Precision C/N Ratio Generation at Specific Carrier Frequencies Enables New Testing Capabilities for Multi-Signal Data Streams in Satellite Communications
Noisecom, a Wireless Telecom Group company, announces a new CNG-EbNo programmable precision carrier-to-noise (C/N) generator with an integrated spectrum analyzer designed for communication systems data streams that include multiple carriers in the frequency band. This new CNG-EbNo allows system designers and test engineers to isolate and characterize a specific frequency in the input data stream, accurately measure the power of the carrier at that frequency and generate a precise C/N ratio. Traditionally a C/N ratio generator takes power level measurements across the entire frequency band and generates a C/N ratio based on the average power measured across the band. This is effective with a single carrier or frequency of interest but once multiple data streams are introduced this method is inadequate.
