60. G Transport Stream Monitor User Manual Interface Configuration and Interpretation Receiver Mode In order to achieve high accuracy measurements particularly for MER and SNR measurements the COFDM IF card supports two modes of operation For conventional COFDM reception a relatively low ultimate SNR is acceptable For example at 64QAM an ultimate receiver SNR of 30 dB can result in a reduction in system performance of only 0 5 dB However for more detailed analysis of COFDM constellations a much higher ultimate SNR is required preferably in excess of 40 dB For this reason two modes of COFDM operation are provided High Sensitivity mode gives the full dynamic range of a conventional COFDM receiver but at the expense of ultimate SNR The High Resolution mode modifies the signal path to dramatically reduce the noise generated in the receiver giving a much higher ultimate SNR but at the expense of receiver sensitivity So for general purpose monitoring where the input signal may vary over a wide range typically 75 dBm and lower high sensitivity mode is preferred If the signal is consistently greater than 50 dB high resolution mode provides better RF measurement performance IF Filter The COFDM receiver incorporates two stages of selectivity One of these can be bypassed in WIDE mode to give a more accurate representation of the input spectrum flatness at the expense of overall selectivity Stream Priority When hierarch
