Precision Eb/No Generators for BER Testing to 44 GHz

With the continually increasing complexity of digital modulation techniques employed in wireless and satellite communications systems, instruments that accurately generate and maintain a set level of bit energy-to-noise density ratio (E b /N o ) have become valued tools in optimizing bit-error rate (BER) performance. These instruments have been...
