Calibrated noise sources cover frequencies from 10 kHz to 18 GHz

February 07, 2018 // By Julien Happich
A line of calibrated noise sources from Fairview Microwaveare designed to be used as a precision reference source to measure system level noise figure. They can also be used as a source for bit error rate (BER) testing for SATCOM and digital radio systems and as a source for Gaussian jitter for testing of optoelectronic devices. 

Ten new calibrated noise source models cover frequency bands from 10 kHz to 18 GHz with output ENR levels ranging from 15 dB to 30 dB and typical VSWR levels as low as 1.25:1. Depending on the model, calibrated frequency points are at 10 MHz, 100 MHz, 1000 MHz, 2000 MHz and 1 GHz steps. The temperature coefficient of these noise sources is < 0.01 dB/°C and noise output variation is < 0.1 dB/%V.

Designs incorporate 50 Ohm hybrid circuit board assemblies that use packaged noise diodes and other discrete components which are tuned for optimum performance. Assemblies are enclosed in rugged metal packages that use an SMA female output connector and, depending on the model, the DC connector is either solder pin or BNC female.
