Vector network analysers for component characterization and transmission line testing. Frequent faults include cal kit connector wear, VNA port isolation degradation, and firmware boot failures affecting calibration memory.
MG3710A / MG3720A RF Signal Generators
Waveform and vector signal generators for device testing and signal simulation. Repair-critical issues include YIG oscillator frequency instability, modulation path linearity loss, and reference clock phase noise degradation.
MT8821C / MT8820C Radio Communication Test Sets
Multi-standard test instruments for 2G/3G/4G/5G handset and base station validation. Common failures: RF transceiver saturation, baseband processor thermal shutdown, and firmware corruption on field software updates.
BertWave MP1800A Error Rate Test Sets
High-speed digital signal quality analysers for optical and RF transmission testing. Typical repairs involve jitter measurement module calibration drift, clock recovery phase-lock failures, and triggering system errors.
Optical Power Meters and Light Sources
Wavelength-specific optical measurement instruments for fibre network installation and fault diagnosis. Common issues: photodiode sensitivity drift, wavelength reference calibration loss, and laser output power decay requiring tube replacement.

Common ANRITSU Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ANRITSU equipment arriving at our workshop.
- ✓Spectrum analyser frequency readout drift beyond spec — Anritsu spectrum analysers use YIG oscillators and phase-lock loops sensitive to thermal cycling. Frequency reference aging and PLL component capacitor drift cause ±1-5 MHz error in high-frequency bands, especially in field-deployed units exposed to temperature swings.
- ✓Network analyser Cal Kit connector repeatability errors — Anritsu network analysers store calibration coefficients tied to specific cal kit connectors. Repeated mating cycles wear 3.5mm, N-type, or 7mm connectors, causing contact resistance variation and calibration data corruption. Environmental contamination accelerates wear.
- ✓RF signal generator modulation path clipping and distortion — Anritsu MG37xx generators use hybrid analogue-digital modulation chains. Thermal aging of RF mixer diodes, baseband filter capacitor loss, and DAC output buffer saturation introduce harmonics and reduce modulation accuracy below -40 dBc, failing vector signal quality tests.
- ✓MT8821C baseband processor thermal shutdown during test — Anritsu MT8821C radio test sets run intensive DSP algorithms in compact chassis. Dust buildup in intake filters, thermal paste degradation between processor and heatsink, and fan bearing wear reduce cooling effectiveness, causing unexpected shutdowns at 65-70°C.
- ✓Optical power meter photodiode sensitivity drop — Anritsu optical power meters use silicon and germanium photodiodes mounted behind optical filters. Prolonged UV exposure, dust contamination on lenses, and photodiode aging reduce responsivity by 5-15%, causing under-reporting of power levels by 0.5-1.5 dB.
- ✓Firmware boot loop and calibration data loss after update — Field firmware updates for Anritsu instruments can fail if power interrupted, corrupting bootloader or calibration Flash memory sectors. Recovered units boot to safe mode but lose frequency calibration and filter coefficients, rendering field measurement unreliable.

Frequently Asked Questions — ANRITSU Repairs
Do you repair Anritsu equipment anywhere in India?+
Yes. Synchronics repairs the full Anritsu product range - spectrum analysers, network analysers, RF signal generators, and radio communication test sets - across all of India. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and every other major city. All repairs are performed at our certified facility in Vadodara, Gujarat.
What is Anritsu spectrum analyser calibration and why does it matter?+
Anritsu spectrum analysers measure RF power levels, frequency accuracy, and modulation quality. Calibration verifies that internal reference oscillators, attenuators, and RF paths are within published accuracy specs. Without recalibration every 12-24 months, measurement errors accumulate - especially in 5G and defence testing where ±0.1 dB accuracy is critical. Synchronics recalibrates using traceable standards and issues NIST-linked certificates.
Can Synchronics repair Anritsu network analysers with mechanical connector damage?+
Yes. Anritsu network analyser RF ports (3.5mm, N-type, 7mm) are repairable if connectors are damaged. We replace worn connectors with Anritsu-certified parts, restore port isolation, perform full two-port calibration with new cal kits, and re-enter calibration coefficients. Port replacement typically takes 5-7 days depending on connector type availability.
How do I know if my Anritsu MT8821C test set needs repair?+
Common warning signs: unexpected thermal shutdown during long test sequences, measurement results outside historical range, failed self-test diagnostics on startup, or no response to control commands. Synchronics can perform remote diagnostic via serial console or accept in-lab evaluation. Indian telecom and defence labs often trust us for same-week turnaround on critical MT8821C issues.
Does Synchronics provide Anritsu firmware updates and software support?+
Yes. Synchronics manages Anritsu firmware updates, security patches, and measurement software re-licensing. We maintain licenses for Anritsu modular software (baseband options, standards modules, analysis packages) and can deploy updates in your lab or on-site. We also troubleshoot software-related measurement errors and recalibration issues post-update.
How do I send my ANRITSU 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 ANRITSU 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 ANRITSU 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 ANRITSU 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.
