产品总览

The CNG-EbNo is a fully automated instrument that sets and maintains a highly accurate ratio between a user-supplied carrier and internally generated AWGN noise, over a wide range of signal power levels and frequencies.

The CNG-EbNo gives system, design, and test engineers in the cellular/PCS, satellite and military communication industries a cost-effective means of obtaining higher yield through automated testing, plus increased confidence from repeatable, accurate test results.

Key Features

C/N carrier to noise ratio

C/I carrier to interferer ration

C/No carrier to noise density ratio

Eb/No bit energy to noise density ratio

Custom configurations

6.25" color TFT touch screen

Accuracy of 0.2 dB RSS

Bit Rates from 1 bps to 1 Gbs

Variable Output Power from -55 dBm to +5 dBm

Benefits
Multiple Operating Modes	The CNG-EbNo provides five operating modes: carrier-to-noise (C/N), carrier-to-noise density (C/N₀ ), bit energy-to-noise density (Eb/N₀ ), carrier-to-interferer (C/I), and power meter. The instrument can also be used as a precision noise generator.
Custom Configurations	The CNG-EbNo is available in a variety of configurations to meet your specific testing needs. Applications include: military communications WCDMA SATCOM NASA TDRSS CableTV HDTV IS-95 CDMA TSMA UMTS GPRS L-band modems Milstar Inmarsat Intelsat General Purpose.
Direct Display of Eb/No, C/N, C/I, or C/No	The 6.25” color TFT touch screen provides simultaneous readout of all significant input and output signal levels relating to the chosen operating mode, including carrier-to-noise ratios.
Accuracy of 0.2 dB RSS	A special, large-dynamic-range power meter measures both the signal and the noise, which allows the CNG-EbNo to set the desired ration to within ±0.2 dB. Special configurations can provide improved accuracy.
Bit Rate Entry of 1 bps to 999 Mbps and above	In bit energy-to-noise density testing (Eb/No ), the instrument automatically calculates noise density based on the user specified bit rate.
Variable Output Power	Output power is user-specified and can be set within the range of -55 dBm to +5 dBm.
True RMS Power Meter	The digital power meter is custom designed to cover the frequency range of the particular instrument. It can measure signals and noise accurately with Gaussian Noise crest factors up to 18 db.
Direct Testing at both RF and Microwave Frequencies	In configurations that cover two separate frequency ranges, measurements can be made directly without the need for special conversion circuitry.
