The Noisecom UFX7000B broadband AWGN noise generator has a powerful single board computer with flexible architecture used to create complex custom noise signals for advanced test systems. This versatile platform allows the user to meet their most challenging design requirements. Precision components provide high output power with superior flatness, and the flexible computer architecture allows control of multiple attenuators, switches, and filter banks.
The standard RF configuration includes a broadband noise source and noise path attenuator with a maximum attenuation range of 127 dB in 0.1 dB steps. Additional attenuation ranges, and step sizes are available. Optional filters can be specified in any combination of low pass, high pass, band pass, or band reject. Combined with advanced switching circuitry, the designer can create many different path combinations. The signal output connectors can be located on the front, or rear panel to provide convenient customer access on the bench, or in a rack system. An optional signal combiner, and signal attenuator allow independent control of the noise & signal paths to vary SNR while BER testing.
The unit has a 7-inch touch-screen display, mouse, and keyboard for manual control, or standard Ethernet for ATE remote control. Optional IEEE 488.2 GPIB and RS232 remote interfaces are also available. If there are additional requirements for your noise application, please contact the factory for more information about custom designs.
