Noise modules have bandwidths up to 10 GHz
By Staff -- Test & Measurement World, 9/1/2007
Wireless Telecom has added two modules to its family of amplified noise sources: the Noise Com NC1127A and NC1128A. With their white Gaussian noise distribution, the modules can be used as random jitter sources for many applications, including PCI Express, Infiniband, 10 GigE, and IEEE 802.3ap backplane Ethernet testing.
The NC1127A operates from 10 MHz to 5 GHz and provides output power of –20 dBm at –117 dBm/Hz and output flatness of ±2.5 dB. The higher-frequency NC1128A covers a range of 10 MHz to 10 GHz and provides output power of –17 dBm at –117 dBm/Hz and output flatness of ±2.5 dB. Both devices operate over a temperature range of –35°C to +100°C.
The output of each noise source connects to an RF amplifier that boosts power to the desired output. NC1000 modules can be used for a wide variety of applications that require the injection of noise at high levels, including CATV equipment, secure communication channels, and military jamming systems.
