NoiseEb/NoGenerators

Carrier to Noise generator sets

Micronetics' CNG instruments are designed to automatically add noise toa signal to a precise settable power ratio for testing bit error rate (BER)and other parameters. The quality of these tests are only as good as the accuracy of the signal to noise ratio. This signal to noise ratio is oftenexpressed as Carrier:Noise (C/N) or in digital modulation terms, bit ener-gy:noise density (Eb/N
). In this data sheet for purposes of discussion,Eb/N
encompasses all ratio modes that include C/N and C/N
.Micronetics CNG series instruments are designed to very accurately set a signal to noise power ratio overa wide dynamic range of noiseand signal powers while offeringlong term stability and repeatabil-ity. This is accomplished by using high quality RF componen-try, built-in calibration routines, acomplex signal power measure-ment system and sophisticatedsoftware algorithms to pull it all together.
