Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 15151.1-1994 "frequency counter general technical conditions" and GB/T 15151.2-1994 "frequency counting
Test Methods. "
This standard and GB/T 15151.1-1994 "frequency counter general technical conditions" and GB/T 15151.2-1994 "frequency counter
Test methods "compared to the main changes are as follows.
--- Original two standards into one standard;
--- Delete the reference standard and this standard is no longer used in the existing terms and definitions;
--- Remove the "adaptive waveform" "Measurement indicates" "Self-Test" "Coupling" "low pass filter" "BCD code output," "special requirements" "Other
Requirements "requirements and test methods; (see GB/T 15151.1-1994 in 4.5,4.9,4.11,4.18,4.20,4.26);
--- Added "frequency modulation (FM) tolerance," "automatic amplitude recognition" "Day timebase frequency fluctuation" "frequency stability" base date "stable timebase
Time "requirements and test methods (see 4.12,5.12);
--- Updated the "Security" "environmental compatibility", "Transport Packaging", "Electromagnetic Compatibility" "Power," "reliability" "Dimensions and weight" requirement
And test methods (see Chapter 4, Chapter 5);
--- Update "Quality inspection rules" in the part (see Chapter 6).
The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This standard by the National Standardization Technical Committee Electronic Measuring Instruments (SAC/TC153) centralized.
This standard was drafted. China Electronics Technology Group Corporation Research Institute 11.
The main drafters of this standard. Liu Jun, Xu Jianhua, Zhang Wei, Du Nianwen, Choeng Mon Ying, Wang Wei Liang.
This standard replaces the standards previously issued as follows.
--- GB/T 15151.1-1994, GB/T 15151.2-1994.
