This paper gives a simple functional description of the frequency meter, and makes a brief summary of the brand characteristics of several different frequency meters applied in the market, so as to facilitate users to refer to the choice of the frequency meter brand and the applicability of the frequency meter function.

The frequency meter, as the name suggests, is the abbreviation of the frequency counter. It is an electronic test equipment specially designed to test the frequency of the measured signal. The concept of frequency is the reciprocal of the signal cycle. It is the same as the number of cycles per unit time. At present, all frequency counters exist in the market, including low-grade, all the frequency meter devices at home and abroad are basically the same in design principles. The design is mainly composed of the time base circuit, input circuit, counting display circuit and control circuit which we can query, and constitute all components of the frequency meter function realization.

The frequency meter brands used in the domestic market are mainly made up of two parts: Chinese manufacturers and European and American manufacturers. The frequency meter brand has entered a large part of the market in China. The manufacturers in China have done a lot of research and development in the past few years, and have promoted several brands of frequency meters. The frequency meter made by manufacturers specializing in time and frequency is more professional and clearer in terms of the main functions and needs of the cymometer.

Europe and the United States market is mainly the Swedish Pendulum Instruments company, its frequency meter R & D results technology was first derived from the Philips company's time and frequency departments, in the field of time and frequency measurement has rich experience in R & D and production, currently the main domestic application of the frequency meter type has CNT-91, CNT-90, CNT-81, CNT-85. Another European and American manufacturer mainly used in the domestic market is the Agilent technology company in the United States, mainly in the field of electronic measurement. Currently, the frequency meter models used in the domestic market are 53181A, 53131A and 53132A.

At present, the frequency meter brand of our country is mainly composed of uni and victories. Xi'an has a frequency meter that can be supplied to the market at the same time. The frequency meter made by und is a simple frequency counter used in electronic counting in vibration. The victory brand is mainly an electronic measuring instrument, and the current frequency meter is VC2000. Since its inception, Xi'an has been focusing on the research of time and frequency systems, involving the development of time and frequency synchronization and time frequency testing. The frequency meter currently sold abroad is SYN5637 type high precision frequency counter.

With the development of electronic measuring instruments in China, the progress of localization of electronic measuring instruments will be imminent. As a manufacturer of time and frequency fields, Xi'an will continue to focus on the research and development of time and frequency measuring instruments. The SYN5637 type high precision frequency counter that we mentioned today is currently applied to meet all domestic regulatory requirements. It can be compared with European and American brands, and can be customized according to the requirements of users.
