Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard is GB/T 8496-1987 "television broadcast receiver electronic tuner basic parameters and measurement methods" amendments. This standard and GB/T 8496-1987 compared to the main changes are as follows. a) Based on the current status of technology and products for the power gain, noise figure, two indicators have been adjusted. b) According to the current testing equipment and methods used by the manufacturers of the actual test conducted on the high-frequency amplitude-frequency characteristic of reflection loss measurement method Modified. c) the original standard input of the local oscillator interference voltage, the local oscillator radiation interference field strength has been unable to meet the new national standard related to electromagnetic interference and Immunity characteristics requirements. This revision these two indicators combined into one --- EMC performance requirements, and cited new Related GB , respectively. GB 13837 and GB/T 9383. d) DIMENSIONS claim to "press manufacturers and technical specifications," while deleting Appendix B. e) Since the original standard-setting time earlier, the format does not meet the GB/T 1.1-2009 requirements, revision of standard format Modified. This standard replaces GB/T 8496-1987 "television broadcast receiver electronic tuner Basic parameters and methods of measurement." The standard proposed by the People's Republic of China Ministry of Information Industry. This standard by the national audio, video and multimedia systems and equipment Standardization Technical Committee (SAC/TC242) centralized. This standard was drafted.
