RF & Microwave Calibration

Our Capabilities

Marsh Metrology offers ISO/IEC 17025:2017 accredited calibrations for radiofrequency and microwave tools and equipment. We are accredited to calibrate equipment up to 26.5 GHz. We have over 30 years of experience in metrology and calibration. Our experienced metrologists can identify, test, calibrate, repair and certify radiofrequency or microwave equipment to an ISO 17025:2017 accredited standard.1

We are able to deliver RF calibration services at our location, in Burlington ON, or at your facility, either integrated into your process, or using our state of the art RF/Microwave equipped mobile calibration lab. 

We can provide certified calibration and analysis services for preproduction designed sub-Assemblies, RF filters, amplifiers, attenuators and much more. This is based on our automated & semi-automated systems performance and GPS frequency standard.

Our Measuring receiver delivers the accuracy and resolution of a high-performance power meter at frequencies from 150 kHz to 1.3 GHz (50 MHz to 26.5 GHz with the 11793A microwave converter) and levels from +30 dBm to -127 dBm.

It accurately also measures AM, FM and ØM, including residuals and incidentals.

Measuring receiver, with the 11792A, counts RF signals to 26.5 GHz with 10 Hz resolution and excellent long-term frequency stability with following important included options in our system:

  • High Stability Time Base
  • High Selectivity

  • RF input frequency range 0.05 -26.5 GHz with High Stability LO & MW Mixer
  • RF operating level: 12 mV RMS to 7 V RMS
  • Tuned RF level frequency range: 2.5 MHz to 1300 MHz
  • Tuned RF power range: -127 dBm to 0 dBm
  • Input impedance: 50 ohms
  • FM rates: 20 Hz to 200 kHz
  • FM deviations: to 400 kHz
  • Phase modulation carrier frequency: 10 MHz to 1300 MHz
  • Phase modulation rates: 200 Hz to 20 kHz
  • Phase modulation deviation: to 400 radians
  • Phase modulation deviation resolution: 0.001 radian
  • AM rates: 20 Hz to 100 kHz

Convenient Service Options

We offer a wide array of calibration services, offered in a convenient way. 

On Site/In-Situ Calibration

We can perform on site and in process calibrations, which are ISO/IEC 17025:2017 accredited and traceable to the National Standards, complete with calibration reports and stickers.

Calibration Management

Our calibration management service provides you with in time notifications of instruments that are soon due for calibration. Our customer Portal provides you access to manage your assets as well as our warehouse for equipment storage and fast calibration retrieval

Diagnostic & Repair

Our calibration service offers equipment testing. Should your equipment fail calibration, we can repair and assist with the purchase and calibration of a replacement, in order to minimize your disruption.
