The NC1000 Series amplified noise modules produce AWGN as high as +13 dBm, and have bandwidths up to 18 GHz. The high power modules are designed to test noise immunity for Cable TV equipment, secure communication channels, and military jamming systems. The lower power modules, <= 0 dBm, are random jitter sources for many applications including, PCIexpress, Infiniband, and 10 GigE. The Bandwidth, output power, and flatness can be modified for specific applications. A newly developed TTL controlled attenuation feature is also available.
