New Carrier-to-Noise Generator with an Integrated Spectrum Analyzer

Noisecom has announced a new CNG-EbNo programmable precision carrier-to-noise (C/N) generator with an integrated spectrum analyzer designed for communication system 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. This new C/N generator with integrated spectrum analyzer solves the problem by leveraging power level measurement capabilities of the spectrum analyzer and generating C/N ratios with that data.

It is a fully automated instrument that sets and maintains a highly accurate ratio between a user-supplied carrier and internally generated additive white Gaussian noise (AWGN) over a wide range of signal power levels and frequencies. This instrument gives system, design and test engineers in cellular, satellite and military communications industries a cost-effective means of obtaining higher yield through automated testing plus increased confidence from repeatable, accurate test results.

These CNG-EbNo series precision generators are frequency and power customizable. Below is a demo of the CNG-EbNo at IMS 2016:
