It generates a wide, flat, RF noise signal. The NS-1 is popular for testing network components and aligning a building’s coaxial cable network.
The NS-1’s signal is injected into the network at point A. Using a signal receiver, such as a signal level meter (like Applied Instruments' XR-3 or Super Buddy) or spectrum analyzer, the NS-1’s signal is received at point B. The frequency response of the network, between points A and B, is obtained. This measurement allows the user to verify the integrity of the cabling and its associated connections at all frequencies between 1 and 2150 MHz.
