Impact of Receiver Bandwidth and Nonlinearity on Noise Measurement Methods [Application Note]


The article has dealt with problems of noise measurement located on the receiver side. The influence of noise bandwidth B and receiver gain GREC on the measured power level FNwas discussed. The digital realization of B enables a revival of the signal generator method. The need for a calibrated noise generator is eliminated and a VNA can be used a receiver… (More)
