Abstract :
Absolute measurements of noise-figures in the UHF range are described, using hot and cold thermal sources as standards. It was found that the noise temperature of the T-5 6 watt fluorescent tube is 16.1 kO.6 db above k T delta v. Noise diodes were found to be in error at these frequencies by approximately 1 db.
