairs within 48 hours are available for telecommunications and defence customers at premium rates.
Can Synchronics repair old GenRad instruments from the 1970s and 1980s?+
Absolutely. GenRad's legendary build quality means many 1970s-80s instruments remain functional. Our 180+ engineers have restored classic GR-1620, GR-1650, GR-1310, and GR-100 series units for Indian government labs and research institutes. Parts obsolescence is our main challenge — for aged resistor networks and transformers, we source compatible military-grade replacements or hand-craft matched units. Restoration timelines extend to 6-8 weeks for heavily degraded instruments, but we achieve >95% restoration success.
Why should I choose Synchronics over GenRad factory service for repairs?+
GenRad discontinued factory service in India decades ago. Synchronics is the only NABL-certified independent repair centre for GenRad instruments across India with expertise in precision metrology. We offer faster turnaround (5-21 days vs. 4-6 weeks for overseas factory service), lower costs (40-60% savings vs. USA factory rates), local spare parts inventory, and pickup-delivery service. For Indian manufacturing, telecom, and defence customers, local expertise and rapid turnaround are essential competitive advantages.
How do I send my GENRAD 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 GENRAD 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 GENRAD 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 GENRAD 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.
