EMC / EMI Test System Repair
Techmaster Electronics provides factory-trained repair of EMC and EMI test instruments, Rohde & Schwarz ESW / ESR / ESL receivers, Keysight N9038A MXE, Schaffner / EM Test surge and burst generators, EMC Partner ESD guns, and Schwarzbeck antennas. Every repair returns with ISO/IEC 17025 accredited post-repair calibration so the instrument is immediately audit-ready for FCC, CISPR, and IEC 61000 work.
Equipment We Repair
EMC / EMI test labs depend on instruments that hold their accreditation between audits. Every repaired unit is verified against NIST-traceable standards and shipped with a certificate referencing ANAB Cert AC-1736.
EMI Receivers
Rohde & Schwarz ESW / ESR / ESL, Keysight MXE / PXA, RF deck repair, preselector tuning, reference-oscillator service, and post-repair traceable cal across the CISPR / MIL-STD bands.
RF Immunity Generators
Schaffner NSG, EM Test EMC Compact, AR / IFI / Empower amplifiers, power-amp rebuild, output-stage refurbishment, control-board repair, and full IEC 61000-4-3 / -4-6 verification.
BCI Probes & Current Clamps
Bulk Current Injection probes (FCC, ETS-Lindgren), EMI current clamps (R&S MDS, EMCO 91550), and LISN sets, toroid replacement, insertion-loss re-characterization, and post-repair calibration.
EMC Antennas
Biconical, log-periodic, horn (DRH), and bilog antennas (Schwarzbeck, ETS-Lindgren, R&S, EMCO), element / balun repair, connector refurbishment, and antenna-factor calibration on our 3 m or 10 m site.
Also repaired: Surge Generators · Burst / EFT Generators · ESD Simulators / Guns · LISN (Line Impedance Stabilization Networks) · CDN (Coupling / Decoupling Networks) · Field Probes · RF Power Amplifiers · TEM / GTEM Cells · Conducted Immunity Test Sets

Frequently Asked Questions
Common questions about emc / emi test system repair at Techmaster Electronics.
What is the typical turnaround for EMC / EMI test equipment repair?
Standard repair turnaround is 7–10 business days from receipt, including post-repair ISO/IEC 17025 calibration verification. Antenna refurbishment with full antenna-factor re-characterization may require 10–15 business days. Expedited service is available for production-line and chamber-downtime cases.
Will the repaired instrument still meet CISPR / MIL-STD / IEC 61000 accreditation requirements?
Yes. Every repaired EMC / EMI instrument is verified against NIST-traceable standards before it ships back. Repairs include an ISO/IEC 17025 accredited calibration certificate against ANAB Cert AC-1736, so the instrument is immediately usable for accredited test reports.
Do you repair the RF power amplifiers used in immunity testing?
Yes. We repair AR, IFI, Empower, Bonn, and Prana high-power amplifiers, output-stage rework, power-meter / forward-power detector replacement, and full power-output verification across the rated band.
Do you re-characterize EMC antenna factors after repair?
Yes. After any element, balun, or connector refurbishment on a biconical, log-periodic, horn, or bilog antenna, we run a full antenna-factor calibration on our 3 m or 10 m site. The cert ships with factors at the standard CISPR / MIL-STD frequencies.
What if the EMI receiver can’t be brought back into compliance?
We provide a written diagnosis and credit the evaluation fee toward a refurbished or rental replacement from our Sales & Rentals inventory. You only pay the evaluation fee on unrepairable units.
Which Techmaster locations perform EMC / EMI repair?
EMC / EMI repair is performed at our Vista CA, Santa Clara CA, Orlando FL, and San Antonio TX laboratories. Free local pickup is available in Silicon Valley, Southern California, and Orlando.
