ANA Measurement Results on the ARFTG Traveling Experiment

The Automatic Rf Techniques Group (ARFTG) Executive Committee has assembled two traveling measurement assessment kits. Each of these kits consists of: l-dB, 20-dB, 40-dB, and 60-dB attenuators; a 50-ohm termination; a 10-centimeter air line; 1.2-VSWR and 2.0-VSWR mismatched terminations; and a short circuit termination. These devices are equipped with precision 7-mm coaxial connectors. The traveling kits are being circulated among measurement laboratories that wish to assess their ability to measure reflection coefficient, attenuation, and phase shift from 300 MHz to 17 GHz. The results obtained on ten different automated measurement systems are presented.
