Annual recalibration is important to ensure repeatable and reliable data. At our facility, we calibrate our own antennas, as well as, most other brand antennas in accordance with ARP, ANSI, and IEEE specifications. Calibration data can be provided for 1, 3 and 10 meter distances up to 40 GHz. All Testing Equipment is NIST Traceable and comes with a calibration Certificate per ANSI/NCSL Z540 conforming to an internal quality system based on ISO 17025.
To meet with your exacting standards, we also comply with the following standards and practices:
- ISO/IEC 17025
- ANSI/NCSL Z540-1
- MIL-STD 45662A
To ensure repeatable and reliable antenna measurements, our measurment test equipment is recalibrated and traceable to NIST. This traceable test equipment results in a good uncertainty to the true value being measured.
Calibration Data is maintaned in a secure location as well as backed up to an offsite location for a minimum of 5 years
To ensure an acurate and quick calibration service, please specify what standard to perform the calibration to. Below is a list of the calibration standards that we can calibrate to:
ANSI C63.5 - American National Standard for Electromagnetic Compatibility—Radiated Emission Measurements in Electromagnetic Interference (EMI) Control—Calibration of Antennas (9 kHz to 40 GHz)
SAE ARP-958 - Electromagnetic Interference Measurement Antennas—Standard Calibration Method
IEEE 291 - IEEE Standard Methods for measuring Electromagnetic Field Strength of Sinusoidal Continuos Waves, 30 Hz to 30 GHz
RCTA DO-160 - Environmental Conditions and Test Procedures for Airborne Equipment
CISPR 16 - Specification for Radio Disturbance and Immunity Measuring Apparatus and Methods
Other standard and calibration techniques are available upon request.
