Noise figure meters are specialty equipment used to determine how much noise is added to a signal between the input and output of a system. In order to get accurate measurements, special calibration procedures are needed that, without the availability of a piece of test equipment designed for the task, can be very involved. Fortunately, there are companies that have done the hard work, and all you have to do it push buttons.
A noise generator is an item that might seem to be a no-brainer, but when calibrated measurements are needed to specification publications, it is best to leave it to the pros.
