Attenuators Set of 5 Power Meter

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to the calibration of RF Attenuators between 1 and 26.5 GHz.

This ILC/PT contains a set of 5 attenuators; each is a 20 dB, 3.5 mm device.

Participants will utilize their practices to perform 60 separate attenuation measurements, as they connect each device, perform dB Loss measurement at a predetermined four frequencies, remove the device, rotate the device per instructions, reconnect, perform measurements at the same four frequencies, remove and rotate the device again and reconnect to perform a third set of measurements. The average of the three measurements at each frequency is reported, and the entire process is repeated with the remaining 4 attenuators.

RF Sensor/Meter

The purpose of this ILC/PT is to give organizations an opportunity to demonstrate their proficiency (e.g., use of appropriate equipment, procedures, ability to follow instructions) in measuring RF Power Meter Reference and Power Sensor Cal Factors. 

By participating, participants will demonstrate technical competence for the measurements associated with these parameters. Associated reported uncertainties of the measurement made will also be evaluated as part of this ILC/PT. Participants are required to make a measurement of the artifact parameters within their stated capabilities.
