| | | Description: Micronetics CNG DTV Series of Noise Industrial generators are specifically designed for IF loop back testing, such as that called out in ATSCa80. The CNG DTV provides calibrated, accurate C/N ratios for generating BER performance of DTV modems. t True Gaussian nosie for accurate tests agains BER curves based on Gaussian PDF t Self calibration for accurate S/N ratios t Field calibration feature reduces downtime and cost of ownership | | |
