Modern receiver systems often must process very weak signals, but the noise added by system components tends to obscure those very weak signals. Of the parameters involved, noise figure is unique in that it is suitable not only for characterizing the entire system, but also system components such as the preamplifier, mixer and IF amplifier that make up the system. By controlling the noise figure and gain of the system components, the designer directly controls the overall system noise figure. Once the noise figure is known,
the system sensitivity can be easily estimated from the system bandwidth.
Noise figure is often the key parameter that differentiates one system from another, one amplifier from another, and one transistor from another. Such widespread application of noise figure specifications means that highly repeatable and accurate measurements between suppliers and their customers are very important.
The reason for measuring the noise properties of networks is to minimize the problem of noise generated in the amplifiers of receiver systems.
One approach to overcoming noise is to make the weak signal stronger. This can be achieved by increasing the transmitted signal power in the direction of the receiver, or by increasing the amount of power intercepted by the receiving antenna, for example by increasing the aperture of the receiving antenna. Raising antenna gain, which usually means a larger antenna, and increasing transmitter power are ultimately limited by government regulations and by engineering or economic considerations.
The other approach is to minimize the noise generated within the receiver components. Noise measurements are the key to ensuring that the added noise is minimal. Once noise is added to the signals, receiver components can no longer distinguish the noise in the
signal frequency band from legitimate signal fluctuations. The signal and noise are processed together. Subsequently raising
the signal level with gain, for example, will increase the noise level by an equal amount.
DESCRIPTION AND OPERATION
The N8973A is a high-performance noise figure analyzer designed to make noise figure measurements fast, accurate and repeatable.
With the N8973A’s easy-to-use features, you can set up complex measurements simply and in a repeatable way, and get reliable results you can trust.
The N8973A offers simultaneous noise figure and gain measurements, with the ability to view, print and save the data/display in multiple formats.
The N8973A can also characterize frequency-translating amplifiers and devices, including control over a dedicated second GPIB LO.
The N8973A offers increased measurement accuracy and faster measurement speed, as well as six user-selectable measurement bandwidths.
