The Y-factor method simplifies noise figure measurements by allowing the use of variable attenuators in place of a calibrated power meter. In addition to defining the Y factor, we will discuss noise source uncertainty and fixturing losses that can introduce errors in your noise figure measurements.

The Y-factor method is a widely used technique for measuring the gain and noise figure (NF) of RF components. This article will help you understand the differences between the insertion gain and the available gain, while avoiding potentially significant errors when measuring the noise figure.

This project demonstrates the design and operation of a root-mean-squared (RMS) detector for inclusion in a wideband voltmeter. The RMS detector is useful for measuring certain signal types, including noise, since it provides an indication of the energy in a signal.
