With the development of science and technology, some application systems, such as large communication systems, power systems, especially high speed moving target tracking and positioning systems, have put forward higher and higher demands on the accuracy of time interval measurement. At the same time, the application of time interval counters in China is more controllable, and more inclined to rely on domestic equipment to realize the research and development of digital frequency meters.

Although the measurement error of the universal counter can not be fundamentally eliminated, but through in-depth analysis of the causes of the conversion error, quantization error and various errors, we can work out a relatively effective way to reduce the error. With the continuous improvement of the electronic counter and the continuous improvement of the method of error reduction, we believe that the measurement cycle error will be reduced to the minimum.

The general counter is easy to operate, because the computation range of general counters is generally from 1 to 90 thousand. General counters usually have four buttons. We can design and convert these four functional buttons. When you use a general counter, you need to set it up because the general counter is different from the ordinary counter. Smart counters usually have memory functions, so after we use them, we'd better clear the data and reset them.

The domestic frequency meter recommended model is the SYN5636 type high precision general counter. It is a time-frequency testing instrument developed in accordance with the verification regulation of JJG 349-2014 universal counter.The universal counter can be used as a time base for a constant temperature crystal oscillator or a rubidium clock. The standard product is a temperature compensated crystal oscillator base. At the same time, it has two functions of measurement and statistics. Measure frequency, cycle, frequency ratio, input voltage maximum / minimum / peak value, time interval, pulse width, rise time / fall time, duty cycle, phase and so on. Statistics (mean, standard deviation, maximum, minimum, peak value, count, Allen variance).

SYN5636 counters generally use the industry and scenario for time and frequency measurement in the fields of aerospace, missile, weapons and other fields such as time measurement and crystal oscillator, electronic components and other scientific research and metrology.

The general counter is characterized by its high accuracy, wide measuring range, many functions, simple operation, fast measuring speed, direct display of numbers, and easy realization of automatic measurement process. A technology product that can be applied in many areas of the modern society, especially in industrial production and scientific experiments, is widely used.

The equipment can be used as advanced domestic frequency meter. It can also measure cycle and phase difference in addition to meeting simple frequency requirements. Because of its complete functions, various aspects of performance indicators are relatively good, with high accuracy and sensitivity, wide measuring range and other characteristics, it has won a good reputation.
