Noisecom's CNG-EbNo Series precision Eb/No Generator

Posted August 17, 2015


Automates and Speeds up Satellite Modem BER vs. Eb/No Testing 

Noisecom, a Wireless Telecom Group company (NYSE: WTT), simplifies Satellite Modem BER vs. Eb/No testing with its family of Programmable Precision Eb/No Generators.

BER is the main indicator of transmission quality in a Satellite communication system and Eb/No is its main driver. Generating the right Eb/No ratio requires precision measurement of the desired signal power and noise power, calculating Eb, energy per bit, using the data rate and No normalized noise in 1 Hz bandwidth. Noisecom's CNG-EbNo, a fully automated precision Eb/No generator, sets a highly accurate ratio between a user-supplied carrier and internally generated noise over a wide range of signal power levels and frequencies. A fully calibrated high dynamic range power meter allows the CNG-EbNo to set the desired Eb/No ratio to within ±0.2 dB. The CNG-EbNo gives system, design, and test engineers in the civilian and military satellite communication industries a cost-effective means of obtaining higher yield through automated testing, plus increased confidence from repeatable, accurate test results. Satellite applications include military communications, SATCOM, L-band, Milstar, Inmarsat and Intelsat. Special configurations can provide improved accuracy. Dual band units as well as custom frequencies and configurations are available.

"We see increased activity in next generation Satellite design and deployment .." said Joe Debold, Executive VP of Sales & Marketing at WTG. "Noisecom has been supplying the satellite and cable modem industries with sophisticated test solutions such as CNG-EbNo for more than two decades.  The increased deployment activity has put pressure on the design, system and test engineers to perform their testing faster but without compromising on accuracy. CNG-EbNo gives them a state of the art test solution for their BER versus Eb/No testing".

From the basic noise diode die to the most sophisticated noise generators Noisecom's noise products have been in use in major laboratories around the world for decades and become the standard for noise generation. The CNG-EbNo series precision Eb/No generators are frequency and power customizable.
