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
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
