Repair and Calibration of Amplifier Research Branded RF Test Equipment

repair and calibration of Amplifier Research (AR) RF test equipment used in EMC, RF, microwave and laboratory testing.
We provide repair and calibration of Amplifier Research (AR) RF test equipment used in EMC, RF, microwave and laboratory testing. Our service covers a range of legacy and current-generation AR equipment, including RF power amplifiers, microwave amplifiers, field probes, antennas and integrated EMC test systems. If your Amplifier Research equipment has low RF output, unstable performance, fault indications, overheating or calibration concerns, contact us with the model number and serial number for an assessment and quotation.

Amplifier Research RF Equipment Repair and Calibration

Amplifier Research equipment is widely used in RF and EMC test laboratories. RF power amplifiers are commonly used to generate the field strength required for radiated and conducted immunity testing, while associated antennas, field probes, couplers and measurement equipment provide the necessary test and measurement functions.

We can assess and service equipment including:

  • AR 100A250A RF power amplifier
  • AR 25A250B RF power amplifier
  • AR 100W1000A RF power amplifier
  • AR 250W1000A RF power amplifier
  • AR 50S1G6 microwave RF power amplifier
  • AR 100L broadband RF power amplifier
  • AR AT4000A log-periodic antenna
  • AR FL8200/Kit field probe
  • AR CI00402 conducted immunity test system
  • AR emcware® EMC test automation software

Common Repairs Performed by Niche RF

Niche RF Offers a variety of Repairs, Maintainance and Calibration of products from “Amplifier Research” Brand (including legacy products currently out of production).

Model numbers should be confirmed from the equipment nameplate before service, repair or calibration. This is particularly important for older Amplifier Research equipment and models that have subsequently been replaced or re-designated.
