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.
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.
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.
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.
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.
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
Mission-critical emc / emi test system repair across the sectors where instrument downtime is unacceptable.
MIL-STD-461 / DO-160 chambers, BCI probe sets, and immunity systems — repaired with documentation that survives DCMA scrutiny.
EMI receivers and immunity generators for FCC Part 15, CE, and carrier acceptance — fast turnaround when chamber time is booked.
IEC 61000-6 series compliance gear, surge generators, and conducted-immunity rigs for factory-floor PLC and drive testing.
CISPR 25 antennas, BCI probes, and ALSE chambers — repaired and re-accredited for ISO 11452 and ECE R10 audit work.
Inverter EMC characterization gear, current probes, and high-power surge generators for PV, motor-drive, and EV charger labs.
IEC 60601-1-2 chambers, immunity generators, and ESD guns — repaired with FDA QSR-aligned documentation.
Reference receivers, BCI probes, antennas, and LISN sets returned in spec so the lab’s ISO/IEC 17025 accreditation isn’t put at risk.
Wi-Fi 6E/7, BLE, Zigbee, LoRa test instruments — receivers and signal generators repaired for RF certification labs.
Every Techmaster repair includes a post-repair calibration sticker on the instrument. Choose the depth of repair and the documentation level that matches your audit and operational needs.
