GENERAL RADIO Product Lines We Repair
Our engineers are trained on the full GENERAL RADIO product range. Below are the major product families we service.
General Radio 1602 / 1608 RF Signal Generator Series
Precision RF signal generators delivering stable outputs from 10 kHz to 1 GHz. Common issues include oscillator drift, attenuator accuracy loss, and modulation circuit failures in older units requiring recalibration and component replacement.
General Radio 1659 Impedance Bridge Series
Precision LCR and impedance measurement bridges used in component testing and production verification. Failures typically involve detector amplifier degradation, oscillator frequency drift, and bridge balance potentiometer wear requiring full recalibration.
General Radio Decade Box and Resistor Networks
Precision decade resistance, capacitance, and inductance boxes for lab standards and equipment calibration. Common faults include contact oxidation in rotary switches, capacitor leakage, and wirewound resistor open circuits affecting measurement accuracy.
General Radio Crystal Oscillators and Frequency Standards
Temperature-compensated and oven-controlled oscillators providing frequency references for test equipment and telecom systems. Repair involves crystal retuning, oven controller calibration, and thermal sensor replacement to restore frequency stability.
General Radio Audio and Low-Frequency Oscillators
Precision oscillators covering audio frequencies (10 Hz to 100 kHz) used in acoustic testing, vibration analysis, and component characterization. Failures include phase-shift network component aging and amplifier stage distortion requiring selective replacement.

Common GENERAL RADIO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENERAL RADIO equipment arriving at our workshop.
- ✓RF Signal Generator Oscillator Frequency Drift — Aging capacitors in LC oscillator tank circuits and thermal stability loss over decades of operation. Temperature compensation networks degrade causing frequency shift outside specification (typically ±5 ppm to ±50 ppm depending on model).
- ✓Impedance Bridge Detector Amplifier Distortion — Input coupling capacitor leakage and vacuum tube cathode emission decline in older 1659 series models. This causes reduced detector sensitivity and increased noise floor, making balance point detection difficult during impedance measurements.
- ✓Decade Box Rotary Switch Contact Failure — Oxidation and corrosion of silver or gold contacts on multi-position wafer switches in 901-C and 902-C series, especially in humid Indian environments. Contact resistance increases dramatically (ohms to kilohms), introducing measurement error and intermittent operation.
- ✓Crystal Oscillator Frequency Instability and Aging — Quartz crystal frequency drift due to aging, contamination inside sealed enclosures, and oven heater element degradation in TCXO and OCXO units. Drift rates accelerate with time, losing ±1 ppm to ±10 ppm specification.
- ✓RF Attenuator Accuracy Loss and Non-Linearity — Aging of precision film resistor networks in 1602 and 1608 series attenuators. Resistor values drift due to humidity, temperature cycling, and carbon film degradation, causing attenuation errors of 0.5 dB to several dB at high frequencies.
- ✓Audio Oscillator Phase-Shift Network Capacitor Failure — Electrolytic capacitors in phase-shift networks (1160, 1161 series) dry out and lose capacitance, causing distortion, frequency instability, and waveform degradation. Output becomes non-sinusoidal at low and mid audio frequencies.

How do you handle calibration and certification for General Radio measurement instruments?+
All General Radio signal generators, impedance bridges, and oscillators are calibrated to original factory specifications using precision test equipment. Synchronics maintains traceability to national standards. We provide detailed calibration certificates with frequency response plots, attenuator accuracy data, and impedance bridge balance readings, essential for ISO and quality certifications in Indian manufacturing.
Can you repair vintage General Radio 1602 and 1608 series RF generators still used in Indian labs?+
Absolutely. The 1602 and 1608 series are legendary and many units operate in Indian research institutions and telecom labs. Synchronics specializes in restoring these generators - replacing aged capacitors, recalibrating oscillators, repairing attenuators, and restoring output level accuracy. We handle vacuum tube and solid-state versions with equal expertise.
What is the typical turnaround time for General Radio equipment repair?+
Standard repairs take 5-10 working days. Complex oscillator calibrations and multi-circuit failures may take 15-20 days. Rush services available. Upon receipt, we provide diagnostic assessment and cost estimate within 2 days. Synchronics prioritizes Indian manufacturing plants and research labs requiring quick equipment restoration.
Do you stock spare parts for General Radio impedance bridges and signal generators?+
Yes. Synchronics maintains inventory of common replacement components - capacitors, resistor networks, rotary switches, vacuum tubes, and crystal oscillators compatible with General Radio 1659, 1602, 1608, and decade box series. For obsolete components, we identify modern equivalents tested for compatibility. Lead times typically 2-5 days for parts-in-stock repairs.
How do I send my GENERAL RADIO 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 GENERAL RADIO 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 GENERAL RADIO 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 GENERAL RADIO 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.
